What is the use of boiler drum?

The boiler drum which is also known as steam drum is used on water tube boiler. The primary purpose is to separate the saturated steam from the steam-water mixture that leaves the heat transfer surface and enters the drum.

What are drum boilers?

Overview. In a drum boiler, the circulation of water is produced through the density difference of water in the down comer pipe and the water/steam mixture in the furnace tubes.

Which type of boiler is used in thermal power plant?

There are two types of boilers are used in sub critical, super critical and ultra-super critical coal fired thermal power plant: Pulverized coal-fired Boiler. Fluidized Bed combustion (FBC) boiler.

What is boiler drum pressure?

In a drum-type boiler, most of the working medium (water and steam) is at saturation pressure and temperature. As load increases, so does drum pressure (PD), increasing the saturation temperature and steam enthalpy in the process.

What is the working principle of boiler?

Working Principle of a Boiler Hot gases are formed by burning fuel in the furnace. These gases are made to come in contact with the water vessel, the point where the heat transfer takes place between the steam and water. Thus, the boiler’s basic principle is to convert water into steam with heat energy.

What is boiler types of boiler?

There are mainly two types of boiler – water tube boiler and fire tube boiler. In fire tube boiler, there are numbers of tubes through which hot gases are passed and water surrounds these tubes. In water tube boiler the water is heated inside tubes and hot gasses surround these tubes. …

How does a boiler work?

Hot jets that are linked to a heat exchanger within the boiler transfer heat to the water that flows over the exchanger. An electric pump then pushes the hot water through to your radiators and taps. All new boilers are condensing. This heat is then used to heat water that returns from your central heating system.

What is boiler pressure parts?

A boiler is classified as a fired pressure vessel. Parts of the boiler that are subjected to high internal pressure of steam or water are referred to here aspressure parts. Tubes, drum, and headers are examples of pressure parts. Other components likes burners, etc., are not subjected to such internal pressure.

What are the 2 types of boilers?

There are three main types of boiler: combi, heat only and system. Heat only boilers (aka conventional or regular) work with a cylinder in the airing cupboard. System boilers are often found in modern homes with an ‘unvented’ hot water cylinder. Combi boilers produce instant hot water.

What are the main parts of a boiler?

The key elements of a boiler include the burner, combustion chamber, heat exchanger, exhaust stack, and controls. Boiler accessories including the flue gas economizer are also commonly used as an effective method to recover heat from a boiler.

What is the principle of boiler?

How does a steam boiler drum work?

BOILER DRUM ROLES – Electricity , Power generation … The steam-free water is recirculated within the boiler with the incoming feedwater for further steam generation. The saturated steam is removed from the drum through a series of outlet nozzles, where the steam is used as is or flows to a superheater for further heating.

How does a thermal power plant work?

How does Thermal Power Plant work? In thermal power plants, the heat energy obtained from combustion of solid fuel (mostly coal) is used to convert water into steam, this steam is at high pressure and temperature. This steam is used to rotate the turbine blade turbine shaft is connected to the generator.

Which type of boiler is used in thermal power plant of low cost?

Normally horizontal return fire tube boiler is used in thermal power plant of low … Three Drum Bent Tube Boiler. A thermal power station is a power station in which heat energy is converted to electric power. In most of the places in the world the turbine is steam-driven.

What is a water tube boiler used for?

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.
