Coal that has been ground into a fine powder by a pulverizer is blown into a furnace-like device, called a boiler, and burned. The heat produced converts water, which runs through a series of pipes in the boiler, to steam. The high-pressure steam turns the blades of a turbine, which is connected by a shaft to a generator.
The boiler generates high pressure steam by transfering the heat of Combustion in various heat transfer sections. This article briefly describes the flow and arrangement of the heat transfer sections in a boiler. In line diagrams help make the concept clear.

Used boilers can be utilized to provide steam or hot water for any industrial plant. Whether electric, or gas fired, fire tube, water tube or commercial a boiler the process where water or oil burns inside the combustion chamber and heats up the heat exchanger, which in turn heats water or oil to provide steam.
The steam leaves the boiler and flows to the high pressure turbine (HP) at a temperature of 535 ºC and ±500kg/Sec. This is called live steam. The boilers are of the reheat design. On returning from the HP turbine, the steam (cold reheat) flows through primary and secondary reheaters, where steam is re-heated to 535 ºC.
In response to this need, the package or shop-assembled boilers were developed.
