1、Designation: E2817 11Standard Test Method forTest Fueling Masonry Heaters1This standard is issued under the fixed designation E2817; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses
2、 indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method covers the fueling and operatingprotocol for determining particulate matter emissions fromsolid fuel biomass (cordwood or other densified,
3、binder freebiomass fuels) fires in masonry heaters. It may also be used totest other similar appliances (see 3.2.20).1.2 This test method is applicable to the operation andfueling of masonry heaters during particulate emissions mea-surement test periods. The prescribed methods and proceduresof these
4、 protocols are performed on masonry heaters installedand operated in accordance with the builder or manufacturersspecifications.1.3 In conjunction with Test Method E2515, this testmethod provides a protocol for laboratory emissions testing ofmasonry heaters that is intended to simulate actual use in
5、residential homes and other consumer applications. Since suchactual use involves almost solely cordwood fueling,AnnexA1,Cordwood Fuel, provides as close a simulation as is currentlypossible of consumer use, and is recommended for predictingactual consumer emissions performance. For regulatory andoth
6、er potential uses in comparing relative emissions of variousmasonry heater products and designs, Annex A2, CribwoodFueling, and Annex A3, Cribwood Fuel, Top-Down Burn,provide optional additional fueling protocols that substitutedimensional lumber cribs for the cordwood fuel. Data thatestablish the r
