Problem of heat balance in Coal Boiler simulation --

2008-12-25 · In Fluent 6, I don't use a UDF for this - rather just use the input panel to specify that there is a heat source in the porous cells and then specify a constant source. The 389 MW, of course, is much to large of fraction for just the superheaters assuming a boiler with conventional superheaters, generating bank, economizer, etc.
