1. Natural draught:In this, only chimney is used for producing the draught. 2. Artificial draught:In this, the draught is produced by steam jet or by fan. 1. Steam jet draught:Steam jet is used for creating draught in the system. 2. Mechanical draught:Fan or blower is used for creating draught in the system. … See more In natural draught, a tall chimney is erected. The chimney is a vertical tubular masonry structure or reinforced concrete. It is constructed for enclosing a column of exhaust gases to produce draught. The flue gases are … See more In modern power plants, the draught should be flexible to meet the fluctuating loads and it should be independent of atmospheric … See more In a induced draught, a blower is placed near (or) at the base of the chimney. The fan is driven by steam or electricity. The fan sucks the flue gas from the furnace creating a partial vacuum inside the furnace. Thus … See more In this draught system, the blower is located at the base of the boiler near the grate. The blower is driven by steam or electricity. Air is forced to the furnace by forced fan and the … See more WebJun 15, 2011 · Natural draught: The natural draught is obtained with the use of tall chimney which may be sufficient or insufficient to overcome the losses in the system. Its usefulness depends upon the capacity of the plant and duct work. This system of producing the draught is useful for small capacity boilers and it does not play much important role in …
