After the curved water pipe 4 has fully radiated heat exchange and water supply, the high-temperature flue gas flows from the inlet of the curved smoke pipe 3 through the curved smoke pipe 3 for convective heat exchange water supply, and the flue gas is concentrated from the outlet of the curved smoke pipe to the smoke chamber of the dust removal base 8 of the boiler for the second stage. First gravity sedimentation dust removal, after the first gravity sedimentation dust removal, the low-temperature flue gas flows through the horizontal flue 14 into the dust removal chamber 15 for the second gravity sedimentation dust removal, and then is discharged into the atmosphere through the chimney. When the hot water boiler is working, because the water contained in the boiler continuously absorbs heat, when the water reaches the specified pressure and temperature, the heat supply valve is opened, and the circulation pump on the water inlet device is started to supply heat to the heat users. When the steam boiler is working, because the water contained in the boiler is continuously absorbing heat, when the water saturation temperature is reached, the water in the boiler starts to vaporize and generate high-temperature steam. When the steam reaches the working pressure of the boiler, open the heating valve 20 Steam households supply steam. Therefore, the boiler can be designed as a vertical water-fire tube energy-saving and environment-friendly hot water boiler and a vertical water-fire tube energy-saving and environment-friendly steam boiler. The effect of hand hole 9 and manhole 11 is mainly to make inspection, maintenance and cleaning dirt in the boiler operation process, and the effect of blowdown device 23 is mainly to facilitate the blowdown in the boiler operation process.
