2021/1/24 · Firetubes:- Through this channel or pipe, the hot flue gas passes to the smokebox. As this is a fire-tube boiler, the regular flow of hot gases can damage these tubes. Generally, these tubes are made up of seamless steel e.g. carbon steel and alloy steel. The materials of these tubes are different for low pressure, medium pressure, and high

Chimney: It is a vertical pipe located at the back end of the chimney. Flue gases are released into the atmosphere via the chimney. Cornish Boiler Working Principle: A Cornish boiler works on the principle of Thermal conduction, that is hot gases emerging from the combustion of fuel with air pass through a fire tube and transfer the heat to the surrounding water by thermal conduction.
