Research On Co-combustion And Co-pvrolvsis Characteristics Of The Drug Residues And Co-combustion And Coal In Fluidized Bed

The amount of hazardous waste increase as the development of the economy. It provides a way for the incineration of hazardous waste that the high-temperature environment of the power boiler (fluid ized bed. pulverized coal,etc.) and the thermal energy from the hazardous waste incineration can partially alternative fossil fuels, which will bring obvious economic benefits. So it is necessary to study the the key technology and the control technology system of environmental risk of the co-combustion of hazardous waste in the high-temperature of the power boiler.The paper firstly summarized the control standards of hazardous waste incineration and analysis the shortcomings of the domestic standard and make recommendations for improvement.The paper make the nitrobenzene dregs as raw material, the similarity of thermal decomposition characteristics was be confirmed in the dregs combustion and pyrolysis conditions by TG-FTIR. In the combustion process, it is conducive to the ahead release of the nitrobenzene dregs volatile when add bituminous coal to the dregs; When the ratio of the coal is greater than0.4, the sample has been unable to complete the incomplete combustion because of the interaction of pulverized coal and the dregs; and the co-firing of the drags and coal affects the ignition point. In the pyrolysis process, it is beneficial to the the dregs volatile release with the presence of more bituminous coal when the ratio of coal is greater than0.4; The presence of bituminous coal is conducive to release of the dregs’volatile, but there is a large negative impact to the pyrolysis conditions of the mixture as a whole.The paper gives one general formula can be used to calculate the waste element content limit in the hazardous waste which is co-combusted.
