Fuel Consumption Calculation

m: Fuel Amount (kg)

n : Yield (%)

Hu: Lower Heating Value of Fuel (kcal/h)

Q : Steam Requirement (kg/h)

i : Steam Enthalpy (kcal/kg) (calculated as ≈600)

m=Q*İ/Hu*n

EXAMPLE 1: 15.000kg/h–8bar FLUIDIZED BED BLISTERED TYPE STEAM BOILER FUEL REQUIREMENT

n:%85

Hu:3000kcal/h

i:600kcal/h m=15000*600 / 3000*0,85=3529,41kg/h

EXAMPLE 2: 15.000kg/h–8bar FLUIDIZED BED CIRCULATION TYPE STEAM BOILER FUEL REQUIREMENT

n:%88

Hu:3000kcal/h

i:600kcal/h m=15000*600 / 3000*0,88=3409,09kg/h

EXAMPLE 3: 15.000kg/h – 8bar TRAVELLING GRATE TYPE STEAM BOILER FUEL REQUIREMENT

n:%75

Hu:4000kcal/h

i:600kcal/h m=15000*600 / 4000*0,75=3000,00kg/h

EXAMPLE 4: 15.000kg/h – 8bar NATURAL GAS STEAM BOILER (WITHOUT ECO) FUEL REQUIREMENT

n:%90

Hu:9000kcal/h

i:600kcal/h m=15000*600 / 9000*0,90=1111,11Nm3/h

EXAMPLE 5: 15.000kg/h – 8bar NATURAL GAS STEAM BOILER (ECO) FUEL REQUIREMENT

n:%95

Hu:9000kcal/h

i:600kcal/h m=15000*600 / 9000*0,95=1052,63Nm3/h

EXAMPLE 6: 5,000,000kcal/h NATURAL GAS BOILER (NO ECO) FUEL REQUIREMENT

n:%85

Hu:9000kcal/h

m=5000000 / 9000*0,85=653,59Nm3/h
