REPORT SUMMARY

In order to meet the requirements of the South African Air Quality Act No. 39 of 2004

(Reference 9.1), all Solid Fuel Combustion Installations (Category 1.1) such as Matimba Power

Station, are obligated to monitor several listed pollutants during operation. These pollutants

include particulate matter, Sulphur Dioxide and Oxides of Nitrogen. The Act further implies

that all emission programs are required to meet international standards such as EN 14181

(Reference 9.2) and EN 15259 (Reference 9.3). To this end, and in keeping with the ESKOM

Standard for Emission Monitoring and reporting 240-56242363 (Reference 9.4), ESKOM

scheduled a series of emission measurements on Units No. 1 to 6 at Matimba Power Station.

The emission measurements were scheduled to be conducted in parallel with the permanently

installed Automated Measuring System or AMS on these Units. The data collated during the

parallel measurements on the particulate emissions AMS was to be used in determining an

AMS calibration function, calibration range and operational variability as required by ISO

10155. The data collated during the parallel measurements on the gaseous emissions AMS was

to be used to determining the continued validity of their current QAL2 calibration functions, as

specified in EN 14181.

Most Automated Measuring Systems or AMS require calibration to known quantity in order to

ensure accurate measurements. It is however not sufficient to use simulated reference material

alone to determine a calibration function for a gaseous emission AMS as the reference material

cannot replicate the complex and dynamic gas matrix present in an open operational system. It

is therefore necessary to determine a calibration function for each individual plant from the

actual conditions present using a parallel Standard Reference Method or SRM such as is

described in EN 14181 and ISO 10155. Such procedures must be conducted over a range of

operating conditions representative of a plant’s general conditions and typically consist of a

series of 5 to 15 individual measurements.

Stacklabs, an environmental testing laboratory, was contracted to complete the required Annual

Surveillance Tests and to determine the calibration functions as described in the EN 14181 and

ISO 10155. All the required site measurements were carried out during the period from 20th of

September to the 28th of October 2016. All the relevant results and calibration functions have

been presented in this report and may be summarised as presented in the following pages:

at a level of approximately 160m above ground level (Level 6). Averages of the particulate

emission, pressure, temperature and moisture measurements were determined from conducting

traverses through 20 sectors, distributed along two diameters set at 90° to one another within

the stack gas flow profiles. All gaseous sampling was conducted statically, at the best available

sampling points, previously determined for each flue as follows:

Unit No. 1 Right of Centre Port (A) depth at Point 4 or 1.595m from Stack inner wall

3. Methods & Procedures

3.1. Particulate Emissions

The method selected for the determination of the particulate emission concentration on Unit

No. 1 to 6 was in compliance with ISO 12141 Stationary source emissions - Determination of

concentration of particulate matter (dust) at low concentrations – Manual gravimetric method.

This general method can be briefly described as follows:

A sharp-edged nozzle is positioned in the duct facing into the moving gas stream and a sample

flow of the gas is extracted isokinetically for a measured period of time. To allow for non-

uniformity of the distribution of particulate concentration in the duct, samples are taken at a

pre-selected number of stated positions in the duct cross-section. The particulate matter

entrapped in the gas sample is separated by a filter medium, then dried and weighed. The

particulate concentration is calculated from the weighed particulate mass and the gas sample

volume. The particulate mass flow rate is calculated from the particulate concentration and

the duct gas volumetric flow rate. The particulate mass flow rate can also be calculated from

the weighed particulate matter, the sample time, the area of the sample plane and the nozzle

opening.

