  • Conversion of Existing Coal-Fired Boilers to Natural Gas Firing

    Converting a boiler to natural gas typically decreases boiler efficiency because of the large quantity of hydrogen in natural gas. During combustion, the hydrogen is converted to water. Evaporating this water uses a portion of the flue gas energy, thus, lowering boiler efficiency. This efficiency loss is offset somewhat by the lower amount of excess air required to burn natural gas. Boiler efficiency decreases are to be expected in the 3% to 4% range, depending on the current fuel and boiler design. Auxiliary power demand is reduced with natural gas firing …Get Price
