Heating furnace
Thread Content
Dear experts in the marine field, I would like to ask about the relationship and principle between furnace negative pressure and the wall temperature of the furnace
I really can’t answer that question. Let me explain it through practical operations: the furnace chamber must be under negative pressure, and the way to achieve this is by adjusting the exhaust fan (in our case, it’s a variable-frequency fan) as well as the flue dampers. For adjusting the flame, there are 3 dampers and 1 air valve; in a stable state, these dampers have a significant impact on the oxygen level and negative pressure in the furnace chamber. However, I really can’t establish a connection between the furnace temperature and negative pressure

The negative pressure in the furnace is related to the dampers and flue baffles.
