The oil-burning roller hearth kiln is quite different from the gas-burning kiln. In general, any burner cannot be designed in the preheating zone of a heavy-oil-burning roller hearth kiln to control the temperature and drying curve of preheating. For fast-firing and saving energy, however, a pre-drying zone can be designed in front of the preheating zone using the waste heat of the flue gas from the preheating zone to dry and preheat the ceramic bodies when the water content of the bodies becomes too high. The reasonable structure of a pre-drying zone and a simple computer-controlled system has been suggested by using a computer analog of gas flow and head transfer.
