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 of combustion

do not :crne ‘Into direct contact with other materials. Fuels include those such as coke, coal, lignite, coke breeze, fuel oH, end wood,

but do not include refuse. When any products or by—products of a manufacturing process are burned fcr the same purpose or in conJunction with any fuel, the same maximum emission limi

tations shall apply.

28.1.2 The heat content of coal shall be determined

according to ASTh method D-2.7l—6 1iLaboratory Sampng and Analysis of Coal or Coke or ASTM • 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 of combustion pass through

a stack or stacks. The heat Input value used

shall be the equipment manufacturer’s or

designer’s guaranteed maximum input, whichever

Is greater. The total heat input of all fuel—

burning units on a plant or premises shailbe

used-for determining the maximum allowable

amount of particulate matter which may be

emitted.

28.1.1, The amount of particulate matter emitted shall

be measured according to the American Society

of Mechanical Enghieers’ Power Test Codes

PTC—27, dated .1957 entitled, “Determining Dust

Concentrations in a G’ Strcm “ ‘4’!ch publi

cation Is made a p If ‘ìi’i .cn by

reference. The Contrti Officer may modify

this testing procedure or specify the use of

more current procedures in accordance with

good professional practice.

of particulate matter from any fuel-burning

equipment in excess of th quantity set forth
