专利汇可以提供Garbage incinerator and method of operation专利检索，专利查询，专利分析的服务。并且A system for disposing of garbage and gaining useful heat output from controlled burning of the garbage is provided and is particularly adapted for decentralized locations in a community. The garbage is dumped into a feed hopper and piled to a substantial depth with the forward face of substantial crosssectional area being acted upon by rotating shredders; the garbage being continuously fed forward by the endless belt support at the bottom of the hopper. A second series of shredders serves to completely shred and masticate the garbage into fine particles and project the same into a combined compressing and pulverizing station. Continuous ignition is provided by a heatretaining wall immediately downstream. Solid particles, glass and metal are removed by transverse conveyors at critical locations along the system. Computer control of the operating components and auxiliary fuel injection maintains full efficiency in the incinerator chamber. Heat exchange means is provided for useful heat output with expansion and scrubber chambers immediately downstream thereof. Steam is injected to move the relaxed gaseous products and to precipitate out minute solid products; the gaseous products being forced to the bottom of the unit to assist the precipitation and to thus minimize air pollution. A melting cupola for glass or other thermoplastic material receives heat from the incinerator chamber with continuous casting of such byproducts and cutting into blocks.，下面是Garbage incinerator and method of operation专利的具体信息内容。
