How to Handle Both Forced Draft Fans Trip in

2020-12-23 · Boilers have forced draft (FD) fans to supply air for combustion of fuel. Any trip of major equipment in boiler causes the boiler parameters to vary widely before it stabilizes depending upon the action taken by the operator. The important factors to be understood in a trip of equipment in a boiler are mainly four, the specific cause of trip, plant response to the trip, immediate operator

What is Boiler Draught? Types, Classification,

2. Forced Steam Jet Draught. Steam from the boiler after having been throttled to a gauge pressure of 1.5 to 2 bar is supplied to the jet or nozzle installed in the ash pit. The steam rising out of nozzles with a great velocity drags air by the fuel bed, furnace, flue passage and then to the chimney.
