Working Principle of Babcock and Wilcox Boiler: The working of Babcock and Wilcox boiler is first the water starts to come in the water tubes from the drum through down take header with the help of a boiler feed pump which continues to feed the water against the drum pressure.
So this is named as Babcock and Wilcox.Babcock and Wilcox is a stationary water tube boiler. Steam flows from the drum to the super heater, where it heated by the flue gases and send for the process work.Baffles are provided between the water tubes. The angle of inclination of the water tubes to the horizontal is about 15 degrees. In this boiler, water will flow from the drum by means of tubes only.It is the platform in the furnace upon which fuel is burnt.It is a chamber formed by the space above the grate and below the boiler shell in which combustion takes place.The baffles are provided to deflect the hot flue gases so that the water tubes experience more amount of heat.All the impurities which are present in the boiler are deposited at the om and are stored in the mud box.They are provided for cleaning and inspection of the boiler.It is the volume of a shell that is covered by water.The volume of shell except, the volume of water and tube space is called Steam space.It is the indicator, which shows the level of water in the shell.Mohammed Shafi is the Founder of Mechanical Students. It transports the steam from the water tubes to the drum.They are the tubes in which water flows and gets converted into steam. The high pressure steam so generated is used to produce electricity.Pankaj Mishra is a blogger by passion and Mechanical Engineer by profession. It is inclined at angle of 10-15 degree with the horizontal direction. If you have any query, asks by commenting. Water flows from the drum to the tubes.Steam separator drum and water tubes are connected by the two tubes. 2. This boiler is exclusively used when pressure is above 10 bar and capacity requirement is in excess of 7000 kg of steam/hr. The works are to measure the pressure of the steam.The safety valve is to prevent an increase in steam pressure.The steam stop valve regulates the supply of steam outside to the boiler.First, from the boiler, the steam generated comes to an anti priming pipe here some parts of water particles will be removed and it completely remains dry steam then further this steam is used for needed place.Manhole is a very important part of the boiler. Due to its inclination the water tubes do not completely filled with water and the water and steam separated out easily.Baffle plates are present in between water tubes and it allows the zigzag motion of hot flue gases from the furnace.It is used to ignite the solid fuel in the furnace.It is a base on which the burning of the solid fuel takes place.It is present at the bottom of down take header and used to collect the mud present in the water.Now let’s discuss the working of Babcock and Wilcox boiler step by step.The Babcock and Wilcox boiler are generally used to produce high pressure steam in power generation industries.

Babcock and wilcox boiler working animation. If you like this article, don’t forget to share it on social networks. The main parts of this boiler are as follow.This drum is situated upside of the boiler. The demand for large size boiler units and Increased pressure led to the introduction of water tube boilers and one of the best design of a water tube boiler is the The Babcock and Wilcox Boiler was discovered by George Herman Babcock and Stephen Wilcox in the year 1967.This Babcock and Wilcox Boiler is a water tube boiler which is a multi-tubular,high pressure and externally fired water tube boiler used to generate a large amount of steam.It consists of one or more steel plates bent into a cylindrical form and riveted or welded together.
The water present in the inclined water tubes gets heated up by the hot flue gases produced by the burning of coal on fire grate. It is a horizontal axis and it contains water and steam as you can see in the diagram.It is provided for inspecting and cleaning the boiler.The Fire door is basically for providing the fire to start burning of fuel.It is basically known as the door for placing the fuel coal.After the burning of fuel coal, the completely burned fuel which becomes ash now will come to the ash pitThe main function of the baffle plate is to divert the flue gases direction so that from one side to another side hot flue gases can easily go.Upper take header connected to the drum from a very short pipe and down take header is connected to a long pipe.The water comes from the drum through a long pipe to the down take header and it flows through the entire tube.The steam formed will go up by a shorter tube (Upper take header).The Water level indicator is a measuring instrument.
Our main focus is to give our readers quality notes directly from the Professors, and Well Experienced Mechanical Engineers who already completed their education. The steam generation rate is higher about 20 ton per hour at pressure 10 to 20 bars. The entire boiler except for the furnace, are hung by means of metallic slings or straps or wrought iron girders supported on pillars. Babcock & Wilcox (B&W) began in 1867 with one patent, two friends and an unwavering commitment to reliable and effective innovation. Now let’s discuss the working of Babcock and Wilcox boiler step by step.
