| Abstract | Abstract A new type of pressurized entrained-flow pulverized coal gasification technology has been developed by ECUST. It is characterized with four nozzles symmetrically disposed on the upper part of a gasifier. The effects of operation conditions on gasification, N 2 as carrier gas with middle pressure superheated (MP SH) steam, CO 2 as carrier gas with MP SH steam and CO 2 as carrier gas without MP SH steam, respectively, have been tested in the pilot plant. The carbon conversion of all gasification schemes is larger than 99%. For N 2 as carrier gas, the volume fraction (Dry) of CO + H 2 is larger than 90% (v). For CO 2 as carrier gas, the volume fraction (Dry) of CO + H 2 is larger than 92% (v) with MP SH steam and larger than 95% (v) without MP SH steam. At the same time, based on Gibbs energy minimization principle, the pulverized coal gasification system model was built. The simulation results well matched the pilot-trial data under different operation conditions. The model can be used for the design, assessment, and improvement of the entrained-flow coal gasification system. |
