Bridgewall Temperature
- Thread starter padovano
- Start date
If this is a direct fired process furnace you might be able to assume a constant gas temperature (calculate heat release and flue gas mass) and then add conduction (fourier), convection (sieder-tate) and radiation (good luck).
The simplest method would be to get your hands on empirical correlations such as the Lobo-Evans data and make some assumptions about what's going on internally (flux rate etc).

has a little bit on the subject. I use curves for this and find theoretical calculations to be inaccurate...too many assumptions necessary whereas a bridgewall-flux curve results in accurate data fast.
