Babcock and wilcox boiler ppt12/31/2022 The water level must be carefully watched during the operation of the Babcock and Wilcox boiler.Called high pressure boilers. In the case, if feed water is not continuously supplied even for a short period of time, the boiler gets overheated. A continuous supply of feed water is required for working. That’s why water treatment is must before feeding into the boiler. In the case of impure and sedimentary water, the scale may deposit in the tubes and this leads to overheating and bursting of tubes. It is not much suitable for impure and sedimentary water.Inspection of this types of boiler can be done anytime during its working.It is the only boiler that is used to generate a large quantity of heat in power stations. Replacement of defective tubes is easy.The high-pressure steam so generated is used to produce electricity. The Babcock and Wilcox boiler are generally used to produce high-pressure steam in power generation industries. The superheated steam from the steam stop valve is either collected in a steam drum or made to strike on the steam turbine for electricity generation in the steam power plant.įor Better Explanation of Working of Babcock and Wilcox Boiler, Watch the Video Given Below:.It increases the temperature of the steam to the desired level and transfers it to the steam stop valve. The superheater receives the water-free steam from the anti-priming pipe.This anti-priming pipe filters the water content from the steam and allows only dry steam to enter into the superheater. An anti-priming pipe is provided in the drum.The steam generated is moved upward and through uptake header, it gets collected at the upper side in the boiler drum.As the hot flue gases come in contact with water tubes, it exchanges the heat with water and converts it into steam.The coal-burning on the grate produces hot flue gases and it is forced to move in a zigzag way with the help of baffle plates. The water present in the inclined water tubes gets heated up by the hot flue gases.First, the water starts to come in the water tubes from the drum through down take header.Now let’s discuss the working of Babcock and Wilcox boiler step by step. It opens and releases the extra steam in the environment to maintain the desired pressure within theīoiler.
