Steam boilers

A steam boiler is a closed vessel that uses heat from a fuel source to convert water into steam, which is used in various industrial and commercial applications such as heating and power generation. The basic working principle involves the combustion of fuel inside the boiler’s combustion chamber, which produces high-temperature gases that transfer heat energy to the water surrounding the chamber, causing it to boil. Steam boilers come in different types, such as fire-tube and water-tube boilers, and have essential roles in providing heat and steam for various applications. Proper maintenance and adherence to safety protocols are crucial for their efficient and safe operation.

Purpose of Steam Boiler

• For generating power in steam engines or steam turbines

• In process industries for various processes.

• For heating the buildings in cold weather and for producing hot water for hot water supply.

Here we are discussing High pressure Steam Boilers, Their components and auxiliaries based on practical experience gained by in thermal power plant. That is little different than taught in theory / books. My intension is to know how about the Thermal Power plant basics as per site and location wise. This is definitely helpful to Engineering students, Trainee Engineers and those who are facing Competitive exams. Its my sincere effort and wish to share my knowledge to you people as I am getting good response for my other courses on this platform. Hope to keep the same relation and continue to upload much more about Thermal Power Plant in near future also. Best of luck and have a nice day.
