SECTION 28

— FUEL BURNING EQUIPMENT
28.1 General Provisions 28.1.1 This regulation applies to instaliatlonsin which fl ; burned forthe primary purpose of produ.ing heat or power by indirect heat transfr in which the products ofcombustion do not :crne‘Into direct contact with other materials. Fuels include those such as coke, coal, lignite, coke breeze, fuel oH, endwood, but do not include refuse. When any products or by—products ofa manufacturing process are burned fcr the same purpose or in conJunction with any fuel, the samemaximum emission limi tations shall apply. 28.1.2 The heat content of coal shall be determined according to ASThmethod D-2.7l—6 1 i Laboratory Sampng and Analysis of Coal or Coke orASTM • method D-2015-62Tgross calorific value of solid fuel by the Adiabatic Bomb Calorimeter, which publicatons are made a part of this • section by reference. 28.1.3 For purposes of this regulation the heat Input shall be the aggregate heat content of all fuels whose products ofcombustion pass through a stack or stacks. The heat Input valueused shall be the equipmentmanufacturer’s or designer’s guaranteed maximum input, whichever Is greater. The total heat input ofall fuel— burning units on a plant orpremises shailbe used-for determining themaximum allowable amount of particulate matterwhich may be emitted. 28.1.1, The amount ofparticulatematteremitted shall be measured according to the American Society ofMechanical Enghieers’ PowerTest Codes PTC—27, dated
