View MoreFuel is bunt in a furnace and hot gasses are produced. These hot gasses come in contact with water vessel where the heat of these hot gasses transfer to the water and consequently steam is produced in the boiler. Boiler are used in power plants in order to produce high pressured steam, so that the plant can generate electricity.
View MoreCoal thermal power plant is the most common power plant used in worldwide and coal fired CFB power plant boiler plays an important role in it. In coal thermal power plant, the steam is produced in high pressure in the CFB steam boiler due to burning of coal fuel in boiler furnaces. This steam is further supper heated in a super heater.

Examples of vertical boilers are: simple vertical boiler and Cochran boiler. (ii). Horizontal Boilers: When the axis of the shell in a boiler is found horizontal than it is called a horizontal boiler.
View MoreINTRODUCTION OF THERMAL POWER PLANT. Thermal power plant or steam power plant is a generating station which converts heat energy of fossile fuels into electrical energy.Generally bituminous,brown or peat type coal are used as the fuel of coal basesd thermal power plant. In a thermal power palnt, coal is burnt in a big boiler which produces steam at high pressure and temperature. This steam is passed through a steam …
View MoreMay 25, 2018· A boiler in thermal power plant utilizes the heat for converting water into steam. Steam boilers are often classified into two types. Water tube boilers. Fire tube boilers. In water tube boilers the water flows through tubes and hot combustion gases flow over these tubes. Whereas in fire tube boilers the tubes are surrounded by water and hot combustion gases flow through these tubes.
View MoreCoal-fired thermal power plants systems use several types of process fans. Based on the size of the boiler or steamer the rating of the fan used differs and based on the type of air flow and the process involved different types of draught fans are used in thermal power plants. An attempt is being made to explain the types of draught fans used
View MoreIt is estimated that almost 20% of manufacturing cost of a thermal power plant belongs to the boiler. As an example, manufacturing of an oil-fired 300 MW boiler needs up to 200 USDkW investment .The annual cost of boiler tube failures is more than 5 billion USD, therefore monitoring and root cause failure analysis of boiler components is an
View MoreOct 03, 2020· A boiler is a pressure vessel which is used to generate high-pressure steam at a saturated temperature. At this high pressure and temperature generally, bi-drum water tube boilers are used. Thermodyne Engineering Systems manufactures water tube boilers of various sizes and capacities that can run on various fuels.
View MoreThese types are most commonly used for biomass and coal. Pulverized fuel boiler: Coal is pulverized into a fine dust (about 0.1 mm in size), and is fed into the boiler in a stream of air. They are by far the most common boiler types for coal. These boilers can reach efficiencies of over 90% when they are well run.
