Gas-liquid mixed combustion nozzle assembly and combustion device

The utility model provides a gas-liquid mixed combustion nozzle assembly and a combustion device. Wherein an emulsifying and mixing chamber is formed in the fuel nozzle body, and an emulsifying and mixing liquid spraying hole connected with the emulsifying and mixing chamber is formed in the end part of the fuel nozzle body. And the fuel oil pipeline and the atomizing agent pipeline are arranged on the fuel nozzle body and are communicated with the emulsifying and mixing chamber. The fuel gas pipeline is arranged on the fuel nozzle body and penetrates through the emulsifying and mixing chamber, and a fuel gas nozzle is formed at the tail end of the fuel gas pipeline and located in the middle of the emulsifying and mixing liquid spraying hole. According to the technical scheme, the gas nozzle is used for jetting, gas pressure is high, flow is large, the influence of liquid fuel high-pressure jetting on gas fuel can be reduced to a great extent, and the risk of gas backfire is greatly avoided.
