What is the coal consumption of one set of 10tph coal-fired steam boiler?

28 Jan 2023

The coal-fired boiler uses coal as fuel. The boiler coal consumption calculation is a key factor to measure the efficiency of boilers. Under the same condition, the coal-fired boiler with less boiler coal consumption calculation can save more costs for enterprises. However, the coal consumption of coal-fired boilers is related to many factors, such as the efficiency of the boiler, the calorific value of fuel coal and the degree of coal combustion.

The calculation formula of the coal consumption of coal-fired boilers:

Coal consumption = boiler capacity × 3600 / calorific value of coal combustion / boiler efficiency

Assuming the calorific value of coal is 5000 kcal, it can be calculated:

The coal consumption of a 1tph coal-fired boiler is 133kgs/hour

The coal consumption of a 2tph coal-fired boiler is 238kgs/hour

The coal consumption of a 4tph coal-fired boiler is 447kgs/hour

The coal consumption of a 10tph coal-fired boiler is 1850kgs/hour

 

At present, different provinces and cities in China have different remediation policies for coal-fired boilers under 10 tons, 20 tons and 35 tons, but the transition trend from small boilers to large boilers is irreversible. The so-called energy-saving and efficient coal-fired boilers, such as large-scale circulating fluidized bed boilers and large-scale corner tube boilers, are all high-efficiency equipment promoted by the state, with low emissions, high efficiency and mature technology.

 

The boiler coal consumption calculation of coal-fired boiler = heat required by boiler/calorific value of coal/thermal efficiency of boiler

 

For example, the heat required for a 1-ton coal-fired boiler is 600,000 kcal/hour. Taking the coal fuel with the lowest calorific value of 5500kcal/kg as an example, assuming that the thermal efficiency of the boiler is generally about 80% (the current combustion efficiency of ZOZEN CFB boiler is about 89%, which is comparable to the national standard efficiency of gas-fired boilers), then the coal consumption per hour of a 1-ton coal-fired boiler is: 600000kcal/h÷5500kcal/kg÷80%=136kg/h.

 

It can be seen that how much fuel a coal-fired boiler consumes per hour in a day depends on many factors. If the selected fuel has high calorific value and high boiler efficiency, the fuel consumption of the boiler will definitely be low, otherwise it will increase the fuel cost of the boiler operation. In addition, the more complex the boiler, the more factors that affect fuel consumption.
