Smoke Tube Boilers In this boiler products of combustion [flue gases] , the combustion that takes place inside the furnace located at the bottom of boiler passes through the smoke tubes. All the smoke tubes are completely submerged in fresh water to a level inside the steam drum.
The smoke tube boiler is used with low operating pressures up to around 40 bars and a power range between 5 and 25 MW. Depending on the fuel, the combustion chamber can be used either cooled or uncooled.

Smoke tube boiler and water tube boiler are the main types of industrial boiler in global market. They are differ from not only structure, but also usage. Smoke tube boiler. Smoke tube boiler, as its name suggests, of which smoke or heat flowing through boiler tubes and the water surrounds outside of the tubes to be heated and turned into steam.
Smoke Tube Boiler ( Internal Furnace Smoke Tube Boiler) internal design, most of the radiative combustion heat is transferred to the surrounding water and only small amount of heat is lost to the environment which can also be taken care using various techniques.Our Internal Furnace Smoke Tube Boilers - Intech Model
Enter the boiler flue box and cut a hole in the side of the relevant smoke tube. Clean the rim of the smoke tube with a wire brush. Cut a circular plate (15 mm thick) of the same diameter as the smoke tube and chamfer the top edge to 30 degrees by grinding. Fit the plate into the top of the smoke tube and weld it in position as shown.
Fire-tube boiler - Wikipedia. 2019-3-30 · The earliest form of fire-tube boiler was Richard Trevithick's "high-pressure" Cornish boiler. This is a long horizontal cylinder with a single large flue containing the fire.
The functionality of such boilers is totally opposite to that of smoke tube boilers. In water tube boilers, water flows inside the tubes and heat surrounds these tubes. The pressure generated in water tube boilers is higher than the pressure generated in smoke tube boilers. Both the boilers are shell and tube type. Fire or smoke tube boilers ...
