Construction of Fire Tube Boilers

Construction of Fire Tube Boilers Points : Construction of Fire Tube Boilers This Boiler has of a vertical cylindrical case had a curved top. The Case is prepared of mild steel plates. Furnace is too falcate in shape with it is hydraulically pushed as of one plate with no a single weld. Therefore, furnace is strongest construction below compression. Fire aggravate is given in furnace with the ash-pit is provide under the grate. In firebox fire door with a damper are give. Bordering to fire box the boiler have a burning chamber which is dry parched with lined by fire bricks, secure to burning chamber a number of horizontal smoke tubes are give. This tube of equivalent length with arranged in a group by extensive space in among them with the shell so as to assist convection current. End of these burn tubes are fixed in smoke box tube plate with burning chamber tube plates. Tubes are purely pressed in holes of tube plates with then extended at ends to create steam light joints. Smoke box is build of steel plates with is fixed by hinged door which gives a simple way in to smoke tubes for clean-up and inspect. Stack is providing at top of smoke box for release of gases to atmosphere. Furnace is enclosed through water on every side but at opening for fire door with combustion chamber.
