1 Introduction

Eco Link & Uniconfort were seeking independent testing of their Uniconfort EOS 90 boiler

installed at Kernock Park Plants the result from which will be used to determine if the boiler

can be considered for smoke emissions exemption and can also be included on the Energy

Technologies List.

The test work was carried out on site at Kernock Park Plants, Saltash, Cornwall. The unit

was test fired at high fire during the morning of 11th April 2013 with wood chip, and at low

fire during the afternoon of the same day. The flue gas composition was measured to

enable an output and efficiency to be calculated by the indirect (or losses) method

described in BS EN 845: part 1.

3 Test work

3.1 Test Appliance

The unit supplies LTHW to the various glass houses and buildings that comprise Kernock

Park Plants.

Figure 1 EOS Uniconfort boiler

For the test programme, the boiler was operated by staff from Eco Link and Uniconfort,

whilst being managed by the site manager.

3.2 Test Equipment

The flue gas was sampled close to the exit of the flue for continuous measurements of CO2,

CO, O2, and NOx by the methods described in ISO 12039:2001, BS EN 15058:2006, BS EN

14789:2005, and BS EN 14792:2005 using a probe, sample line and gas conditioning

system. CO2 and CO were analysed using a multi-range infra-red analyser, O2 using a

galvanic cell, and NOx using a chemiluminescence analyser. In addition, total particulate

matter was sampled to the procedure described in BS EN13284-1 using an Andersen

Universal stack sampler with quartz micro-fibre filter element of collection efficiency of

99.91% > 0.1 micron.

The actual equipment used is detailed in the attached report from Shield on Site Services

who carried out the emissions tests.

3.3 Test Fuel

The test fuel was wood chip. Samples have been fully analysed by Knight Energy Services

(an EN17025 accredited analytical laboratory) and the results appear at section 7.

3.3.1 Fuel feed rate

It was not possible to break into the fuel feed system, therefore a method of measuring the

fuel feed rate was devised.

Wood chip was delivered to the biomass using a dual screw system. Chip from the storage

shed was delivered via a moving floor to the first screw. From there the chip was then

delivered to the boiler feed screw where it was supplied to the combustion chamber.

The feed screw was timed to operate at set on/off cycles allowing a controlled mass of fuel

to be delivered to the boiler and thus steady heat output achieved. The cycle timings were

calculated depending of the heat output of the boiler and were varied for high and low fire

test periods.

Each on/off cycle during the test periods was timed and the total number of cycles

calculated. This was then compared to the actual set paramaters as set by engineers from

Uniconfort on site to ensure the calculated feed rate was comparible to the boiler settings. It

was estimated that the screw was filled to 50% capacity to account for the volume of the

screw within the feed chamber and feed rates were estimated as an average of 280kg/h at

high fire and 94kg/h at low fire.

3.4 Test Procedures

The boiler was tested for a total of 3 hours. The gas analyser logged at 15 second intervals

throughout the test. Raw gas data is available on request.

The boiler output and efficiency was calculated according to the method given in BS 845:

part 1 1987 (the indirect or losses method) by Kiwa staff. Kiwa is accredited by UKAS to

carry out boiler efficiency testwork and calculations to this standard.

Continuous measurements of CO2, CO, O2, and NOx were made by Shield on Site Services

using the methods described above in Section 3.2. A probe, sample line and gas

conditioning system were used. Shield on Site Services is accredited by UKAS to carry out

stack emissions measurements to these standards.

4 Results and discussion

4.1 Results

The boiler was tested for a total of 3.5 hours, with each individual test lasting 30 minutes.

The first test was carried out to allow the emissions monitoring team to calibrate their

equipment and thus the results for that test period have been emitted from this report.

Three high fire (100% load) and three low fire (~30% load) tests were carried out and the

results are shown below. The first table shows the measured efficiency of the boiler at high

and low fire; the second table displays the emissions of the test period.

4.2 Discussion

Overall the tests showed very stable conditions throughout with good repeatability

achieved. The results collected indicate the boiler was operating consistently during both

high and low fire conditions and provide results within the expected range of operation.

The full chemical analysis of the wood chip is given in Section 7 and a summary of the

results for each test run, together with the calculated efficiencies and output of the

appliance, are provided in Section 8. The emissions report from Shield Onsite Services

accompanies this report (Section 9).

