What is a boiler explain the working of Babcock boilers?
Babcock and Wilcox Boiler was discovered by George Herman Babcock and Stephen Wilcox in the year 1967. This is a water tube boiler, used in steam power plants. In this type of boiler, water is circulated inside the tubes and hot gases flow over the tubes.
In which condition Babcock and Wilcox boiler can be used?
The Babcock and Wilcox boiler are generally used to produce high-pressure steam in power generation industries. The high-pressure steam so generated is used to produce electricity.
What is maximum working pressure of Babcock and Wilcox boiler?
Clarification: The maximum working pressure of a Babcock and Wilcox boiler is 40 bar. Babcock and Wilcox is used when pressure above 10 bar and steam capacity greater than 7000 kg/hr is required. It is a water-tube boiler.
What is the specification of Babcock and Wilcox boiler?
Specifications of Babcock and Wilcox Boiler: The diameter of drums = 1.22 to 1.83 m. Length = 6.096 to 9.144 m. Size of super-heater tubes = 3.84 to 5.71 cm. Steaming Capacity = 40000 kg / hr (max).
What is pass in boiler?
Each set of tubes that hot combustion flue gas travels through before making a turn within the boiler, is considered a “pass.” A four-pass boiler design consists of four sets of horizontal tubes, with the stack outlet at the front of the vessel.
What type of boiler is Babcock and Wilcox?
water tube boiler
Babcock and Wilcox Boiler was discovered by George Herman Babcock and Stephen Wilcox in the year 1967. This is a water tube boiler, used in steam power plants. In this type of boiler, water is circulated inside the tubes and hot gases flow over the tubes.
What purpose do baffle plates serve in a Babcock and Wilcox boiler?
Explanation: The baffle plates are provided to direct the flow of hot gases around tubes containing water. The water absorbs the heat from the hot gases and the temperature of hot gases is dropped.
What purpose do baffle plate serve in a Babcock and Wilcox boiler?
What is the function of mountings?
Function: To put off the fire in the furnace of the boiler when the level of water in the boiler falls to an unsafe limit and thus avoids the explosion which may place due to overheating of the furnace plate.
What is the objective of providing baffles in between water tubes in the Babcock Wilcox boiler?
The baffles are provided in the way, which deflects the flue gases before escaping from the chimney. Due to this deflection, the flue gases pass more than one time through water tubes, which cause more heat transfer.
