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. When firing natural gas, other losses such as dry gas loss, moisture in fuel and

Understanding Wood Boiler Efficiency and EPA Ratings

2021/8/10 · If wood boiler efficiency is reported at 99%, it is almost certainly combustion efficiency. 99% efficiency is likely not indicative of how much heat is being transferred from the fuel water for heating. There are multiple test methods. US test methods will result in lower reported efficiency than European test methods.
