Abstract

A flat-flame pulverized coal gasification technology is presented and its test results on a 3 t/d gasification test facility are discussed. The test results show that the performance of flat-flame gasification technology is better than the traditional top-placed single-burner technologies, and the test facility is running stably during the test periods. 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. When the mass ratio of O2/coal is 0.8, the carbon conversion, volume fraction of efficient syngas and cold gas efficiency of flat-flame burner were respectively 96.7%, 88.6% and 82.1%, which are completely better than single-burner gasification. Preliminary test results and analysis validates the technical feasibility of flat-flame gasification technology and it is ready for scale-up for industry-scale demonstrations.
