A problem with starting the induced draft fan
Thread Content
Does temperature have an impact on it when starting the induced draft fan?
When the temperature of the smoke increases, the amount of smoke also increases, and the flow velocity rises as well.
So, is there a requirement regarding temperature when it’s first started up? The experts at my company say it cannot be turned on at low temperatures; I don’t understand this
So what is the function of the exhaust fan in your area? If it is used to create negative pressure, then this problem shouldn’t occur; moreover, the exhaust fan should start working first before ignition takes place.
The exhaust fan cannot start at low temperatures; let’s analyze this: 1. Is it possible that the lubrication system of the exhaust fan fails to function properly at low temperatures?； 2. If the flue gas cannot be cooled to a low temperature, then how can the flue gas be heated? It’s not possible to first raise the temperature of the furnace chamber and then create a negative pressure; this is even more difficult to achieve and prone to problems. 3. Please provide a detailed explanation, OP, so that we can discuss it together.
It means that the flue gas temperature cannot be too high; if it’s not possible to start the induced draft fan first, then the air blower must be turned on first, with the chimney opened for venting in order to raise the temperature
When starting the induced draft fan, the air damper should be gradually opened from the closed position to its normal opening degree
It means that the temperature of the flue gas cannot be too high. If it’s not possible to start the induced draft fan first, then one has to start the air blower instead, and open the chimney for venting in order to raise the temperature. Has anyone ever heard of such a thing? It’s unheard of
I ask everyone for advice because I don’t understand it either; I’m not aware of it either.
Starting at low temperature and returning to superwork can potentially damage the motor
Starting at low temperatures is harmful to the motor, as the volume of gas increases as the temperature rises, resulting in lower smoke density and thus less load on the fan. If the temperature is low, the density is high, and consequently the load on the fan is greater.
