Abstract
The present disclosure provides a silicon nitride ceramic heating and ignition device for a granular fuel barbecue oven, including a combustion chamber and a fixing pipe. An outer wall of the combustion chamber is welded to one end of the fixing pipe, the fixing pipe is communicated with an interior of the combustion chamber, and air inlet holes and air flow holes are defined in the two sides of the fixing pipe. One end of the fixing pipe is fixedly connected with a stainless steel sheet bending support, and the heat dissipation ceramic flange sleeve and one end flange port of the fixing pipe are connected with a boss positioning center. An inner cavity of the heat dissipation flange ceramic sleeve is bonded with the silicon nitride ignition rod.
