It should be noted that the condenser device 10 and the smoke box 4 are detachable and can be replaced and disassembled according to needs. The ring tube assembly includes a furnace water-cooled wall ring tube, a high-temperature section ring tube and a low-temperature section ring tube arranged from top to bottom.

[0020] Specifically, the condenser device 10 includes a condenser shell, the top of the condenser shell is set as a smoke outlet 14, the bottom of the condenser shell is set as a smoke inlet 15, the smoke inlet 15 is connected to the smoke box 4, and a temperature pipe 13 is set on the smoke inlet 15. It should be noted that the setting of the temperature pipe 13 will facilitate the detection of the smoke temperature of the smoke inlet 15.

[0021] Specifically, a fin tube 16 is arranged in the condenser shell, and the fin tube 16 is connected to the inner wall of the condenser shell through a tube sheet 17. An insulation layer 18 is arranged between the fin tube 16 and the condenser shell, and a plurality of angle steels 19 are arranged in the insulation layer 18. An inlet manifold 11 and an outlet manifold 12 are arranged at the upper and lower ends of the condenser shell, respectively, and the inlet manifold 11 and the outlet manifold 12 are connected to the fin tube 16, respectively. A condensation water delivery trough 20 is arranged below the fin tube 16, and the condensation water delivery trough 20 is arranged in the bottom end of the condenser shell. It should be noted that the arrangement of the angle steel 19 will enhance the overall strength of the condenser shell to meet the use requirements.

[0022] Specifically, the water inlet manifold 11 is connected to the circulating water pump, the water outlet manifold 12 is connected to the water jacket water inlet 7, the mosquito coil water inlet 8 is connected to the water supply pump, and the circulating water pump and the water supply pump are both connected to the water tank.

It should be noted that the setting of the insulation layer 18 will reduce energy loss and improve its performance.

[0024] The working principle of this specific implementation method is: first, water is pumped through the mosquito coil water inlet 8 through the water pump, and then evenly divided into two ways through the tee to enter the low-temperature section ring pipe, then enter the high-temperature section ring pipe, and finally enter the furnace water-cooled wall ring pipe. The burner 3 works, and the water is gradually vaporized by heat during the process to produce a steam-water mixture, which enters the unheated steam-water separator for efficient separation. At the same time, the inner cavity formed by the furnace water-cooled wall ring pipe is the combustion chamber, and the gas is ignited by high pressure to form an ignition flame. The main fuel natural gas and air are fully premixed before entering the combustion chamber, and the premixed gas enters the combustion head made of metal fiber fabric. The combustion flame radiates and heats the surrounding furnace water-cooled wall ring pipes on the one hand, and on the other hand The high-temperature flue gas generated by combustion flows downward, passes through the gap between the annular tube components for convection heat exchange, and is discharged from the smoke box 4 into the smoke inlet 15, and is discharged from the smoke outlet 14 through the fin tube 16. During the process, the circulating water pump works to transport water to the fin tube 16 through the water inlet header 11, and enters the cooling water jacket through the water outlet header 12 and the water jacket inlet 7, and then returns to the water tank. The condenser device 10 is connected to the smoke outlet of the steam generator body 1 to further absorb the tail flue gas for waste heat recovery. Under the action of the water pump, the feed water of the steam generator is injected from the inlet of the lower low-temperature section annular tube, and flows upward along the tube to the furnace water-cooled wall annular tube under the drive of pressure, forming a countercurrent with the flue gas, thereby ensuring a higher heat exchange efficiency.

[0025] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
