Boiler types and working

A boiler is a closed vessel in which water under pressure is converted into steam. It is one of the measure components of a thermal power plant the boiler is always designed to absorb maximum amount of heat released in the process of combustion. This heat transferred to the boiler by all the three method of heat transfer. the method is shown below. 


1. Conduction

2. Convection

3. Radiation

Boiler types in thermal power plant

There are two boiler types in thermal power plant. Which is given below .

1. Fire tube boiler

2. Water tube boiler

1. Fire tube boiler


This boiler is so named because the process of combustion passes through the tubes which surround by water depending on weather the tubes are critical and horizontal tube boilers. A fire tube boiler vertical fire tube boiler occupies little flow space.  They are economical only for low pressure and there for available in small sizes having steam capacity of about 1500 kg/hrs.

2. Water tube boiler

In this boiler water flows inside the tube and hot gases flow outside the tubes.  Water tube boilers are classified as shown below.

1. Horizontal boiler

2. Vertical boiler

3. Inclined tube boiler

Whether the tube are vertical or horizontal or inclined.  The circulation of water in the boiler may be natural or forced through the action of pumps.  The factors which affected the choice of a boiler are initial cost, availability, maintenance cost, labor cost, space and fuel cost.

Hence it is the boiler types in thermal power plant. if you will find any incorrect above please comment below.
