专利汇可以提供Method for the disposal of garbage by multi-stage thermal decomposition专利检索,专利查询,专利分析的服务。并且In a method for the disposal of garbage by thermal decomposition, garbage charged into a first incinerator is thermally decomposed by external heat requiring no oxygen to obtain generated gas with high calorific value. The whole quantity of said generated gas is introduced into a second incinerator. Garbage is charged into said second incinerator in a quantity about four times that of the garbage charged into said first incinerator, and the whole quantity of said generated gas introduced from said first incinerator is burnt with pure oxygen supplied in an amount corresponding to the theoretical quantity of oxygen necessary for this combustion. The garbage charged into said second incinerator is thermally decomposed by the resulting combustion heat to obtain generated gas with high calorific value in a quantity about four times that of the generated gas obtained in said first incinerator. The number of incinerators is increased when necessary, and thermal decomposition of garbage is carried out in additional incinerator(s) in the same manner as in said second incinerator, whereby the quantity of disposed garbage and the quantity of generated gas are increased in the geometrical series. Generated gas obtained from the final incinerator is externally used as a heat source, but part of said product gas is fed back as a heat source necessary for said incinerators.,下面是Method for the disposal of garbage by multi-stage thermal decomposition专利的具体信息内容。

1. A method for the disposal of garbage by multi-stage thermal decomposition, characterized by: thermally decomposing garbage at the first stage by external heat requiring no oxygen; and thermally decomposing garbage at the second and following stages by combustion heat, said combustion heat being generated by combustion of the whole quantity of generated gas obtained by the thermal decomposition of garbage at the stage directly before the relevant stage with pure oxygen supplied in an amount corresponding to the theoretical quantity of oxygen for this combustion.
2. The method of claim 1, wherein said thermal decomposition of garbage comprises three stages.
3. The method of claim 1, wherein said thermal decomposition of garbage at said first stage is applied by external heat generated by an electric heating element.
4. The method of claim 2, wherein said thermal decomposition of garbage at said first stage is applied by external heat generated by an electric heating element.
