Described deflection cone 8 is by reinforcement welding in the inner side of horn mouth 9.
Circular hole is densely covered with the conical surface of described deflection cone 8, the air in the outside of horn mouth 9 can be entered by described circular hole
The inner space of horn mouth 9, so as to improve the success rate of the igniting of igniter 5.
The utility model is by setting horn mouth 9 in the port of export of Gas Pipe 4 and being provided with text around Gas Pipe 4
The high speed ajutage 3 of venturi 7, can promote the mixing of air and combustion gas, so as to improve the combustion rate of combustion gas, and improve igniter
5 ignition success rate, and then increase thermal effect is realized, reduce the purpose of discharged nitrous oxides.
