What are boilers ?

What is a boiler ? What is the use of a boiler ? where the boilers are used ? 

At the end of this study you will get the knowledge about the boilers, its use and its working , etc.

Let’s begin with the introduction of boiler so a boiler is a very essential engineering material which is used in the production of steam in the various power plants for the production of electricity by rotating the turbine blades of the power houses 

Water is very essential in this process because for the production of steam water is heated inside the boiler and converted into the steam the water which is used in the boiler for the production of steam is known as boiler feed water

Because water is a essential unit inside the boiler there is certain requirement are required for the water to reach the requirement of the boiler like the water which is to be used in the boiler should be free from the dissolve salts(calcium and magnesium salts) also it should not contain gases such as oxygen and carbon di-oxide 

The composition which is required for the boiler feed water are as follows :- 

1. The hardness of the water should be below 0.2ppm

2. It's caustic alkalinity should be 0.15 - 0.45 ppm 

3. It soda alkalinity should be lie between 0.45 - 1.0 ppm

4. Excess soda ash should be between 0.3 - 0.55 ppm 

Hear ppm stands for parts per million which is a measuring unit of the solution. 

Also the composition of the boiler feed water varies as per the pressure requirement of the steam. 

The constituent limit of the boiler feed water is checked regularly because the unawareness of the constituent of the boiler feed water may lead to the problems inside the boiler such as priming, foaming, carry over, boiler corrosion, scale and sludge formation, caustic embrittlement these problems inside the boiler may lead to the serious explosion also. 

Uses of boilers :- 

Today boiler plays an important role in almost every unti by producing power

 

The power generated by the boilers are used by many industries to running machinery and many industrial equipment runs by using this power source 

boilers fulfills all the basic requirements of the industrial machinery by producing electricity for them 

Also the power produced by the boilers are used for the domestic purposes like as electricity supply to the houses 

On the other hand it is also used in the cold areas to supply warm water through pipelines

Besides this it has many other uses of boiler.

I hope the above mention help you to learn about boilers 

Thankyou
