In gasification plants, if more than one fuel is fired simultaneously in a boiler:

1. A. The boiler shall be considered as two or more units, each firing the equivalent amount of fuel with the appropriate heat content separately but having a common stack for determination of allowable emissions.
2. B. Allowable emissions shall be calculated according to the following formula: ET = Eo Qo + Ec Qc + Eg Qg, where ET is the total allowed emission in pounds per given period of time; Eo is the allowed emission from oil in pounds per million BTU's; Ec is the allowed emission from coal in pounds per million BTU's; Eg is the allowed emission from gas in pounds per million BTU's; Qo is the heat released by the oil based on the higher heating value in BTU's per period of time; Qc is the heat released by the coal based on the higher heating value in BTU's per period of time; and Qg is the heat released by the gas based on the lower heating value in BTU's per period of time.

3. C. In addition, the total allowable emissions of particulates two microns equivalent aerodynamic diameter or less shall be calculated according to: Ef = 0.40 Ec (Qo + Qc + Qg) where: Ef is the total allowed emission of fine particulates in pounds per given period of time, and all other terms remain as previously defined.