The degree to which this sample represents the total gas flow depends on

Homogeneity of the gas velocity within the sampling plane;

A sufficient number of sampling points in the sampling plane;

Isokinetic withdrawal of the plane

As stated above, the gas has to be sampled at more than one sampling point in the sampling

plane, dependant on the sampling plane area. This plane is normally divided into equal areas,

at the centres of which gas is withdrawn. To determine the particle concentration in the plane,

the nozzle is moved from one sampling point to the other, extracting gas isokinetically at each

point. Sampling periods should be equal for each sampling point, resulting in a composite

sample. If equal sampling areas cannot be chosen, the sampling period shall be proportional

to the sampling area. The sample is extracted through a sampling train, which principally

consists of:

A sampling probe tube with entry nozzle;

A particle separator;

A gas metering system, in-stack or external;

A suction system

The particle separator and / or the gas metering system may be located either in the duct, or

placed outside the duct.

It is necessary to avoid condensation of vapour in the sampling train during gas sampling,

because it will interfere with particle separation, particulate condition and flow measurements.

To this end, the probe tube, the particle separator and the gas flow-measuring device may be

heated above the relevant dew point where necessary. The water vapour may intentionally be

removed downstream of the particle separator, to make use of a dry gas meter for the

measurement of sampled gas volume.

For isokinetic sampling, the gas velocity at the sampling point in the duct has to be measured,

and the corresponding sample gas flow has to be calculated and adjusted.

Page 22: Matimba Power Station Units No. 1 to 6 Automated Emission ......10155. The data collated during the parallel measurements on the gaseous emissions AMS was to be used to determining

# Matimba Power Station Units No 1 to 6 Correlation Aug & Sep 2014 Report No. RSL229 Page 4 of 294

Normally a Pitot static tube is used for the measurement of duct gas velocity. If the sample gas

flow-measuring device is used within the duct, the relationship between the measured pressure

drop and the pitot static tube differential pressure is simple, facilitating the adjustment to

isokinetic conditions. If the gas meter device is situated outside the duct, the calculation of the

isokinetic sample gas flow rate is more complicated. The calculation may also include the duct

gas density under standard conditions (which may be derived from the dry gas composition and

the moisture content), the temperature, static pressure of the gas in the duct, the gas meter

device, and the water vapour content of the duct gas, if the sample gas flow is measured after

water removal.

After sampling, the collected particulate matter is completely recovered, dried and weighed and

the concentrations are determined.

All Stacklabs isokinetic sampling is carried out employing procedures and equipment that

comply with the requirements of ISO 9096 12141 1992 (Reference 1). All Stacklabs sampling

equipment is calibrated by SANAS accredited laboratories.

Matimba personnel were responsible for the setting of the plant prior to the test period.

The broad outlines of filter weighing, pre-test preparations, sampling system integrity checks

and sampling procedures are discussed in Appendix No 3.

3.2. Oxides of Nitrogen (NOx reported as NO2) & Sulphur Dioxide

The methods selected for the determination of the Sulphur Dioxide and Oxides of Nitrogen

were EN 14792 and EPA Methods 6C respectively; EN 14792 Determination of mass

concentration of nitrogen oxides (NOx) Reference Method Chemiluminescence, also portions

From EPA 7E—Determination of Nitrogen Oxides Emissions from Stationary Sources

(Instrumental Analyser Procedure); EPA 6C—Determination of Sulphur Dioxide Emissions

from Stationary Sources (Instrumental Analyser Procedure).

These two procedures are essentially the same, with the exception of the two differing analytes

and the detection principles.

A heated stainless-steel nozzle and sampling Probe (M&C PSP 4000-H) was positioned in the

duct with the nozzle facing into the moving gas stream and a sample flow of the gas was

extracted non-isokinetically. The gas was passed through a heated ceramic filter which

separated and entrapped any particulate matter suspended in the gas. The sample gas was

then passed through a heated Teflon tube to a gas conditioning unit (M&C PSS-5) which

removed the moisture in the sample gas and reduced the gas temperature to approximately

4°C. The sample gas then continued through a Teflon tube into a manifold equipped with a

flow controller to a sample analyser where the SO2 and NOx volume concentrations were

determined utilising NDIR (pneumatic) & Chemilluminescence (cross flow modulation)

principles. The sample analyser used was a Horiba PG250 with the following specifications:

# Matimba Power Station Units No 1 to 6 Correlation Aug & Sep 2014 Report No. RSL229 Page 5 of 294

The response time on site with the M&C PSP 400-H probe and M&C PSS-5 gas cooler was

measured as 1 minute and 32 seconds for 98% concentration.

