How to Calculate Industrial Boiler Coal Consumption
Before purchasing coal fired industrial boilers, many customers want to calculate the amount of coal used in boilers, because this is directly related to the cost of boiler operation. How to calculate industrial boiler coal consumption? Take a steam boiler for example, its coal consumption is related to the operating load: coal consumption (kg) = steam (ton) x The steam enthalpy (kcal / kg) X1000 /[coal calorific value (kcal / kg) x boiler thermal efficiency].
It can be seen that the calculation of industrial coal fired boiler coal consumption needs: thermal efficiency, how much steam needs to be generated and coal calorific value.
From the empirical data, 1 tons coal can produce 6.5 ton to 7.2 ton steam, and 1 ton steam coal consumption can be 120 to 150Kg. In general, coal consumption = boiler heat absorption / (low calorific value of coal * boiler efficiency). Regarding the heat absorption of the boiler, it should be noted that the hot water boiler is generally rated heat load; the steam boiler is boiler tonnage * (steam temperature corresponding to the calorific value - feed water enthalpy value).
All the above methods for calculating the coal consumption of industrial boilers are based on the "Thermodynamic Calculation Method of Industrial Boilers". If you have any questions, welcome to consult our online customer service or Email [email protected].
