Part of the NO2 is in a photochemically excited state. Whenreturning to the basic state, these NO2 molecules can radiate light in the wavelength range of 590 nm to 3.000 nm. The intensity of this light depends on the NO content and is influenced by the pressureand presence of other gases. Figure C.2 shows an example for the basic arrangement of a chemoluminscence analyser. There are atmospheric pressure and low pressure analysers, depending onthe pressure in the reaction chamber. Some analysers have built-in NO2/NO converters and, because of their structure, give signals for NO, NOx, and NO2 either simultaneously or in sequence.The measuring range of chemoluminiscence analysers used for emission measurements extends from 10 mg/m3 to 20.000 mg/m3.Interference due to carbon dioxide (CO2) in the sample gas is possible, particularly in the presence of water vapour, due to the quenching of thechemoluminscence. The extent of the quenching depends on the CO2 and H2O concentrations andthe type of analyser used. Any necessary corrections shall be made to the analyser output either byreference to correction curves supplied by the manufacturers or by calibrating with gases containing approximately the same concentration of CO2 as the sample gas.Non-dispersive infrared (NDIR) methodThe most common application of the IR method are analysers working according to the NDIR method. Gases which consist of molecules of different atoms absorb light of the characteristic wavelength in the infrared spectral region.With the NDIR method, spectral analysis of the IR radiation is omitted and the total absorption of the NO molecule at max= 1.876 cm-1 (= 5,3 4m) is used for the measurement.Figure C.3 shows an example of a typical NDIR analyser."Key1 Sample inlet2 Sample pump3 Magnetic valve4 NOx: NO converter5 Flow regulator6 Pressure regulator7 Reaction camber8 Photomultiplier9 Electronics10 Oxygen inlet11 Pressure regulator12 Ozone regulator13 Ozone filter14 Signal15 BypassFigure C.2 Example of an arrangement of a chemoluminescence analyserPage 32EN 1:1998 BSI 2007The radiation emitted from the IR source is divided into two beams and then modulated, one beam passing through the measuring cell and the other through the reference cell containing an IR inactive gas, usually nitrogen. If the sample gas contains NO, some of the IR energy is absorbed and the difference in IR energy reaching the detector is proportional to the amount of NO present. The detector is designed so that it is only sensitive to theNO-specific wavelengths.!A special arrangement of the NDIR method is the gas filter correlation method.Interference is possible, particularly with water vapour.Other methodsBeside the two methods mentioned above there arethe Non-dispersive ultraviolet (NDUV) method andthe Nonextractive (in situ) method. These methods are described in detail in ISO 10849.Annex D (normative)Measurementoftotalhydrocarbons (THC)D.1 General objective and applicabilityThis method is intended to determine the total hydrocarbon content in flue gases from appliances burning solid fuels. The method uses an instrumentequipped with a flame ionisation detector (FID). The measurement is continuous. The result obtained is expressed as equivalents of a reference substance, usually methane or propane. The measurement concerns only the total hydrocarbon content anddoes not give any information of separate constituents.D.2 General procedureThe measurement is extractive, i.e. the test gas flowis drawn from the measuring point and is analysed in a freestanding instrument. The measuring point shall be in the centre of the flue gas pipe and beplaced three diameters after the flue gas outlet of the appliance. If there is a damper or any other device which will give rise to inhomogenities in the flow the measuring point shall be moved to aposition where the flow is homogenous. The measuring system shall be heated to 195 C.D.3 EquipmentThe measuring system consists of the following components: Instrument with flame ionisation detector, FID. Measuring range, usually between 010 and 0100 000 ppm. The instrument shall beequipped with a heated filter. Gas probe with a filter for particulates. The probe shall consist of a suitable material, such ascorrosion resistant steel. The filter shall be heatedso that condensation is avoided. This requires atemperature in the filter of 195 C. Sample line. The sample line shall be heated to the same temperature as the filter. The inner lineshall be of PTFE and be exchangeable. The sample line shall be as short as possible."Key1 Light source2 Chopper motor3 Copper wheel4 Measuring cell5 Reference cell6 Detector7 Electronics8 SignalFigure C.3 Example of a NDIR analyserPage 33EN 1:1998 BSI 2007Annex ZA (informative) !Relationship between this European Standard and the Essential Requirements of EU Directive 89/106/EEC, EU Construction Products DirectiveZA.1 Scope and relevant characteristicsThis European Standard has been prepared under Mandate M/129 Space heating appliances given toCEN by the European Commission and the European Free Trade Association.The clauses of this European Standard shown in this annex meet the requirements of the Mandate given under the EU Construction Products Directive (89/106/EEC).Compliance with these clauses confers a presumption of fitness of the construction products covered by thisannex for their intended uses indicated herein. reference shall be made to the information accompanying the CE marking.WARNING: Other requirements and other EUDirectives, not affecting the fitness for intended use can beapplicable to the construction products falling within the scope of this standard.NOTE 1In addition to any specific clauses relating to dangerous substances contained in this standard, there may be other requirements applicable to the products falling within its scope (e.g. transposed European legislation and national laws, regulationsand administrative provisions).
