What is a boiler PDF?

A steam boiler is a closed vessel, generally made of steel, in which water is heated by some source of heat produced by combustion of fuel and ultimately to generate steam. The steam produced may be supplied at low pressure for industrial process work in cotton mills, sugar industries etc.

What is boiler and 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. Water tube boiler is reverse of the fire tube boiler.

What is boiler explain?

A boiler is an enclosed vessel in which a fluid such as water is heated to produce steam or the vaporized form of a liquid. The steam or hot water is then circulated through a piping system, to transfer heat for various applications such as heating, power generation and other processes.

What is boiler and its application?

Boiler is defined as a closed vessel in which steam is produced from water by the combustion of fuel. They are also called Steam Generators. Generally steam is produced in boilers by the interaction of hot flue gases coming out from the fuel mainly coal or coke and water flowing through pipes.

What are the classification of boilers?

The boilers may be classified as follows: Fire-tube boiler and Water-tube boiler. Natural circulation and Forced Circulation. High Pressure and Low-Pressure boilers. Stationary and Portable boilers.

What are the 2 classification of boiler?

Two primary types of boilers include Fire- tube and Water- tube boilers. In a Fire-tube boiler, hot gases of combustion flow through a series of tubes surrounded by water.

What are 3 types of boiler and define each?

Different Types of Boilers

• Steam Boiler. Both hot water and steam boilers use a heat exchanger as a tool to heat water and distribute it to a piped system connected to radiators around the home.
• Hot Water Boiler.
• Natural Gas Boiler.
• Electric Boiler.
• Oil Boiler.
• Condensing Boiler.

What are main parts of boiler?

In this article we’ll take a closer look at the main components that make up a commercial boiler.

• Burner. The burner is the part of the boiler where air mixes with the fuel source and combusts.
• Combustion Chamber.
• Heat Exchanger.
• Controls.
• Supply Lines and Return Lines.
• Circulator Pump.
• Exhaust Stack.
• Conclusion.

Which type of water is used in boiler?

The boiler receives the feed water, which consists of varying proportion of recovered condensed water (return water) and fresh water, which has been purified in varying degrees (make up water). The make-up water is usually natural water either in its raw state, or treated by some process before use.
