| Abstract: | Based on the principle of endothermic reactions of carbon with H2O and CO2,the two-stage coal gasification process with highly-efficient chemical heat recovery was exploited to recycle the heat.This process can make up the deficiency of the existing entrained-flow gasification process.On a laboratory-scale hot testing installation of heat reaction,the influence of particle-diameter on reaction efficiency,the temperature profile of the second stage gasifier,and the distribution of carbon residue yield in sla... |
