Schematic diagram of a marine-type watertube boiler. 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 boils water in the steam-generating tubes.
This boiler has a horizontal shell at the top and the water tubes are inclined at a particular angle. The feed water is fed to these inclined tubes. As the fuel is burnt in the burning area, heat is generated along with the flue gases. The flue gases will spread all over
Hot water or steam boilers are relatively similar in design (Figure). The boiler pressure vessel is a horizontal, cylindrical tube closed at both sides with an end plate and insulated all around. There is a flame tube (1st pass) in this pressure vessel, which is fired
There are Several Types of Fire tube Boilers, they are Cornish Boiler : This boiler has a long horizontal cylinder with a single large flue consisting the fire Figure 1: Cornish Boiler. Page 2 of 34. Lancashire boiler : Same as Cornish boiler, this has two large flues compressing the fires.
Fire-tube boiler: Fire-tube boiler is those boiler in which the fire or hot gas is present inside the tubes and water surrounds these fire tubes. Since fire is inside the tubes and hence it is named as fire tube boiler. The heat from the hot gases is conducted through

Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper
17/4/2015 · 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 part of the heating surface.
Economizer (heat exchanger) is the boiler accessory used to recover the heat of flue gas that leaving the boiler by heating feed water. The efficiency of a boiler can be increased with an economizer. 60C rise in feed water temperature with the help of economizer can save up to 1% of fuel.
