  • Best Gas Fuel Fired Boiler - butyesklep.pl

    Natural Gas Fired Boilers. The boiler efficiency is usually reduced to 84-85%, when a coal fired boiler is converted to natural gas. The biggest change is due to the combustion of Hydrogen. This is normally a 4% heat loss while firing coal and about a 11% heat loss while firing natural gas.Learn More
