While the pulverized coalfired boiler represents the most efficient type of coalfired power plant, there are alternatives. One of these is the fluidized bed boiler. This type of combustion system is capable of burning a much wider range of fuels than a PC plant.
coal was performed in order to examine the environmental aspects of current and future pulverized coal boiler systems. Three systems were examined: 1) a plant that represents the average emissions and efficiency of currently operating coalfired power plants in the (this tells us about the status quo),
the air from the PA fans is routed around the air preheaters and is used as tempering air for the pulverizers. Preheated air and tempering air are mixed at each pulverizer to obtain the desired pulverizer fuelair mixture outlet temperature. The pulverized coal and air mixture flows to the coal nozzles at the various elevations of the
