Fire Tube Boiler - Construction, Types and Its Working

Boiler pressure - higher pressures mean higher temperatures. The only factor affecting shell-metal temperature is the bulk water temperature of the boiler. This is a function of the return water temperature and flowrate, and also burner firing rate. Obviously, low bulk water temperatures mean low shell-metal temperatures and vice versa.

What is the range of operating pressure in a fire tube boiler?

Feb 12, 2018 · Fire tube boilers. In a fire tube or shell boiler, the hot combustion gases produced by the burner are passed through small tubes arranged in a pressurised cylindrical drum and surrounded by water. Heat energy is transferred to the water which is heated up until it becomes steam.

A comparison between water tube and fire tube boilers

High pressure boilers use water-tubes since fire-tubes are not sufficient in regards to pressure or temperature, even if the boiler were larger and burned more fuel. In order for fire-tube boilers to create the same amount of pressure, the system would require thicker walls and bigger tubes but still would not be able to reach high enough
