"Where does all that heat go?" Heat balances are the foundation for an engineer to identify the opportunities for possible heat savings. There are several areas where heat could possibly be saved to make a kiln operate more efficiently in matters of energy consumption. Some of these potentials are: Lower kiln exit gas losses by:
