What is Boiler? Boiler Components & Application of Boiler in detail

Fire tube boiler

Boiler Definition

Boiler is defined as  

Boiler is a closed cylindrical shape vessel in which water is heated to converts into the vapour to generate steam buy the combustion of fuel
In the presence of atmospheric oxygen.
And generate steam futher used for various applications like for
electricity or nuclear energy.

The boiler system is a device which have functions to the generate and transmit steam,
And also control it.

Boiler is the main  component of any thermal power plants

Water tube boiler

Classifications of Boiler:

There are following Boilers Types:

1. According to the position of water and hot tubes

Components of a Boiler Systems

Boiler design is made up of 3 main components–

Feed water system

Steam system

Fuel system

1. Boiler Feed water System

A system through which water is send to boiler tank
Where this water is converts into steam by using boiler.

All this system is called water feed system.

called Feedwater & system that regulates feed water.

Mainly two types of feed water systems are used in boilers:

Open feed System
Water is not come back means water is again and again arranged from outside the boiler plant.

Closed feed system
Condensed steam returned from the processes

There are two main sources to feed water inside the boiler:

Raw water arranged from outside the boilers plant processes ( Called: Makeup Water)

2. Boiler Steam System

Boiler steam system means how a boiler generate steam futher how it collect and controlled.
And
Steam systems send steam generated in the boiler process.

Throughout the process, steam pressure is controlled and regulated with the help of boiler's parts such as valves, steam pressure gauges, etc.

3. Boilers Fuel System

Fueling is the main parts of boilers process & fuel system consists of all the components and equipment to send fuel to generate the required heat for generating steam.

The equipment required in the fuel system depends on the type of fuel.

Boiler Applications

 

The Boilers have various application in different industries such as in:-

Power Sector

Textiles

Plywood

Food Processing Industry

FMCG

Sugar Plants

Thermal Power Plants
