installation and operation. The DF520 boiler is designed for coal firing. When oil is used, it should be used as a backup fuel and not the pri-mary fuel. The DF520 boiler is designed for use with hot water heating systems (30 PSI Max.) and steam heating systems (15 PSI Max.). Do not use or store flammable liquids, especially gasoline, in the vicinity of the boiler. Coal 1.
Natural Gas Conversions of Existing Coal-Fired Boilers
Aug 01, 2011 · Electric utilities are always searching for ways to minimize costs, improve availability, and reduce emissions. If the existing boiler is modified for gas-firing, the convection pass, ducting
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 because pulverizers, primary air (PA) fans, precipitators, coal and ash handling systems, sootblowers, and other equipment are no longer required.
to withstand the side thrust load of the coal. 3. Do not store coal within boiler installation clearances, or within the space required for charging and ash removal. 4.
