摘要：PURPOSE:To emit an alarm so that tar baking combustion is performed when much tar etc. is accumulated in an evaporating chamber by detecting whether combustion state is abnormal or not, comparing an ionic current threshold value io due to a present abnormal combustion value if measured by an ionic current detector. CONSTITUTION:Combustion is started, signal B is inputted to a microcomputer 15 and the time from the start of combustion begins to be counted by a firmware. After the ionic current value is stabilized the ionic current value if is inputted to the decision device of the computer 15. Comparing the value if with the value io or the threshold value of the ionic current due to abnormal combustion preset in the memory device, the combustion is decided to be an abnormal combustion due to accumulation of tar when the value if is smaller than the value io, a signal C is outputted to illuminate the light emitting diode 16 as an alarm device. Accordingly the state of abnormal combustion need not be decided visually. When the amount of accumulated tar in an evaporating chamber is poor, tar baking combustion is possible and the removal of tar is possible in a short time.
