摘要： PROBLEM TO BE SOLVED: To provide a combustion heater control device capable of easily continuing combustion even at a return of fuel supply after temporary interruption.
SOLUTION: This combustion heater control device has a fuel supply means 180 for supplying fuel into a combustion chamber 132 through a fuel supply passage 134; a heating means 136 for heating to ignite fuel; a combustion state detecting means 163 for detecting the combustion state of the fuel; and a control device 200 for controlling the operation of the fuel supply means 180 and heating means 136 according to detection signals from the combustion state detecting means 163 to heat an external fluid to a prescribed temperature with combustion gas. The combustion heater control device is provided with a first decision value Tgoff1 for determining a misfire sign state prior to determining the combustion state as a misfire state based on the prescribed value Tgoff of the detection signal in the case an unfilled state of fuel occurs in the fuel supply passage 134 to temporarily stop fuel supply, and the heating means 136 is operated when the combustion state is the misfire sign state.

摘要： PROBLEM TO BE SOLVED: To prevent any explosive ignition-combustion, and to shorten the ignition start time.
SOLUTION: In the re-ignition, the inside of a combustion unit 31 is heated by a glow plug 37 while feeding air to the combustion unit 31 in a state that fuel feed to the combustion unit 31 is stopped, and the fuel feed to the combustion unit 31 is re-started after checking that a pilot flame is generated. Therefore, a combustion apparatus 30 can be transferred to a steady combustion control mode earlier than to a conventional mode in which the re-ignition remaining heat time ΔT3 is fixed, and the generated pilot flame can be reliably grown. The combustion apparatus 30 can be reliably ignition-started while preventing any explosive ignition-combustion, and the ignition starting time can be shortened.
