INTRODUCTION OF BOILER
A boiler is a closed vessel in which water or other fluid is heated.
The heated or vaporized fluid exits the boiler for use in various processes or heating applications.
The pressure vessels in a boiler is usually made of steel .
The source of heat for a boiler is combustion of any of several fuels, such as wood, coal, oil or natural gas.
STREM GENERATION THROUGH BOILER
A water tube boiler is a type of boiler in which water circulates In tubes heated externally by the fir.
Fuel is burned inside the furnace creating hot gas which heats water in the steam-generating tubes.
The heated water then rises into the steam drum.
the steam will reenter the furnace through a superheaterto become superheated.