3.3. Oxygen (O2), Carbon Monoxide (CO) & Carbon Dioxide (CO2)

The methods selected for the determination of Carbon Dioxide (CO2) & Oxygen (O2) were EN

EPA CTM-030, Instrumental method with NDIR and EPA CTM – 030 with a Zirconia cell

respectively. The sampling system and procedure for the Carbon Dioxide & Oxygen was

essentially the same as that which has been described above for the Sulphur Dioxide and

Oxides of Nitrogen pollutants.

3.4. Stack Gas Temperature, Pressure and Moisture concentrations

The methods used for determining the SRM peripheral parameters, gas Temperatures, Pressures

and Moisture Content were in compliance with EPA Methods 2 & 4 and ISO 12141 –

(Determination of concentration of particulate matter (dust) at low concentrations – Manual

gravimetric method).

This general method for the moisture concentration can be briefly described as follows:

A sharp-edged nozzle is positioned in the duct facing into the moving gas stream and a sample

flow of the gas is extracted for a measured period of time. The moisture in the gas stream is

cooled and condensed in a gas cooler equipped with a silica gel trap. The volume of gas

sampled is totalised by a gas volume meter. The increase in moisture condensate, collected in

the gas cooler, is determined gravimetrically and the moisture concentration is calculated as

follows:

Vwsg(std) = (Wf – Wi) /ρ

Where:

Wf = Final weight of silica gel & impinger (g)

Wi = Initial weight of silica gel & impinger (g)

ρ = Density of water vapour at NTP (0.804 kg/m3)

Vwsg(std) = Volume of water vapour collected in silica gel (g) at NTP

Vwsg(std)

Bws = -------------------------

Vwsg(std) + Vm(std)

Where:

Bws = Proportion of water by volume %v/v

Vm(std) = Dry gas volume measured by dry gas meter (Nm3 dry)

3.5. Plant Operation

ESKOM personnel were responsible for operating the plant prior to and during the

measurement period. The broad outlines of operating procedure have been discussed in Section

No. 2 above and the detailed plant parameters have been presented in Appendix No 3.

5. Discussion

5.1. Unit No. 1 Total Particulate Matter (TPM) Monitor Correlation

The correlation on Unit No 1 was completed from the 17th to the 26

th of October 2016. A total

of 12 measurements were conducted. The following trends indicate the AMS monitor output

signals captured during the correlation period.

The measured particulate emission concentrations ranged from 5.3 to 25.2 mg/Nm3 Dry @ 10%

O2, well below the negotiated cap value of 100 mg/Nm3 Dry @ 10% O2. The corresponding

particulate emission monitor signals, recorded from Output No. 1 (0 to 1.7 OD), ranged from

4.3 to 5.1 mA over an operating range of 425 to 676.1 MW. The resulting co-ordinates

6. Monitoring Deviations

6.1. There were no significant deviations from either the ISO 10155, 12141 or the ESKOM

Standard for Emission Monitoring and Reporting (420-56242363), with regards to the

measurements during the correlation of Unit No 1 to 6.

7. Recommendations

It is recommended that:

7.1. The particulate emissions from Units No. 1 to 6 reported to the authorities are determined with

the correlation function presented in Figures No. 1 to 12 of this report.

7.2. The gaseous emissions from Units No. 1 to 6 reported to the authorities are determined with the

function presented in Reports No.:

LEV1409M-Report-R2591-hbSIA ESKOM Matimba Unit1 – V5

LEV1409M-Report-R2592-hbSIA ESKOM Matimba Unit2 – V3

LEV1409M-Report-R2593-hbSIA ESKOM Matimba Unit3 – V3

LEV1409M-Report-R2595-hbSIA ESKOM Matimba Unit5 – V4

LEV1409M-Report-R2596-hbSIA ESKOM Matimba Unit6 – V4

This is recommended, as the Annual Surveillance Test results for Unit No. 1 to 6 support the

continued validity of the calibration functions derived in 2014.

