Which draught system is used as conjunction with chimney draught? Correct Answer Forced steam draught

The high velocity steam coming out from the nozzle drags the air column along with it creating suction. The kinetic energy of air and steam mixture is converted into pressure energy forcing air through the coal bed to the furnace. So, Forced steam draught is used as a booster in conjunction with chimney draught.
