Boiler in thermal power plant accumulates the steam and build up a pressure to expend it in turbine and convert thermal energy to mechanical energy. The generator which is connected to turbine converts the mechanical energy into electric energy.
High-pressure water tube boilers will heat steam above 15 psi and water at pressures that exceed 160 psig. Temperatures in high-pressure boilers will exceed 250 degrees F. High-pressure boilers are used in industries and designed to generate the steam found in power plants, dry cleaners and laundromats.
'''Boiler'''- An enclosed vessel in which water is heated and circulated, either as hot water or as steam, for heating or power. A container, such as a kettle, is used for boiling liquids. In our context, a boiler is "a piece of heating equipment that is used to heat water for use in a hot water-based heating system."
The condensate (hot water) can then be returned to the feed water tank, from where it again is pumped and provided to the steam boiler. What Is Steam Generator: A steam generator is a form of low water-content boiler, similar to a flash steam boiler. The usual construction is as a spiral coil of water-tube, arranged as a single, or monotube, coil.
Steam Cycle. A steam cycle power plant is operated using the Rankine cycle. Water enters a boiler where it is heated to create steam. The steam is then sent through a steam turbine that rotates the shaft of a generator to create electricity. The steam exits the turbine into a condenser, which converts the steam back into saturated water.
Steam boiler is a cylindrical shape closed vessel which has sufficient capacity to contain water and steam.Generally, water or other fluid is stored in steam boiler to generate steam.This water or fluid is heated by flames or hot gasses which are produced by combustion of fuels and consequently steam is generated in the boiler at different pressure according to boiler's size and it's specification.This steam is now passed through a pipe and supplied into different production unit,power plant
Water tube boilers can be fabricated in every village which becomes 2/3 cost of steam power plant. Ordinary welders can be trained to make 300 % fully safe boiler for power generation at very cheap rate in any part of the world.
The water present in the boiler is heated up by means of a furnace and as the density of steam is less than the density of water, the steam will deposit on the surface of the water. The steam is taken from the boiler and is superheated so that, the steam present should be free from the water molecules.
The steam generation rate in water tube boiler is high i.e. 450 tonne s per hour. For a given power the floor area required for the generation of steam in this boiler is less i.e. 5 m 2 per tonne
Oct 28, 2013 · Water Tube Boilers – In contrast to fire tube boilers; a water tube boiler uses the water rather than the heat which is contained inside of a system of interconnected tubes. The heat moves around the tubes, thereby heating the water within the tubes and gradually transforming it into steam.

Apr 23, 2016 · Since the water is present insides the tubes hence these boilers are called water tube boiler. High pressure steam is produced by these boilers. The pressure of the steam is about 165 bar. These boiler falls under the category of high pressure boiler. The steam generation rate in water tube boiler is high i.e. 450 tonnes per hour.
The drum itself a large cylindrical vessel that functions as the storage and feeding point for water and the collection point for water and steam mixture. This is the largest and most important pressure part in the boiler and weighs in the range 250 Tons for 600 MW power plant. Water Walls
The steam is taken from the boiler and is superheated so that, the steam present should be free from the water molecules. Thus the superheated steam strikes the turbine blades with a high speed which makes the turbine to rotate.
In a typical Water tube boiler design as shown in the figure, it consists of two drums the steam drum and the water or mud drum. On this design straight tubes were rolled into mud drum, and the front headers were connected to the steam drum. The rear header was connected to a horizontal box header, which was also attached to the steam drum.

A boiler or Steam Generator (prime mover) is an integral device in a fossil fuel power plant used to produce steam by applying heat energy to water. A boiler incorporates a furnace in order to burn the fossil fuel (coal, gas, waste etc.) and generate heat which is transferred to water to make steam.
Aug 22, 2018 · A water tube boiler is such kind of boiler where the water is heated inside tubes and the hot gasses surround them. This is the basic definition of water tube boiler. Actually this boiler is just opposite of fire tube boiler where hot gasses are passed through tubes which are surrounded by water.
Apr 23, 2018 · In Water Tube Boiler water will be heated inside the Boiler Tube and heat will pass around the Tubes. Generally, heat passes from the boiler Furnace or Combustion Chamber to around the Boiler Tube.

This course is designed to familiarize participants with the basic principles associated with the flow of water and steam in various types of boilers. After completing this course, participants should be able to describe the flow path of water through a typical drum-type boiler, explain the differences between natural circulation and controlled circulation, and describe the functions and
Also called D type water tube boilers, they are the most common type of small- to medium-sized boilers. The upper drum, called a steam drum, is where saturated steam leaves the boiler. The lower drum , called the mud drum, receives the liquid feedwater and collects sediments that are carried into the boiler and settle at the bottom of the drum.
The main purpose of steam boilers is to generate steam, and so the way in which the steam is generated and consumed forms the major category. The major two groups of boiler application are Industrial steam generators and power generation boilers. Boilers are also classified as fire tube and water tube boilers.

Jan 15, 2017 · Answer Wiki. 6 Answers. , works at TATA Power. Temperature inside boiler (furnace) is around 1100 deg to 1200 deg. Although it is favorable to keep it under 1100 deg or otherwise ash in flue gas will melt as forming clinkers and it will stick to to boiler walls.
This design is normally used in smaller plants. Here, steam is used to maintain tank water temperature at around 105°C, which removes air from the water. Vacuum principle. Here, an ejector pump is used to create a vacuum in the tank. This causes the tank water to start boiling because of the low temperature, which in turn removes air from the water.
