Which boiler is used for large power plant?
There are many advantages of water tube boiler due to which these types of boiler are essentially used in large thermal power plant. Larger heating surface can be achieved by using more numbers of water tubes.
Which boilers are not suitable for large power plants?
Clarification: The operating pressure for fire tube boilers is limited to 16 bars. For a given power it occupies more floor area, hence it is not suitable for large power plants.
What are the three types of boilers?
There are three main types of boilers you can install into your home: combi boilers, heat only (regular boilers) and system boilers.

What is economizer in boiler?
Economizers are heat exchangers that transfer the heat in the flue gas to another medium‚ generally the boiler feed-water‚ although other streams are sometimes used such as make-up water. There are 2 types of economizers: non-condensing and condensing.
Which type of water is suitable for 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.
What is the purpose of boiler in power plant?
Boilers are used in power plants in order to produce high pressured steam, so that the plant can generate electricity. The process that does this is known as the Rankine cycle. The boiler takes in energy from some form of fuel such as coal, natural gas, or nuclear fuel to heat water into steam.
