I have a question regarding exhaust fans and blowers
Thread Content
What damage can low pressure at the outlet of the furnace blower and high pressure at the inlet of the exhaust fan cause to the equipment?
The outlet and inlet pressures of the heater blower and the exhaust fan are both determined by the furnace pressure and oxygen level. I’m curious as to how your company manages to end up with an excessively low outlet pressure for the blower and an excessively high inlet pressure for the exhaust fan； Currently, drums and induced draft fans are generally equipped with variable frequency control; if the selection is appropriate, it has little impact on the equipment itself. It’s just unclear how your heating furnaces are operated
Our system features interlocks related to the preheating and recovery process of the heating furnace; these interlocks cause the blower to stop operating when the pressure at its outlet is too low, and the exhaust fan to stop operating when the pressure at its inlet is too high. This kind of setup has not been seen before. I would like to know whether this arrangement is intended to protect the equipment, and if so, what damage it might cause to the equipment
