In addition to labor costs, water charges, electricity bills, maintenance and repair costs, the cost of boilers accounts for about 90% of the cost of fuel consumption. Therefore, customers are more concerned about the fuel consumption of the boiler.
The boiler's fuel consumption is related to boiler capacity, thermal efficiency, fuel calorific value and other parameters.
Fuel Consumption = Heat Input required (kcal/hr.) / Calorific Value of that fuel (kcal/kg)
Heat Input required (kcal/hr)= (Boiler Capacity) x (Steam Enthalpy - Feed water Enthalpy)) / (Boiler Efficiency)
In general, the parameters of the boiler will give the boiler thermal efficiency, fuel type, steam temperature, feed water temperature, boiler capacity and other parameters. Calorific value(GCV) is the amount of heat liberated in Kcal by the complete combustion of 1 kg of fuel
The natural gas consumption of the ZBG 1 ton wns series steam boiler is 79.4 Nm3/h.
The consumption of shaped biomass pellets with a low calorific value of 750 KJ/kg is 160 kg/h in a 1 ton fast-assembled biomass boiler
