Abstract
A method of preventing exhaust gas from leaking out of a drying furnace is disclosed. In the method, the temperature of an exhaust passage and the temperature of a heater are measured, and turning on/off the heater is controlled in response to the measured temperatures. The present invention can be applied to all kinds of apparatuses having drying furnaces which are heated by heaters and thus generate the exhaust gas and can effectively prevent exhaust gas from leaking out of the apparatuses. Furthermore, the present invention can be more effectively applied to food waste disposers which heat food waste containing a large amount of water. In particular, the present invention is effective for circulation food waste disposers in which exhaust gas is condensed and re-supplied into a drying furnace as recirculation gas.
