  • How to Calculate Gas Consumption in a Gas Boiler Burner?

    Mar 20, 2019 · However, Gas boiler burners are not 100-percent efficient. If you know the burner efficiency, you can calculate the exact fuel consumption per the output of the burner. If you do not, you will have to use an approximation. LP gas and natural gas contain different amounts of energy, so the conversion factor is different. Approximate Gas Learn More

  • Oil & Gas Fired Boilers - Thermaxglobal

    Maximum efficiency is obtained generally when a boiler is used at 65-75% of load. 1 When the load of the boiler falls below 50%, in order to burn all of the fuel, more excess air should be fed and this will increase heat losses. Therefore, a boiler load which is under 50% is not suitable in terms of efficiency. 3.Learn More
