Product Overview Emission MonitoringAmbient MonitoringEnvironmental and Process Data Management Systems

Introduction Monitor selection

The DURAG GROUP develops and manufacturesproducts in the field of environmental measur-ing technology for measuring and monitoring

● dust concentration and opacity

● total mercury concentration

● flue gas volume flow

as well as evaluation systems for the calculationof emissions.

The products are used worldwide in power gen-eration plants and the process industry, such ase.g. fossil fuel power stations, waste incinerationplants, refineries, chemical processing plants,cement works, the lime industry, the steel indus-try, filter and dust extraction plants as well as formonitoring ambient air.

The DURAG Group is known for its high stan-dards of quality. DURAG has been ISO 9001 cer-tified for a number of years and has fully imple-mented the corresponding requirements. Theproducts are manufactured to national, Euro-pean and international standards.The following are taken into account:

● VDI 2066 / VDI 3950 – German dust meas-urement standard

● EN 14181 – European quality assurance stan-dard for automatic measuring equipment

● EN 13284 – European standard for determin-ing small dust concentrations

● EN 14884 – European standard for determin-ing total mercury concentration

● EN 12341 – European standard for determin-ing PM10 airborne dust

● ISO 10473 – International standard for betaabsorption method

● ASTM D-6216.98 – American dust measure-ment standard.

DIN EN 14181

DIN EN 14181 defines three so-called quality as-surance levels (QAL) and an annual functionaltest (AST) for automatic measuring systems:

● QAL 1: Requirement for use of automaticmeasuring equipment that has had its suit-ability tested (the test complies with DIN ENISO 14956)

● QAL 2: Installation of automatic measuringsystem (AMS), calibration of AMS using thestandard reference method (SRM), determina-tion of measuring uncertainty / variability ofAMS and check for observance of presetmeasuring uncertainties

● QAL 3: Continuous quality assurance by theoperator (drift and precision of the AMS, veri-fication on control card)

● AST: Annual surveillance test including SRMmeasurements to check the uncertainty ofthe AMS values.

DIN EN 14181 prescribes which characteristicsautomatic measuring equipment must possess,and how they must be calibrated and main-tained. In addition to the calibration function,measurement inaccuracy - which plays a deci-sive role in the validation of the measured val-ues obtained during continuous monitoring - isalso determined from the data of the calibra-tion. In addition, the requirements for the un-certainty of the measured values obtained withthe measuring equipment, which are defined inthe EU directives relating to large combustionplants, waste incineration plants and waste co-incineration plants, are checked using a methoddescribed in the standard.

QAL 1 – Testing the suitability of theequipment technology

QAL 1 specifies the suitability of a measuringdevice by calculating the total measuring uncer-tainty according to EN ISO 14956 before installa-tion, by taking account of all potential influ-ences.

Devices that have passed the TÜV suitability testand have been established as suitable measur-ing devices generally fulfil the standards ofQAL 1.

QAL 2 – Installation and calibrationcheck Selection of the measuring location and correctinstallation of the measuring device. Calibrationof the device using a standard reference me-thod, min.15 measuring points distributed over3 days, determination of the calibration curve orcurves in different operating conditions (fuels,load, etc.) and definition of the area of validity ofthe calibration curve.

Calculation of the total measuring uncertaintyof the measuring device.

QAL 3 – Continuous monitoring

Regular checks of the zero and reference pointdrifts during the plant operation by the operat-ing personnel should ensure reliable and cor-rect operation of the measuring device.

AST – Annual inspection

The calibration curve found in QAL 2 must bechecked / confirmed annually by means of 5parallel measurements.

In addition to the general data, such as de-sired measurand or measuring range, specialaccount must be taken of the plant conditionsat the measuring location when selecting asuitable measuring device, especially in thecase of dust concentration measurement.

OpacityA light beam sent through a mixture of gas andparticles is attenuated by absorption and diffu-sion. The more particles are found in the lightbeam, the stronger the opacity. The ratio of re-ceived light to initial light is a measurement ofthe transmission or the reciprocal opacity.

Extinction By converting the transmission to extinctionand after a gravimetric comparison measure-ment the display is in mg/m3. For dust concen-trations this result is displayed in mg/Nm3 bycalculation with the reference units T, P, RF.

Scattered light A light source emits light which is diffused byparticles in the gas and recorded by a detector.The scattered light principle is suitable for smalldust loads to under 1 mg/m3. The relationshipbetween measured value display and dust loadis determined by means of gravimetric compa-rison measurement.

Smoke spot number (soot) Scattered light measurement with very lowmeasuring range.Smoke spot number 1 corres-ponds to approx. 100 µg/m3. A comparisonmeasurement determines the relationship bet-ween display and smoke spot number.

TriboelectricityTriboelectricity results from friction betweenbodies or particles. If these charged particlesstrike a measuring probe, an electron transfertakes place. The value of the charge is a measu-rement for the dust mass flow rate. The relati-onship between measured value display anddust concentration can be determined by agravimetric comparison measurement.

Dew point Every gas mixture contains a defined quantityof humidity. The maximum possible saturationhumidity is dependent on the temperature: ifair is continuously cooled, with constant abso-lute air humidity the relative air humidity in-creases up to 100%. If the air is further cooled,the humidity condenses as water drops and af-fects the measuring result in optical and triboe-lectric measuring procedures.

TemperatureThe ambient temperature of the measuringhead may be maximum 50°C. In optical sys-tems, the purge air is also used as cooling airand separates the hot exhaust gas through thepurge air buffer. In transmission systems, thestandard assembly connection can be used upto an exhaust gas temperature of 200°C. Beyond this, the connection must be extended(approx. 1 mm / 1°C).

Pressure The standard purge air blower can be used upto a channel overpressure of 20 hPa. Beyondthis, special blowers are available. A flap valveshould be used in the event of overpressures. 2

Measuring principle

● The tribo probe measures the electric chargeof the incident particles.

● The measurement of the volume flow isbased on the mechanical action principle. Theprobe has two separate chambers, betweenwhich a differential pressure builds up underflow.

● The absolute pressure in the flue gas ismeasured by a pressure transmitter in onechamber of the probe.

● The temperature is measured directly in thecentre of the flue gas flow in a separate cham-ber within the probe with a temperature sen-sor.

● Dust concentration is calculated from the triboelectric measuring signal and the vol-ume flow. To this purpose in calibration, youreceive the necessary parameters for the rele-vant speed ranges, which form the basis forcalculating dust concentration. The raw datathat are also measured for gas temperatureand absolute pressure are used to calculatethe standard dust concentration and the stan-dard volume flow (wet).

Measuring principle

The filter monitor uses the triboelectric effect todetermine dust loads in flowing gases. The elec-trical charge which the dust particles experi-ence due to friction is picked up by a probe pro-truding into the dust channel and converted in-to a measuring signal by electronics. Themeasuring signal is proportional to the dustconcentration and is calibratable at a constantgas speed.

Measuring principle

The measuring principle of the F-701-20 am-bient dust monitor is based on the absorptionof the beta rays (electrons) emitted by a radio-active emitter through particles collected froman ambient air flow. In the F-701-20 the pulse rate of the unloaded filter tape is measured be-fore each collecting cycle, then dust is collectedon this precise filter spot over a pre-defined period, and finally the pulse rate of the loadedfilter tape is measured. The difference betweenthe two pulse rates is evaluated in the deviceand displayed as dust concentration in µg/m3.
