What is the fuel consumption of a 4 ton oil-fired hot water boiler in one hour? This needs to be calculated using a calculation formula. We calculate according to fuel oil hot water boiler: fuel oil hot water boiler fuel consumption per hour = 3600 * thermal power / calorific value / boiler efficiency.
The thermal efficiency of a 4-ton oil-fired hot water boiler is 2.8MW, and its combustion calorific value is 42.42Mj / kg. The general efficiency of an oil-fired hot water boiler can reach 90%. Fuel oil hot water boiler fuel consumption = 3600s * 2.8MW / 42.42Mj / kg / 90% = 198kg.
Of course, we can also calculate by some variable parameters: the fuel oil hot water boiler is the mainstream product selected by the enterprise because of its environmental protection and cleanness, and the fuel supply is convenient. cost.
Fuel oil hot water boiler fuel consumption:
The hourly steam output of the oil-fired hot water boiler is D1 = 500 kg; the rated steam pressure is 1.0 MPa. Check the saturated steam pressure gauge to get the fuel steam enthalpy i2 = 2771.1 kJ / kg at this working pressure. Under normal circumstances, the boiler feed water temperature is 20 ℃, then the feed water heat enthalpy i1 = 83.74 kJ / kg; 0 # light diesel low calorific value Q = 10100 kcal / kg = 42420 kJ / kg; boiler thermal efficiency ζ = 0.93. Hourly fuel consumption B1 = D1 (i2-i1) / Q • ζ = 500 × (2777.1-83.74) /42420•0.93
Fuel oil hot water boiler fuel consumption calculation formula: G = hot water effluent * (exhaust heat enthalpy-inlet water enthalpy) / (low heating value * thermal efficiency), diesel low heating value = 42652kj / kg; gasoline low heating value = 43062kj / kg; crude oil / heavy oil low calorific value = 44833kj / kg; residual oil low calorific value = 37646kj / kg
Although the calculation methods are different, the results are not much different.