7.3. Annual Surveillance Tests again be conducted on all the Automated Monitoring Systems at

Matimba Power Station during the third quarter of 2017.

7.4. New compliant particulate emission monitor correlations are conducted on Unit No. 1 to 6 during

the third quarter of 2018.

1. FILTER WEIGHING

Before the test, the filters are prepared as follows:

The required numbers of filters are marked with a unique number. The filters are then heated

in an oven at 120 degrees Celsius for a period of one hour. After heating, all the filters are set

out together with three reference filters in a dedicator where they will condition for a period of

48 hours. Each filter is then weighed three times, in a temperature controlled clean room,

where the masses are captured on a dedicated computer system. Following the weighing

process, the filters are packed and sealed into a separate container ready for use. The reference

filters are treated in the same manner as those earmarked for the tests, but are not taken to site.

After the site measurements, the used and reference filters are again set out in the desiccators

and allowed to condition for up to 100 hours. The same weighing procedure is again followed

and the final contaminant masses are calculated by the computer system.

2. PRE-TEST PREPARATIONS

On site, the equipment is set up at the measuring location. The inside dimensions of the duct

are determined. The number of test points per traverse is determined according to the standards

and the sampling probe marked accordingly

3. SAMPLING SYSTEM INTEGRITY

A leak check is performed on the impulse lines to ensure measurement integrity.

With each change in filter or any other operation which might influence the integrity of the

vacuum system, a vacuum check is performed. This ensures that only the gas which entered the

nozzle will be measured by the gas test meter. Gaseous analysers are zero and span checked

with calibration gas at the measurement points.

4. SAMPLING PROCEDURE

Gas temperature, pressure and velocity head readings are logged at each sampling point.

Velocity head readings are updated at intervals of 1 minute. During this time, the computer

program calculates the orifice flow settings required for isokineticity and the flow is adjusted

accordingly with each update, either automatically or manually depending on the particular

system used.

Oxygen in the flue gas is measured to determine gas density.

An orifice flow meter is used to facilitate the adjustment of the sampling flow rate at one-

minute intervals. The relevant parameters for flow calculation are entered into the computer.

The computer is programmed to determine the flow rate through the orifice in order to achieve

isokineticity. A dry gas meter is incorporated into the sampling train and is used to record the

total actual volume sampled and therewith to determine the percentage isokineticity.

Moisture is separated from the sampled gases during sampling, using a water trap and silica gel.

The ‘A’ indicator in the silica gel changes colour as moisture is absorbed. The accumulated

liquid is used after the test to determine the moisture content on a percentage-by-volume basis.

This value is again incorporated into the volume of dry gas sampled to determine the

concentration of pollutants in the gases at Actual and Normal (sometimes referred to as

Standard) conditions.

The uncertainty before the test, about the moisture content in the gas, fluctuation in the gas

flows and human error contribute towards the final deviation from 100 % isokineticity.

# Matimba Power Station Units No 1 to 6 Correlation Aug & Sep 2014 Report No. RSL229 Page 228 of 294

After completion of a measurement the relevant sampling components may be rinsed in order to

capture pollutants that may have become attached to the sampling system’s exposed surfaces.

The rinse medium is captured and contaminants within will be added to the total sampled mass.

Relevant plant operating parameters are logged, where possible, for reference purposes and it is

usually recommended to take raw product samples during the tests. The content of certain

elements in the raw product has specific bearing on plant performance and is useful for

comparative reference.

On completion of all the site measurements the equipment will be removed from the plant,

returned to the laboratory and work shop for processing and cleaning. Where necessary,

additional calibration checks will be conducted on specific instruments to determine operational

continuity.
