What is daught, what kind of draught used in boiler chimney
Answer Posted / pratik patel
The definations given by Mangesh and Santosh are right.
->the problem with the Forced daught boilers is that the
pressure in the Furnace is higher than the outside so when
there is leakage or if you open a inspection window the
flame will burst out.
->the problem with the Induce daught is that the pressure
is negative in the furnace. so there is a chance that
outside air can contaminate the furnace and combustion
through leakage or openings of inspection window.
--> so normaly balanced daught is used in which where both
fans (force daugth & induce daught fan) are provide one
before furnace and one after furnace.
these fans keeps the furnace pressure in balanced condition,
generally the pressure inside the furnace is kept negative
5-10 mm water column.