The tested boiler was rated at 990kW and the calculated output is indicative of this rating.

When comparing the calculated output using BS845 with the measured output using an

estimated fuel delivery, the closure is good averaging 97%, providing additional confidence

in the collected results.

The fuel used for the test period was reasonable, with a measured moisture content of

22.3% during the fuel analysis. The calorific value of the fuel was 14.077MJ/kg (Net) and

15.663MJ/kg (Gross).

Average particulate emission over the three high fire sampling periods was 78.1g/h and

21.5g/h over the low fire sampling periods. When expressed on the basis of gram of

pollutant per net gigajoule of fuel input energy, these equate to 20g/GJ and 16g/GJ, for high

and low fire respectively.

Average Oxides of Nitrogen emission over the three high fire sampling periods was 303g/h,

and 90g/h over the low fire sampling periods. When expressed on the basis of gram of

pollutant per net gigajoule of fuel input energy, these equate to 76g/GJ and 68g/GJ, for high

and low fire respectively.

During the high fire test, the net boiler efficiency was 92.1% and the gross boiler efficiency

83.4%, see section 8. The greatest losses being due to losses in the flue gas, especially

losses associated with the enthalpy of the water vapour and the sensible heat.

During the low fire test, the net boiler efficiency was 90.5% and the gross boiler efficiency

81.9%, see section 8. The greatest losses being due to losses in the flue gas, especially

losses associated with the enthalpy of the water vapour and the sensible heat.

5 Conclusions

The results of the testwork show the following:

Net efficiency was calculated to be 92.1% (83.4% gross) during the high fire test

and 90.5% net, (81.9% gross) at low fire.

The average particulate emission was 20 g/GJ during high fire and 16 g/GJ during

low fire.

The average NOx emissions were 76 g/GJ in the high fire test and 68 g/GJ in the

low fire test.

The calculated average energy outputs were 1015 kW (high fire) and 333 kW (low

fire).

Firing

There are no CEM's equipment currently installed.

A waste gas homogeneity test to BS EN 15259:2007 (MID) is not required:-

The homogeneity test is not applicable to duct areas less than 1m2.

All monitoring was performed in accordance with the relevant procedures.

The sampling location is a vertical stack.

The calculated particulate emission level was greater than the control blank.

The velocity and temperature profile at the sampling location met the requirements of BS EN 13284-1: 2002 when on High Fire, however this

was not the case when on Low Fire as the minimum Pitot reading was less than the 5 pascals required.

When the results that are expressed as non-detected the mass emission has been calculated from the detection limit and therefore they

are worst case results.

The particulate monitoring was within the required 95 to 115 % isokinetic rate as stated in BS EN 13284-1: 2002

Sampling could only be undertaken from one sampling port as a result of insufficient platform size and restricted access.

cell analyser. The analytical equipment detailed above is calibrated before and during the tests using certified gas

mixtures of nitrogen and oxygen. Sampling points are selected in accordance with the findings of any BS EN 15259

assessment.

Documented in-house procedure TPM/05 to the main procedural requirements of BS EN ISO 9096:2003. Stack

gases are extracted from representative sampling points at isokinetic flow rates through a sharp-edged nozzle.

Particulate matter is collected on a pre-weighed filter conditioned at 180oC. Deposits upstream of the filter are also

recovered and weighed. The increase of mass of the filter and mass collected upstream of the filter is divided by the

volume sampled to determine the mass concentration.

Emission Monitoring Procedures And Instrumentation

Documented in-house procedure TPM/01 to the main procedural requirements of BS ISO 9096:2003 and BS EN

13284:2002. Velocity and temperature measurements are performed using a calibrated Pitot tube, as described in

BS ISO 10780:1994 and a calibrated thermocouple. Velocity and possible flow deviation measurements are carried

out at selected, representative points in the gas stream.

Documented in-house procedure TPM/37 to the main procedural requirements of BS EN 14790:2005. A measured

volume of gas is extracted from the gas stream through a moisture trapping unit. The mass gain of moisture trapped

is divided by the volume of gas sampled to determine the mass concentration of water vapour. For water saturated

stacks the temperature of the gas stream is measured and the water vapour concentration is determined using

liquid-gas equilibrium tables. Sampling points are selected in accordance with the findings of any BS EN 15259

assessment.
