Abstract

In the general frame of energy saving, environment protection and the concept of circulareconomy, the fundamental research on the sintering technology with super deep bed,achieving energy saving and emission reduction, was carried out. At first, thecharacteristics of the process and exhaust emission in the sintering with super deep bedwas mastered through the study of the influence of different bed depths on the sinteringprocess. Then, considering the bed permeability and the fuel combustion, their influenceon the sinter yield and quality, their potential for energy saving and emission reductionwas studied. The results show that the improvement of the bed permeability and of the fuelcombustibility respectively and simultaneously, leads to an improvement of the sinteringtechnical indices, to energy saving and emission reduction in the condition of super deepbed. At 1000 mm bed depth, and taking the appropriate countermeasure, it is possible todecrease the solid fuel consumption and the emission of CO2, SO2,NOx by 10.08%, 11.20%, 22.62% and 25.86% respectively; and at 700 mm bed depth, it ispossible to reduce the solid fuel consumption and the emission of CO2,SO2, NOx by 20.71%, 22.01%, 58.86% and 13.13% respectively. This researchprovides the theoretical and technical basis for the new technology of sintering withsuper deep bed, achieving energy saving and reduction of emission.
