Emission Standard for Power Plant with Mixed Fuel

In case of a power plant utilizing mixed fuel (mixture of various types of fuel) in each generating unit, emission standard values must be calculated base upon the ratio of each type of fuel as follow:

Emission Standard = A X + BY + C Z

When

A = Emission Standards for utilizing only coal as fuel

B = Emission Standards for utilizing only oil as fuel

C = Emission Standards for utilizing only gas as fuel

X = Ratio of Heat Input from utilizing only coal as fuel

Y = Ratio of Heat Input from utilization only oil as fuel

Z = Ratio of Heat Input from utilization only gas as fuel

In case of an existing power plant utilizing emission stack more than one, emission average values must be calculated base upon the ratio of each emission fkow rate and emission concentration as follow:
Emission Average
Qi= Emission flow rate of stack i from existing power plant, thermal power plant, combine cycle plant, gas turbine power plant or other existing power plant (m3/hr)
Ci= Emission concentration of stack i from existing power plant, thermal power plant, combine cycle plant, gas turbine power plant or other existing power plant as gas (ppm) or participate (mg/m3)
n = Number of stack
i= 1, 2, 3,...n
