Boiler Efficiency - an overview | ScienceDirect Topics

For every 20°C decrease in the gas outlet temperature of the air heater the boiler efficiency rises about 1% with inherent fuel consumption reductions. It has been observed worldwide that leakage rates of more than 30% are not uncommon while rates of 15%20% are typical.

How to Calculate Gas Consumption in a Gas Burner | Hunker

Adjust for the burner efficiency by dividing consumption at 100 percent efficiency by the burner efficiency rating. For a burner that is 95-percent efficient divide by 0.95. In the example: 40000 BTU divided by 1075 = 37.21. Adjusting for burner efficiency: 37.21 divided by 0.95 = 39.17 cubic feet of natural gas consumed in one hour.

How to calculate the gas consumption of the gas boilers ...

How to calculate the gas consumption of a gas boiler? Gas consumption = Gas boiler power /Fuel calorific value / Gas boiler heat value utilization. For example we operate 1 ton gas boiler for 1 hour (full load). The boiler output is 600000 kcal (fixed value) the natural gas calorific value is 36.22 MJ/Nm3 (fixed value) and the thermal efficiency is 92% (non-fixed value).
