What is Boiler | Components & Application of Boiler System

What is Boiler?

A boiler is defined as “A closed vessel in which water or other liquid is heated, steam or vapor is generated, steam is superheated, or any combination thereof, under pressure or vacuum, for use external to itself, by the direct application of energy from the combustion of fuels, from electricity or nuclear energy.

Boiler is a main working component of thermal power plants

Fuel Used in Boiler

Boiler Furnaces compatible with

Solid Boiler fuels:

Liquid Boiler Fuels:

  • LDO
  • Furnace oil

Gaseous Boiler Fuels:

  • LPG
  • LNG
  • PNG can be used to carry out the combustion for the specific purpose.

Components of Boiler System

There are 3 backbone components of any boiler system:

1. Boiler Feed Water System

Water that converts into steam by steam boiler system called Feed water & system that regulates feed water called Feed water system.

There are two types of feed water systems in boilers:

  • Open feed System
  • Closed feed system

There are two main sources of feed water:

  •  Condensed steam returned from the processes
  • Raw water arranged from outside the boiler plant processes ( Called: Makeup Water)

2. Boiler Steam System

Steam System is kind of main controlling system of boiler process. Steam Systems are responsible to collect & control all generated steam in the process.

Steam systems send steam generated in the process to the point of use through pipes ( piping system). Throughout the process, steam pressure is controlled and regulated with the help of boiler system parts such as valves, steam pressure gauges etc.

3. Boiler Fuel System

Fueling is the heart of boiler process & fuel system consists of all the necessary components and equipment to feed fuel to generate required heat. The equipment required in the fuel system depends on the type of fuel used in the system.
