A non IBR water tube boiler would roughly generate a flue gas of temperatures 150–170. These gases have to pass through the shell in 2 passes to preheat the incoming combustion air and thereafter the economiser. For starters a squared shell open a
In a fire tube or shell boiler, the hot combustion gases produced by the burner are passed through small tubes arranged in a pressurised cylindrical drum and surrounded by water. Heat energy is transferred to the water which is heated up until it becomes steam.
Horizontal Return Tubular boiler (HRT) has a horizontal cylindrical shell, containing several horizontal flue tubes, with the fire located directly below the boiler's shell, usually within a brickwork setting. Variations. Water tubes. Fire-tube boilers sometimes have water-tubes as well, to increase the heating surface.

Schematic diagram of a "locomotive" type fire-tube boiler. In the locomotive-type boiler, fuel is burnt in a firebox to produce hot combustion gases. The firebox is surrounded by a cooling jacket of water connected to the long, cylindrical boiler shell.
Aug 22, 2018 · A water tube boiler is such kind of boiler where the water is heated inside tubes and the hot gasses surround them. This is the basic definition of water tube boiler. Actually this boiler is just opposite of fire tube boiler where hot gasses are passed through tubes which are
Oct 19, 2018 · The simple vertical boiler is a fire tube boiler and easy to understand the working principle of fire tube boilers. Simple vertical fire tube boiler produces steam with low pressure and in small quantities. It uses for low power generation or for limited space. It consists of a cylindrical shell surrounding a nearly cylindrical firebox/ furnace.
