SUGAR LAND, TEXAS--April 6, 2017--Researched by Industrial Info Resources (Sugar Land, Texas)--Coal-fired power plants have been closing across North America due to more stringent environmental regulations over the last few years. But plant owners are also looking to keep facilities operational by converting them to use alternative fuel sources, such as natural gas and biomass, if it proves economically feasible. At many older coal-fired power plants, the cost to convert a boiler to use an alternative fuel is much less than installing expensive and more stringent environmental controls.
