Converting coal-fired boilers to gas-fired boilers

The transformation cost is an important data to measure whether the coal-fired boiler has transformation value. Our Fangkuai boiler takes the transformation of a coal-fired boiler to a gas-fired boiler as an example to briefly explain the transformation cost for everyone.
It is difficult for many customers and friends to obtain some detailed structure and detailed data such as fuel cost and calorific value, and customers need to do some work on the efficiency and cost of coal-fired boilers before and after the transformation of coal-fired boilers with the assistance of Zhengzhou Fangkuai boiler engineers. estimate.
Ideally, for saturated steam boilers or hot water boilers, thermal accounting is not required to maintain the original working pressure and power.
And to estimate the fuel consumption, choose the burner fan or choose the integral burner, a simple estimation of the following formula can be made:
Burner power (KW) = boiler power (KW) / boiler thermal efficiency (%);
Fuel consumption calculation method: boiler fuel consumption = burner power / fuel calorific value;
If there is no specific reference fuel calorific value data, you can refer to these fuel calorific value values:
Light diesel 11.86kg/h, natural gas 9.88m3/h, liquefied petroleum gas 25.58m3/h, city gas 4.42m3/h.
If the calorific value of the fuel is already known with certainty, the known data must be used.
In addition, it is necessary to know that after the coal-fired boiler is changed to a gas-fired boiler, the thermal efficiency of the boiler will be greatly improved.
