Boiler
At present, oil fuel for boiler is being sold much higher than the oil fuel sold through gasoline station. Above price of Solar listed at the gasoline station at Rp1,650 per liter is for public use and the same solar fuel for industry are being distributed through different channels by the government Pertamina at about Rp2,100-/per liter.(Solar=Diesel Oil)

Fuel Consumption ( 1 ton steam )
Q = 1000 Kg/hr heat output
T = 179 deg.C saturated steam
P = 10 Kg/cm2 steam pressure
Tf = 100 deg C. feedwater temperature
hs = 663 Kcal/Kgtotal heat of steam
hf = 65 Kcal/kgheat from feedwater
Hv = 5700 Kcal/kgLow calorie coal a.r.
Hv = 6200 Kcal/kgHigh calorie coal a.r.
Eff= 0.8 Boiler efficiency
Fc = Heat output x (total heat - heat in water)
Eff x Fuel heating Value
Fc = Q x (hs-hf)
Eff x Hv
LOW CALORIE COAL CONSUMPTION
Fc = 1000 X (663 - 65)=131.14 Kg
0.8 x 5700
HIGH CALORIE COAL CONSUMPTION
Fc = 1000 X (663 - 65)=120.56 Kg
0.8 x 6200
