Babcock & wilcox boiler harshil • 1. Present by: Mehta Harshil Enrollment no: 07 Electrical department GEC MODASA • General: This boiler is used when pressure is above 10 bar Capacity: 7000 kg of steam/hr It is used to operate high pressure. • Characteristics of Boiler Horizontal boiler Water – tube boiler Stationary boiler Externally boiler Multiple tube boiler Natural circulation boiler High pressure boiler • Specification of boiler Diameter of drum: 1.22 to 1.83 m Length: 6.096 to 9.144 m Size of water tube: 7.62 to 10.16 cm Size of superheated tube: 3.84 to 5.71 cm Maximum working pressure: 41 bar Maximum steaming capacity: 40,000 kg/hr Efficiency: 60 to 80% • This headers are connected to a inclined water tubes. The water tube inclined to the horizontal about 15ansh.
The baffles plate are provided in order to make circulation of hot gases in sine waves form. A damper is fitted at back of the boiler to regulate draught. • The damper control the flow of air into the furnace. Water is heated by hot gases coming from furnace.
Due to heating of water density of water decreases. Low density water move upwards in water tube and finally water converted into the steam. This cycle repeat continuously. The steam flows in super heater tubes and is finally taken out through the main steam stop valve and supplied to the engine when needed in the end of the process mud collector is provided to remove the mud particles through a blow down cock. It uses both solid as well as liquid fuel for burning.
