How To Calculate Natural Gas Boiler Consumption--ZBG

The boiler gas consumption calculation need the following parameters: such as natural gas calorific value 8500kcal/m3 pressure 8-10Kpa and theoretically the gas consumption of boiler heat = boiler calorific value÷ (Calorific value of natural gas x Boiler thermal efficiency)= 2400 000 Kcal / (8500Kcal * 0.94) =297m3/h here we take 4 tons of natural gas boilers for example then the boiler gas

How to improve boiler efficiency by evaluation ...

Dec 24 2019 · steam fuel ratio (SFR) in Boiler: from this equation steam fuel ration is =1500/110=13.63 Kg/kg. In practice in the field the key performance indicator is the SFR (Steam fuel ratio). If steam fuel ration is high then it is considered that the boiler is more efficient. An idle boiler performs at 84 to 86 % of the efficiency So the steam fuel ration can the calculated accordingly.

Calculate the combustion-air mass required to burn the 20 gallons of No. 6 fuel oil above. Since the air-fuel stoichiometric ratio is 14.4 pounds of air per pound of fuel the boiler's burner would need 20 gallons x 7.95 lb/gal for No. 6 fuel oil or 2289 pounds of air to burn the oil. This would in turn yield a total flow of 2628.1 lb/hr of steam.
