Coil Type Oil Fired Boiler

Coil-type boilers / Diesel Fired boilers are water tube designs, the water travels through the coil and is surrounded by flue gases. The generated steam is directly fed to the process.The coiled tube boiler is a type of Water Tube Boiler in which a cylindrical furnace envelope is formed by multistart, helically-coiled tubes in which water is boiled. Firing is by oil or gas and the burner is provided usually in the base, although sometimes in the roof of the furnace.In coil type boiler the water flows inside the coil and the flame is on outside it, providing heat to produce steam. WORKING: The boiler comprises a jacketed MS shell housing a helical coil, arranged vertically inside the boiler. Water enters from the bottom of the coil and travels upwards.
