cost comparison of common coal-fired, coke-fired, gas-fired, oil fired boilers, electric boilers and waste heat recovery hot water units, Economic analysis and comparison of operation with daily hot water output of 20 tons

fuel price thermal efficiency one day cost one year total operation cost

coal fired furnace 600 yuan/ton 55% 300 yuan 108000.00

coke fired furnace 1000 yuan/ton 70% 220 yuan 80300.00

gas fired furnace 1.9 yuan/m2 75% 237.5 yuan 86687.50

oil fired furnace 3200 yuan/ton 85% 588 yuan 214912.00

electric boiler 0.7 yuan/degree 97%6 with the help of external Forcefully push the jaw 71.3 yuan 245024.50

hot water unit 0.7 yuan/degree 500% 130.34 yuan 47574.10

it is designed to heat 20 tons of water from the ② closed oil delivery valve to 55 ℃, cold water to 15 ℃, daily and annual cost calculation

1, and operation cost calculation of hot water unit

20000kg 1kcal/kg ℃ 40 ℃ (860 kcal kg/kwh cop5.0) =186.2 kwh

the daily operation cost is; 186.2 kwh 0.7 yuan/kWh =130.34 yuan

the annual operating cost is; 365186.2 kwh 0.7 yuan/kWh =47574.10 yuan

2, calculation of oil fired boiler operation cost

20000kg 1kcal/kg ℃ 40 ℃ (10200kcal/kg/degree thermal efficiency 85%) =92kg/day

the daily operating cost is; 92kg 6.4 yuan/kg =588.8 yuan

the annual operating cost is; 36592kg 6.4 yuan/kg =214912.00 yuan

3, calculation of operation cost of gas fired boiler

20000kg 1kcal/kg ℃ 40 ℃ (8500Kcal m3 thermal efficiency 75%) =125 m3/day

the daily operation cost is; 125 m3 1.9 yuan/m3 =237.5 yuan

the annual operating cost is; 365 125 m3 1.9 yuan/m3 =86687.50 yuan
