The invention relates to the technical field of garbage incineration boilers, in particular to a garbage incinerator water cooling furnace wall structure. The garbage incinerator water cooling furnacewall structure is simple, convenient to manufacture and install and low in cost. The garbage incinerator water cooling furnace wall structure comprises a hearth. A drying fire grate, a combustion fire grate and a complete combustion fire grate are arranged at the bottom of the hearth and are sequentially arranged. An air cooling furnace wall structure is adopted at the position of the drying firegrate, a water cooling furnace wall structure body is adopted at the positions of the combustion fire grate and the complete combustion fire grate, and the air cooling furnace wall structure and thewater cooling furnace wall structure body are connected through a nonmetal expansion joint. The hearth is defined by the air cooling furnace wall structure, the water cooling furnace wall structure body, a front arch water cooling wall and a rear arch water cooling wall. The water cooling furnace wall structure body is composed of film type water cooling walls. The first film type water cooling wall at the position of the complete combustion fire grate, the front arch water cooling wall and the rear arch water cooling wall are connected with a first header located at the middle portion of thehearth, the second film type water cooling wall at the position of the complete combustion fire grate is connected with a second header located at the outer portion of the rear arch water cooling wall. The second header is parallel to the outer wall of the lower hearth, and the second header is connected with a third header located at the position of a complete combustion chamber.
Description
Technical field [0001] The invention relates to the technical field of garbage incineration boilers, in particular to a water-cooled furnace wall structure of a garbage incinerator. Background technique [0002] With the development of the economy, the country has paid more and more attention to urban waste treatment and energy saving and emission reduction. All cities are vigorously building waste incineration boilers to treat the increasing amount of municipal waste. In the waste incineration boiler, the furnace wall between the lower part of the furnace and the grate needs to be cooled. At present, air-cooled furnace walls are used. Due to its own reasons, the air-cooled furnace walls are heavy and require special air cooling pipelines. The system is difficult to manufacture and has a large manufacturing workload. In the actual installation process, the sealing problem of the adjacent air-cooled wall needs to be considered, and the cost is high. Summary of the invention [000...
