[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] The utility model provides a special steam boiler for burning corn cobs, such as Figure 1-Figure 3 As shown, it includes a boiler body 1, a lower furnace body 2 is installed at the bottom of the boiler body 1, a furnace 21 is arranged inside the lower furnace body 2 for burning fuel, a plurality of heat exchange tubes 11 are installed inside the boiler body 1 for heat exchange between flue gas and water, a plurality of riser tubes 3 are connected to the bottom of the heat exchange tubes 11 for eliminating the dead water area at the bottom of the boiler body 1, making it difficult for mud to deposit, so that the high temperature area on the upper part of the boiler body 1 can be well cooled, and bulging of the lower part of the drum is prevented, a water collecting pipe 6 is connected to the bottom end of the riser tube 3, a steam-water separator 12 is installed above the inside of the boiler body 1 for steam-water separation, an exhaust valve 13 is installed on the top of the steam-water separator 12 for gas discharge, a front smoke box 4 is arranged at one end of the boiler body 1, and a rear smoke box 5 is arranged at the other end of the boiler body 1 for flue gas buffering.
[0024] In this embodiment, a maintenance ladder 7 is installed on one side outer wall of the boiler body 1 for maintenance of the equipment.
[0025] Specifically, a sewage outlet 14 is provided at the bottom of one end of the boiler body 1 for sewage discharge.
[0026] Furthermore, a feeding port 22 is provided above and below one end of the lower furnace body 2 for adding fuel.
[0027] Furthermore, the riser pipes 3 are located at the inner wall of the lower furnace body 2 and are arranged at equal intervals to ensure that the inner wall of the boiler body 1 can be cooled.
[0028] Furthermore, a smoke exhaust pipe 51 is connected to the top of the rear smoke box 5 for exhausting smoke.
[0029] Furthermore, a drain pipe 15 is connected to the bottom of one end of the boiler body 1 , and a water inlet pipe 16 is connected to an outer wall of one side of the boiler body 1 .
[0030] Furthermore, the heat exchange tube 11 adopts a threaded smoke tube structure, and both ends of the boiler body 1 adopt an arched tube sheet structure.
[0031] Furthermore, an eight-shaped wall 23 is installed inside the boiler body 1 at the top of the lower furnace body 2 for centrally discharging the flue gas from the lower furnace body 2 into the boiler body 1 .
[0032] When the utility model of the corn cob-fired steam boiler is used, first, corn cob fuel is added into the furnace 21 through the feeding port 22 of the lower furnace body 2. As the fuel burns, the high-temperature flue gas generated rises in the furnace 21 and exchanges heat with the water in the boiler body 1 through a plurality of heat exchange tubes 11. During the heat exchange process, the heat of the flue gas is transferred to the water, so that the water is gradually heated and steam is generated. The riser 3 located at the inner wall of the lower furnace body 2 eliminates the dead water area at the bottom of the boiler body 1, making it difficult for mud to deposit, and ensures that the high-temperature area on the upper part of the boiler body 1 can be well cooled, preventing the lower part of the drum from bulging. The bottom end of the riser 3 is connected to the water collecting pipe 6 to effectively collect and distribute the water flow. Above the interior of the boiler body 1, the steam-water separator 12 separates the steam-water mixture generated, separating the pure steam from the water. The separated steam continues to rise and is discharged from the boiler body 1 through the exhaust valve 13 for subsequent use. The separated water returns to the boiler body 1 to continue to participate in the heat exchange. A front smoke box 4 and a rear smoke box 5 are provided at one end of the boiler body 1 for flue gas buffering and further heat exchange. The top of the rear smoke box 5 discharges the flue gas into the atmosphere through a smoke exhaust pipe 51.
[0033] In order to ensure the normal operation and maintenance of the boiler, an inspection ladder 7 is installed on the outer wall of one side of the boiler body 1 to facilitate the operator to inspect and maintain the equipment. At the same time, a sewage outlet 14 is provided at the bottom of one end of the boiler body 1 for regularly discharging impurities and dirt in the boiler. Throughout the process, the internal structure of the boiler body 1 is reasonably designed, especially the heat exchange tube 11 adopts a threaded smoke tube structure and the two ends of the boiler body 1 adopt an arched tube plate structure, which improves the heat exchange efficiency and structural stability. In addition, the setting of the eight-shaped wall 23 allows the flue gas to be discharged from the lower furnace body 2 into the boiler body 1 in a centralized manner, further improving the combustion efficiency and heat exchange effect.
