Diesel Consumption of a Steam Boiler

Steam boilers are mostly used in various types of processing plants, such as food plants, chemical plants, pharmaceutical plants, power plants, starch plants, washing plants, etc. hot water boilers are mostly used for heating and heating, such as hospitals, schools, Troops, hotels, communities, shopping malls, office buildings, family homes, etc.

Fuel oil boilers can generally use diesel and other light oils and heavy oils as raw materials. Generally, light diesel boilers are more common, and the calculation is based on diesel; fuel boilers can be divided into diesel steam boilers and diesel hot water boilers according to different media Use the following formula to calculate:

Fuel consumption per hour for diesel boilers = 3600 * thermal power / heat value / boiler efficiency

The thermal efficiency of a 2-ton oil-fired boiler is 1.4MW, and its combustion calorific value is 42.42Mj / kg. The general efficiency of the ZOZEN oil-fired boiler can reach 90%. Then the following editor will use the 2-ton diesel boiler as an example. The 2-ton diesel boiler the fuel consumption = 3600s * 1.4MW / 42.42Mj / kg / 90% = 132kg

Of course, we can also calculate through some variable parameters:

Oil-fired boilers have become the mainstream product of choice for companies because of their environmental protection and cleanness, and easy fuel supply. However, how to calculate the fuel consumption of oil-fired boilers is related to the company’s operating costs.

Fuel steam boiler:

The fuel steam boiler is also a diesel steam boiler. The hourly steam output D1 = 500 kg; the rated steam pressure is 1.0 MPa, and the saturated steam pressure gauge checks 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

Diesel hot water boiler:

Fuel consumption calculation formula: G = hot water effluent * (heat enthalpy of outlet water-enthalpy of inlet water) / (low heating value * thermal efficiency), low heating value of diesel = 42652kj / kg; low heating value of gasoline = 43062kj / kg ; Low-level heating value of crude oil / heavy oil = 44833kj / kg; Low-level heating value of residual oil = 37646kj / kg;
