Chamber temperature and negative pressure of the heating furnace
Thread Content
Is there a specific quantitative relationship between the furnace temperature of the heating furnace and the negative pressure? For example, if the furnace temperature is 200 degrees, what negative pressure value would be appropriate? What about 300 degrees, and so on?
Negative pressure has little to do with furnace temperature; check the technical specifications of your furnace. The furnace temperature is determined by the amount of heat required for your reaction/heating process, and the negative pressure in such furnaces is usually between -25 and -50.
There is no relationship between the two; furnace temperature is related to the amount of fuel. It’s sufficient to keep the negative pressure within a certain range.
The furnace is a place for heat exchange; the temperature in the furnace chamber is provided by the fuel, and furnace pressure control is aimed at ensuring more complete combustion of the fuel.
