专利汇可以提供Method for incinerating industrial wastage专利检索，专利查询，专利分析的服务。并且There is disclosed a method for incinerating combustible industrial wastage containing organic nitrogen compounds of a peptide bond, cyan radical, etc. by using a so called fluidized bed incineration furnace. This method uses steps of supplying, the aforesaid wastage together with combustible materials abundant in carbon content, such as pulverized coal, heavy oil, etc., in the fluidized bed to thereby maintain the interior of the fluidized bed in a reductive atmosphere, while reducing nitrogen oxide produced from the combustion of the wastage, whereby nitrogen oxide may be removed as innocuous nitrogen from waste-gas or stack gas.，下面是Method for incinerating industrial wastage专利的具体信息内容。

权利要求

1. IN A METHOD FOR INCINERATING COMBUSTIBLE INDUSTRIAL WASTAGE CONTAINING ORGANIC NITROGEN COMPOUNDS IN A FLUIDIZED BED, WHEREIN AIR FOR USE IN COMBUSTION IS BLOWN INTO A FURNACE FROM BELOW TO FLUIDIZED NON-CONBUSTIBLE FLUIDIZED MEDIUM PLACED WITHIN SAID FURNACE, FOR FORMING A FLUIDIZED BED, AND AT THE SAME TIME SAID COMBUSTIBLE INDUCTRIAL WASTAGE IS SUPPLIED INTO SAID FURNACE FROM THE UPPER PROTIONS THEREOF, WHICH FURNACE HAS BEEN PREHEATED TO A TEMPERATURE ABOVE THE COMBUSTION TEMPERATURE OF SAID COMBUSTIBLE INDUSTIAL WASTAGE WHICH IS TO BE INCINERATED IN SAID FLUIDIZING BED, THE IMPROVEMENTS COMPRISING THE STEPS OF SUPPLYING COMBUSTIBLE FUEL MATERIAL ABUNDANT IN CARBON CONTENT WITH SAID COMBUSTIBLE INDUSTRIAL WASTAGE INTO SAID FLUIDIZED BED; SIMULTANEOUSLY MAINTAINING THE INTERIOR OF SAID FLUIDIZED BED IN A REDUCTIVE ATMOSPHERE AND AT A TEMPERATUE HIGHER THAN THE COMBUSTION TEMPERATURE OF SAID FUEL MATERIAL AND THE COMBUSTION TEMPERATUE OF SAID COMBUSTIBLE INDUSTRIAL WASTAGE; INCINERATING SAID COMBUSTIBLE INDUSTRIAL WASTAGE IN THE REDUCTIVE ATMOSPHERE IN SAID FLUIDIZED BED AND PRODUCING NITROGEN OXIDES FROM THE COMBUSTION OF THE

2. A method for incinerating industrial wastage as defined in claim 1, including the step of providing said fluidized medium particles as cement clinker particles, which contain Fe2O3, Al2O3, Cr2O3 and MnO as cataylsts.

3. A method for incinerating industrial wastage as defined in claim 1, including the further step of providing said fluidized medium particles as chromium ore particles.

4. A method for incinerating industrial wastage as defined in claim 1, further including the step of providing said fluidized medium particles as manganese ore particles.

5. A method for incinerating industrial wastage as defined in claim 1, wherein the resultant combustion gases obtained from the prior steps are mixed with air and maintained at a temperature above the combustion temperature of the combustible gases and below 1,000* C for completing the combustion of the combustible gases without producing nitrogen oxides from the nitrogen gas.

6. A method for incinerating industrial wastage as defined in claim 5, wherein the resultant gases from the previous steps are at least in part supplied with the air blown into the furnace to fluidize the non-combustible fluidizing medium placed within said furnace and further to control the oxygen content of the fluidizing gas.

7. A method for incinerating industrial wastage as defined in claim 1, including the further step of automatically controlling the quantity of combustible fuel material abundant in carbon content that is supplied to the fluidized bed and simultaneously automatically controlling the oxygen content of the fluidizing air blown into the furnace from below, in response to the flow of industrial wastage into the furnace and the temperature of the fluidized bed.
