Fire-tube boiler - Wikipedia

2019-5-13 · A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam. The fire-tube boiler developed as the third of the

Steam and high temperature hot water boilers 6 Technology overview Boilers A boiler is a device that converts the chemical energy of a fuel into a useful heat output, such as steam or hot water. The fuel type most commonly used in the UK is gas, but some older coal …

Boiler - Wikipedia

2019-5-23 · Fire-tube boiler: Here, water partially fills a boiler barrel with a small volume left above to accommodate the steam (steam space).This is the type of boiler used in nearly all steam locomotives.The heat source is inside a furnace or firebox that has to be kept permanently surrounded by the water in order to maintain the temperature of the heating surface below the boiling point.

Boiler - an overview | ScienceDirect Topics

Burning of clean gas produces a temperature of 850 °C, which vaporizes the water circulating in the boiler. The steam temperature is 540 °C and pressure 121 bar. The torch burner is a safety device in case the boiler encounters a problem, and it is not possible to feed all of the gas coming from the gasifier line into the boiler.
