Draft (boiler) - Wikipedia

2020-4-20·The combustion rate of the flue gases and the amount of heat transfer to the boiler are both dependent on the movement and motion of the flue gases. A boiler equipped with a combustion chamber which has a strong current of air (draft) through the fuel bed will increase the rate of combustion (which is the efficient utilization of fuel with

Classification of Boiler Draught: Natural and Artificial

2020-4-8·In actual practice the induced draught fan maintains a draught of 0.2 to 0.5 mm of water in the furnace so that the leakage of furnace gas into the boiler room is prevented. Thus, in a balanced draught system the forced draught fan overcomes the resistance in the air pre-heater and chain grate stoker while the induced draught fan overcomes

MARINE ENGINEERING KNOWLEDGE BY RAJAN -

If the boiler is contaminated with foreign substances like oil, chemicals, corrosion products etc., it is very important to act immediately to avoid damages to the boiler. Layers of thin oil films, mud, etc. exposed to the heating surfaces causes a bad heat transfer in the boiler, leading to overheating followed by burned out pressure parts.
