Abstract

A flat-flame pulverized coal gasification technology is presented and its test results on a 3 t/d gasification test facilities are discussed. The test results show that the performance data of flat-flame gasification technology is better than the traditional top-placed single-burner technologies, and the test facility is in stable operation during the test periods. Computational fluid dynamics (CFD) tools are also employed to investigate the flow field characteristics of the flat-flame gasifier. It is revealed that, the flat-flame burner enables higher turbulent intensity and enhances the turbulent mixing between coal particles and oxidant. The overall gasification reaction rate is increased by abovementioned effects. Preliminary test results and simulation analysis validates the technical feasibility of flat-flame gasification technology and it is ready for scale-up for industrial demonstrations.
