flue gas temperature

flue gas temperature

flue gas temperature

(OP)
I burn some CFM of fuel (natural gas) in oven at some % excess air. Air comes in at some Relative humidity, temperature and pressure. Fuel comes in at some pressure and temperature.

Are their any tables that I can refer to, to decide flue gas temperature?

RE: flue gas temperature

commonly used temperatures are 110C for gas, 130C for coal and 150C for oil

RE: flue gas temperature

1500C can be bottle neck for high sulphur content fuels, for ex. 4.5%.

RE: flue gas temperature

Kagadpencil:

The question you ask disregards some vital elements.  The configuration of the oven, stack, etc. and the process.  What type of process are you talking about.  Combustion of natural gas to produce heat for what purpose?  Are you baking bread?  Or curing carbon fiber materials?  There are many tables of estimated flue gas temperature, but they are generally based upon loosely defined industry standard designs, which may or may not be applicable to your situation.  The easiest and most accurate way to determine the temperature is usually to measure it if access is available.  Also, where do you want to estimate the temperature of the flue gas?  At the oven outlet?  The stack outlet?
