Gas and multi-fuel power plants - Wärtsilä

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

Natural Gas Fired Boilers

Oct 17, 2016 · Steam or hot water boilers – condensing water requires reducing the flue gas temperature low enough where acids present in the flue gas will also condense out and cause stack corrosion and potential failure. Using a fuel consumption on an LHV basis with a HHV gas price can lead to a significant underestimation of fuel costs.
