POT TYPE COMBUSTION UNIT AND METHOD FOR CONTROLLING POT TYPE COMBUSTION UNIT

摘要

PROBLEM TO BE SOLVED: To restrict deflagration under user's erroneous operation (re-starting just after occurrence of combustion fan error) at a pot type combustion unit.SOLUTION: The pot type combustion unit comprises: a pot type burner formed into a cylindrical shape comprising a bottom part; a fuel oil supply part for supplying fuel oil to the pot type burner; a heater disposed at the bottom part of the pot type burner to perform a pre-heating and ignition; a combustion fan for supplying air to the pot type burner; abnormal state detecting means for detecting abnormal state occurring at the combustion fan; stopping means to cause memory means to store a prescribed error code when the abnormal state is detected to stop an operation at the fuel oil supply part; error code determination means (S2, S4) for determining whether or not the error code is stored in the memory means; and waiting means (S8) for making a turned-on state of the heater after waiting until the temperature becomes a value lower than a prescribed allowable temperature when the result of determination is YES.SELECTED DRAWING: Figure 3
