The appliance is installed in a calorimeter room with the flue exhausting into a dilution tunnel. It is fired in a given manner, and particulate emissions are sampled from the dilution tunnel and measured over a number of different burn cycles. The emission rate for each burn cycle is calculated, and the results averaged to obtain the appliance particulate emission factor.
Apparatus for the collection of emissions (see Figure 2.1). This shall include the following components:
(a) Sample probe A 450 mm long seamless stainless steel or glass probe of nominal internal diameter 9.5 mm with one end cut off at right angles, as shown in Figure 2.1.
(b) Filter holders Two 50 mm nominal diameter filter holders.
(c) Temperature measurement A system for measuring the sample gas temperature in the range 10°C to 40°C with an accuracy of±2°C.
(d) Drying system Equipment capable of reducing the moisture content of the sample gas to less than 1.5% moisture by volume.
(e) Dry gas meter A suitable instrument for measuring dry gas volume of a sample with a calibrated accuracy of±1% of the volume sampled.
(f) Sampling gas temperature measurement A system for measuring the average temperature of the sampling gas passing through the dry gas meter over the range 10°C to 40°C to within±2°C.
(g) Filters Glass fibre filters of 50 mm nominal diameter to fit the filter holders, without organic binders and having at least 99.95% collection efficiency on 0.3 μm dioctyl phthalate smoke particles.
(h) Pump A pump that is capable of extracting the gas sample at the required rate against the resistance imposed by the sample probe, filters, dryer and connecting tubes.
(i) Dilution tunnel Apparatus as shown in Figure 2.2，and including the following components:
(i) A temperature system For measuring the temperature in the dilution tunnel over the range 10°C to 200°C with an accuracy of±2°C.
(ii) Pitot tube A Type‘S’ or standard Pitot tube of a known coefficient.
(iii) Differential pressure gauge A pressure measuring device for measuring the Pitot tube velocity head to within±1 Pa.AS NZS 4013 pdf free download.
