Apr 17, 2015· Type of fire tube boiler Lancashire Boiler It is stationary fire tube, internally fired, horizontal, natural circulation boiler. This is a widely used boiler because of its good steaming quality and its ability to burn coal of inferior quality. This boiler is set in brickwork forming external flue so that the external part of the shell forms
Parallel tube boilers place all of their fire-tubes in a single parallel group, running from side to side of the boiler shell. The best known of these is the Cochran design.. Cochran boiler. The Cochran boiler was produced by Cochran & Co. of Annan, Scotland. It is widely used in marine practice, either fired directly by coal or oil fuels, or else used for heat recovery from the exhaust of
Nov 24, 2016· Fire Tube boiler is the simplest form of the internal furnace, vertical fire tube boiler.Fire tube boilers are a portable boiler and it requires a small floor space. The steam rating in fire tube boilers doesn’t exceed 2500 kg per hour and pressure is limited to 10 bars.
Cochran Boiler Definition: Cochran boiler is a fire tube boiler (Fire inside the boiler and water surrounding to them) in which coal or gases as a working fluid is used, for generating the steam and that steam further used for several purposes. Now comes to the construction, Cochran Boiler Parts or Construction:
Firebox—the area of a boiler where the burners are located and where radiant heat transfer occurs, p. 296. Fire tube boiler—a device that passes hot combustion gases through the tubes to heat water on the shell side, p. 298. Igniter—a device (similar to a spark plug) that automatically ignites the flammable
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 four major historical types of boilers: low
