Abstract: Refuse containing combustible components of variable caloric content is completely burned in a furnace having a vertical shaft for a combustion zone and a grate through which molten incombustibles and gaseous products of combustion are discharged downward into a pit. Annular streams of preheated air are injected inwardly and downwardly into the mass of refuse on the grate. Gaseous combustion products in the pit are continuously analyzed for the presence of free oxygen or incompletely burned combustibles. Combustion air is caused to travel through a thinner layer of refuse by injecting it at a lower point if combustion is not complete, or through a thicker layer of refuse by injection at a higher level if excess free oxygen is present. Regulation of the level of injection is achieved by control means connected to the analyzer and to valves in the air inlet lines.

Abstract translation: 含有可变热量的可燃成分的垃圾在具有用于燃烧区域的竖直轴和炉篦的炉中完全燃烧，通过该炉排将熔融不可燃物和燃烧气体产物向下排放到坑中。 环形的预热空气流向内和向下注入炉排垃圾。 连续分析坑中的气态燃烧产物是否存在游离氧或不完全燃烧的可燃物。 如果燃烧不完全，燃烧空气通过将其注入较低点，或者如果存在过量的游离氧，则通过较高级别的较高水平的较高层的垃圾将其喷射通过更薄的垃圾层。 通过连接到分析仪的控制装置和进气管线中的阀门来实现对喷射水平的调节。
