Horizontal fire-tube boiler comprises a cylindrical housing 1, which is adjacent the front tube plate 2 and back plate 3. The space bounded by the casing 1, a pipe Board 2 and the bottom 3 filled with water to a certain level.
Dec 21, 2018 · 2018-12-7 · A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes.
The horizontal fire-tube boiler is also typical of marine applications, using the Scotch boiler. Vertical boilers have also been built of the multiple fire-tube type, although these are comparatively rare: most vertical boilers were either flued, or with cross water-tubes.
Dec 02, 2016 · 1. Horizontal Return Tubular Fire Tube Boiler. As one of the oldest and most simple designs for industrial boilers, the Horizontal Return Tubular fire tube boilers are still being produced today.
