Can anyone tell me the effect of negative pressure on temperature?
Thread Content
The temperature in one section of our furnace is constantly unstable; everything else is normal, but the negative pressure fluctuates greatly. Could anyone tell me how negative pressure affects temperature? Thank you!! I’d be extremely grateful!!
Just read the post about negative pressure; hehe, I get it now!!
The higher the negative pressure, the more heat is carried away to the convection zone. The temperature in a certain section of the furnace will drop under the same combustion conditions. The opposite is true when the negative pressure is lower
In short, the level of negative pressure is related to the shift in boiler temperature; the higher the negative pressure, the further backward the high-temperature points in the furnace move.
Large fluctuations in negative pressure: 1. Unstable combustion rate 2. Unstable speed of the exhaust fan. Effects: 1. Incomplete combustion 2. Increased heat loss
