Conversion of Existing Coal-Fired Boilers to Natural Gas

Challenges when Converting Coal-Fired Boilers to Natural Gas by Stephen Black Senior Engineer Fuel Equipment Design air and flue gas flow rates, heat transfer through sections, boiler efficiency, attemperator flow, and tube metal temperatures. This paper will address these considerations and draw on examples for the effect of OFA on the

In coal-fired power plant boilers a lot of production problems are generated due to fouling. Lack in timely maintenance and cleaning can also lead to fouling problem [45] .

The boiler efficiency of modern pulverized fuel, hard coal-fired units is 94%–95% (LHV basis), reducing slightly to 90%–91% for lignite-fired units due to the higher moisture content. When combined with the other elements of the Rankine cycle, the overall efficiency currently achievable in conventional plants is in the 40%–45% range.

cracker furnaces, nitric acid plants, catalyst manufacturing processes, nitrogen fixation processes, and solid/liquid or gas waste incinerators [2, 3]. In the U.S., SCR has been installed on more than 300 coal-fired power plants ranging in size from less than 100 megawatt equivalent (MWe) to 1,400 MWe [1, 4].
