Boiler, various applications, and parts

In the previous articles, we talked about the boiler. In this article, we are going to talk about boiler parts. We will first have an overview of the boiler and its applications. Stay with us. 

What is a boiler?

A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central heating, boiler-based power generation, cooking, and sanitation.

Different types of boilers have many applications in domestic and industrial applications.

Many manufacturing facilities can recapture energy by installing more efficient steam equipment and processes and applying energy management practices. 

Different parts of the Boiler

 
The parts of the boiler are:
 
  • Circulator pump
  • Aquastats
  • Combustion chamber or firebox
  • Burner

Burner:
 
One of the most important parts of boiler is the burner which is where the mixing of the air with the fuel source happens, resulting in the combustion which provides the necessary heat to heat up the fluid. They are responsible for initiating the combustion reaction in the system with the electronic signal of the thermostats to the burner. This signal informs the system when there’s a need to produce heat. The burner uses the fuel pumped from an outside source with a filter mechanism. There’s a nozzle designed on the burner to turn this fuel into the spray and ignites it initiate the combustion inside the firebox.

The pressure vessel of a boiler is usually made of steel (or alloy steel), or historically of wrought iron. Stainless steel, especially of the austenitic types, is not used in wetted parts of boilers due to corrosion and stress corrosion cracking.However, ferritic stainless steel is often used in superheater sections that will not be exposed to boiling water, and electrically-heated stainless steel shell boilers are allowed under the European "Pressure Equipment Directive" for the production of steam for sterilizers and disinfectors. Read more
 
In the following, we will introduce the different parts of the boiler.
