The Combustion system converts energy in coal to Heat. Water and steam system converts the heat to steam at high pressures and temperatures. This series explains the working of the boiler in modern power plant. How does a Power Plant Boiler work? – Water and Steam System.
This invention relates to the combustion of coal and particularly to a method and apparatus for the combustion of pulverized coal. Systems utilizing pulverized coal, as heretofore known and used, are open to numerous objections such as high cost, limitations upon the kind of fuel usable therein, and nonuniformity and general difficulty in operation.
Dec 16, 2013· Abstract: The present invention relates to a process for reducing coal consumption in coal fired plant with fluidizedbed drying, namely a fluidizedbed drying system is provided between a coal powder bunker as well as a weighing belt and a coal grinding mill of the prior coal fired boiler generating set, and superheated steam which has done ...

The coal is to be burned in a boiler at 12% excess air to raise 150,000 lbm/hr of 120 psia steam using inlet water at 46°F. If the boiler efficiency is 83%, find: (a) HHV, (b) coal firing rate in lbm/hr, and (c) the air flow rate in cfm entering the boiler at 55°F.
Driver's duties. Controls on the driver's side of the footplate. Not visible in the photo, because they are down by the floor, are the rail sanding gear and cylinder drain cocks (see text for details) The regulator is the 'throttle' of the locomotive; it controls the delivery of steam from the boiler into the cylinders.
