Classification of boiler tubes
1. Fire boiler tube
A fire tube boiler is a type of boiler in which hot gas passes from a fire through a sealed container of water through one or more pipes. The heat from the gas is transferred through the tube wall through heat conduction, heating the water and eventually producing steam. Firetube boilers are the third of four historical boilers: low-pressure tank or "haystack" boilers, flue boilers with one or two large flues, fire tube boilers, and flue boilers with a permit. High-pressure multitube boilers .
2. Open the water pipe
A water main is a type of boiler in which water circulates in heated tubes around the outside of a fire. The fuel is burned in the furnace to produce hot gas, which heats the water in the steam generating tube. In smaller boilers, additional power generation tubes separate into the furnace, while larger utility boilers rely on water injection tubes that form the walls of the furnace to produce steam. High pressure water boiler tube: Then the hot water rises to the steam drum. Here, full and steam is drawn from the top of the drum.
