The working principle of gas burner is introduced in detail: circuit fault, unstable power supply or lack of phase, and flameout in the process of formation. Treatment method: Electrician shall check the power supply and wiring. Failure of gas boiler combustor not to start press the start button for a long time, the gas boiler combustor does not start the external interlocking failure, and the external temperature or pressure control does not reach the lower limit of start; Check the temperature or pressure setting.

   When the internal interlock of gas boiler burner fails to pass, the air pressure is too high or too low, the air pressure switch is normally closed, the air valve mechanism is not in place, it will appear, and the inspection will be carried out step by step. If the program controller fails to reset, reset it again. Civil gas boiler combustor, civil stove, lighter, blowtorch, spray combustion device in engine, etc. all belong to civil granular gas boiler combustor.

   The utility model relates to a civil infrared gas boiler combustor, which has a gas boiler combustion shell, a microporous ceramic inner fire plate, a microporous ceramic outer fire plate, an air inlet pipe and an air mixing chamber of the microporous ceramic inner fire plate, an air inlet pipe and an air mixing chamber of the microporous ceramic outer fire plate. The microporous ceramic outer fire plate is a ring fire plate, and its front and back ends are flush with the plate surface of the microporous ceramic inner fire plate and are limited and supported by the combustion shell of the gas boiler.

   An air inlet is arranged between the microporous ceramic inner fire plate and the microporous ceramic outer fire plate, which is characterized in that the plate surface between the front and back ends of the microporous ceramic outer fire plate is composed of a concave surface located in the outer ring of the plate surface and a convex surface located in the inner ring of the plate surface, The contour shape and size of the plate surface between the front and back ends of the microporous ceramic outer fire plate in any section passing through the rotation axis of the microporous ceramic inner fire plate are the same.
