Abstract:

According to the refractory brick types of various grate incinerators in China,the refractory bricks were classified into square brick,pulled anchor brick,mosaic air-cooled brick,drop wall top brick,starting brick,air outlet brick,anchor brick,etc.By categorizing summary and design optimization,the refractory brick type design and dimensional characteristics of the grate incinerator walls were standardized.In combination with the expansion design needs and the furnace wall structural features,the furnace walls were divided into several modular design units,each unit is an independent and interconnected whole.Practice proved that the brick type standardization and the modular design of the furnace wall were suitable for the design of various grate furnace walls,which significantly improved production and construction efficiency,reduced costs,and shortened the stocking and maintenance cycle.Meanwhile,the multi-layer anchoring flexible design and independently air-cooled design of the local high-temperature furnace wall further improved the stability of the furnace wall and reduced the frequency of furnace shutdown for ash removal,significantly extending the operating rate of the incinerator.

Key words: grate incinerator, brick type standardization, modularization of furnace wall, combustion zone, air-cooled furnace wall
