The invention relates to a rotary fan mixer of a blast type combustor. A combustion-supporting gas inlet, a combustible gas inlet and a gas supply hole arranged at the head of the combustor are arranged on the wall of a gas mixing chamber of the rotary fan mixer, a rotary fan and a rotary fan supporting shaft are arranged in the gas mixing chamber, the combustible gas inlet is arranged in the rotary fan supporting shaft, the rotary fan supporting shaft is fixedly connected with the wall of the gas mixing chamber, and the rotary fan is installed on and rotatably matched with the rotary fan supporting shaft and is limited by an axial spring collar. When combustion-supporting gas and combustible gas push the rotary fan to fast rotate and stir after simultaneously entering the gas mixing chamber, the combustion-supporting gas and the combustible gas are instantly, uniformly and fully mixed, therefore, the combustion heat efficiency of the blast type combustor is dramatically enhanced, and simple structure as well as easy manufacture, application and popularization are realized. The blast type combustor is mainly applied to combustion fields of industrial (oil) gas-fired boilers, commercial (oil) gas-fired boilers, civil large (oil) gas-fired boilers, Chinese cooking hotplates, pulverized coal boilers and the like.
Description
Technical field: [0001] The invention relates to a rotary fan mixer for a blower burner. When it works, the combustion-supporting gas and the combustible gas enter the gas mixing chamber at the same time, and then push the rotary fan to rotate and stir the gas quickly in the gas-mixing chamber, so that the combustion-supporting gas and the combustible gas are combusted It is a blower type burner rotary fan mixer that can be mixed evenly and fully in an instant, so that the gas can be fully burned, and the thermal efficiency of combustion can be significantly improved. Blast burners are mainly used in combustion fields such as industrial (oil) gas boilers, commercial (oil) gas boilers, civil gas (oil) gas boilers, Chinese food stoves and pulverized coal boilers. Background technique: [0002] At present, the gas mixing methods of burners at home and abroad mainly include: parallel airflow mixing, intersecting airflow mixing, swirling airflow mixing, high-pressure jet airflow ...
