Summary of Test Method
37、84.1 This test method is used in conjunction with TestMethod E2515. The wood heater under evaluation is fueled bycordwood test fuel loads. Test runs employ either a hot-to-hotcycle or a cold-to-hot cycle depending on the burn ratecategory of the test run. The test fuel pieces must be within theallow
38、able range of specific gravity. The test fuel load weightand composition is determined based on the usable fireboxvolume of the heater. For low and medium fire test runs, acharcoal bed is established by conducting a full high fire testrun. That high fire test run may be an actual test run or may bej
39、ust for the purpose of establishing the charcoal bed for a lowor medium fire test run. The test fuel load is placed on thecharcoal bed and given time to ignite before the air control(s)is (are) set to the test run condition.4.1.1 For the low and medium fire test runs, particulateemission sampling an
40、d efficiency measurements begin imme-diately prior to addition of the test fuel load to the firebox andend when the test run is terminated in accordance with thespecifications in the method.4.1.2 For the high fire test runs, the test run for the purposesof determining emission rate or emission facto
41、r begins with acold (see 8.5.1) empty (see 8.2.1) firebox. Kindling (andcrumpled newspaper, if specified) are used to ignite start-upfuel pieces which, in turn, are used to ignite the test fuel loadfollowing manufacturers written instructions. Particulateemission sampling begins before the kindling
42、is ignited andends when the test run is terminated in accordance with thespecifications in the method.4.1.3 For low fire, medium fire, and high fire test runs,efficiency is determined on a hot-to-hot cycle and efficiencyparameter measurements begin when the test fuel load is addedto the firebox and
43、end when the test run is terminated inaccordance with the specifications in the method.4.1.4 For low fire, medium fire, and high fire test runs,average burn rate is determined on a hot-to-hot basis and isbased on the weight of the portion of the test fuel load burnedduring the test run divided by th
44、e duration of the test runbeginning when the test fuel load is added to the firebox andending when the test run is terminated. Burn rate for all testruns is adjusted to a dry fuel weight basis.4.1.5 The total particulate emissions are determined overthe test run duration. The particulate emissions r
45、ate is thendetermined from the total particulate emissions divided by theduration of the test run and is reported in grams of particulateper hour. The test run duration for the high fire test for purposesof determining particulate emission rate includes the kindlingand start-up fuel period before th
46、e test fuel load is added to thefirebox. The particulate emission factor lb/lb (g/kg) also maybe determined from the total particulate emissions divided bythe dry basis weight of the total fuel weight burned and isreported in pounds of particulate per dry pound of fuel (gramsof particulate per dry k
47、ilogram of fuel). For high fire test runs,the total test fuel weight when determining emission factorincludes any kindling and start-up fuel consumed before thetest fuel load is added less any fuel remaining at the end of thetest run.4.1.6 This test method also may be used in conjunction withAnnex A
48、1 and CSA B415.1 for determining heat output andefficiency. If heat output and efficiency are determined, par-ticulate emissions per unit of heat output also may be calcu-lated and is reported in pounds of particulate per million Btu ofheat output (grams of particulate per megajoule). For low andmed
49、ium fire test runs, the efficiency, heat output, and particu-late emissions per unit of heat output are determined on ahot-to-hot cycle. For high fire test runs, particulate emissionsare determined for the entire test run, including the cold start(kindling and start-up) portion. However, the kindling andstart-up portions of the test run are excluded from the efficiencyand heat output determination. For the determination of par-ticulate emissions per unit of heat output, a different approachmust be taken. The hot-to-hot
