[0003] After searching, the Chinese patent with application number "201921347066.2" is specifically an energy-saving steam generator, including a main body, heat dissipation fins, spiral tubes, disc tubes, a second water pump and a hollow interlayer. A combustion chamber is installed under the main body, and a gas pipeline is connected to the left side of the combustion chamber. A first solenoid valve is installed on the gas pipeline. A plurality of heat dissipation fins are evenly distributed from top to bottom on the outer walls of the heating chamber, and a spiral tube is installed in the hollow interlayer; a second smoke exhaust pipe is connected to the lower left side of the spiral tube, and a water tank is installed on the left side of the main body; a second water pipe is installed under the right side of the main body, and the upper part of the second water pipe is connected to the upper part of the main body. A plurality of nozzles are evenly distributed below the part of the second water pipe located above the main body.
