Natural Gas Fired Boilers - innovativecombustion.com

Depending on a number of factors including coal properties, boiler efficiency typically ranges between 87% and 89% while firing coal. 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
