### Boiler specifications

• Coal: Imported (South African / Indonesian)
• Coal HHV: 6100 kcal/kg (approx)
• Coal LHV: 5900 kcal/kg (approx)
• Steam Pressure: 32 barA
• Steam Temperature: 400 C
• Steam flow: 40 tph

### 40 tons of coal-fired boiler fuel consumption

Coal consumption 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 coal fuel with a minimum calorific value of 5,500kcal/kg as an example, it is assumed that the thermal efficiency of the boiler is generally about 80% (ZBG boiler manufacturer CFB boiler can currently be used. The combustion efficiency is about 92%, 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. 40t coal-fired boiler fuel consumption=136kg/hX40t=5440kg/h

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

As a 78-year-old industrial boiler manufacturer, ZBG not only provides coal-fired boilers, but also biomass boilers, oil-fired gas boilers and waste heat boilers.
