Heat transfer in industrial furnaces. Annual report, April 1992-March 1993

The thermal system model for an indirectly-fired continuous furnace has been completed by coupling a one-dimensional radiant tube model with the furnace space model. For a given furnace geometry, it is now possible to specify the firing rates in individual radiant tubes and to predict the resulting load temperature profiles and heat transfer to the load while also calculating the exhaust gas temperature from each tube. Sensitivity studies have been performed, bu the model has not been validated because of lack of appropriate test or operating furnace data.
