Efficient fuel gas utilization device of steam generator

The invention relates to the technical field of steam generators, in particular to an efficient gas utilization device of a steam generator. The efficient gas utilization device comprises a box body, supporting legs are fixedly connected to the bottom of the box body, a bottom plate is fixedly connected to one ends of the supporting legs, a control panel is fixedly connected to one side of the box body, and a gas inlet pipe is inserted into one side of the box body. A fixing pipe is inserted into one end of the air inlet pipe, air guide pipes distributed at equal intervals are inserted into one side of the fixing pipe, and combustion heads distributed at equal intervals are inserted into the tops of the air guide pipes. According to the efficient gas utilization device, through the arrangement of a dispersing assembly and a descaling assembly, the combustion heads which are distributed in the box body at equal intervals can uniformly heat cold water, so that the temperature rise rate of the cold water is grea
