Fan renovation
Thread Content
Our company currently has gas boilers, and the management plans to connect the inlet of the exhaust fan to the inlet of the blower, thereby shutting down the exhaust fan. I’m not sure if this is feasible; please experts analyze and explain this to me
It would be best to include a flowchart of the process for easier discussion. It seems that both blowers and exhaust fans are commonly referred to as “fans”. It’s just that the location where it acts differs; whether it is feasible depends on the overall process settings. For reference.
The wind that just blew in was drawn out again by the exhaust fan; it’s like a game
Feasible. With an exhaust fan, the furnace is at slightly negative pressure; without it, it is at slightly positive pressure. Excess pressure is discharged through the exhaust chimney.
It is a cyclic process: blower → air distribution → furnace → exhaust gases → blower
Gas boilers produce little dust in their exhaust gases; if the exhaust temperature is not high, recycling it can also help save energy
Oh, I misunderstood the question. Blower---Air preheater--Air distribution----Furnace----Air preheater----Flue gas------Exhaust fan-----Chimney; this is the normal operation flow for a furnace. In hydrogen production conversion furnaces, steam is used to heat the air in the air supply section before it is introduced
You know what, buy a pipe for your boss, put it in his mouth, and have him blow into the boiler – that way there’s no need for fans or air induction; maybe even the chimney can be removed!
Apart from hot air, the blower is mainly used to supply oxygen so that natural gas can burn fully. When you send back the burned gas, is it to aid combustion or to extinguish the fire? And it is easier to produce CO.
Without an exhaust fan, the system is at a slight positive pressure, and smoke is coming from all over the boiler room! Does the smoke also go out through the chimney? The stove operator might have died from the fumes! Or do you continue to raise the chimney? Is this possible?
Burn natural gas – where would the smoke come from? Don’t you read the questions carefully?
