摘要
Abstract
Characteristics of morphology,packing and flow resistance of large size sinter particle and its packed bed have been studied experimentally.It has been proved that particle morphology has real effect on packing feature in flow and pressure drop or resistant coefficient.The results show： firstly,the smaller the particle size,the higher particle sphericity;secondly,it has different porosity distribution for the same group of particle according to imagine analysis result;and the thirdly,porosity distribution has some difference in space which leads to odd resistance coefficient or pressure drop.In the maximum gas velocity of the experiment study,a linear relationship between pressure drop and bed height was seen,but it did not exist when operation gas velocity decreases.关键词
