| description | The BF(blast furnace) process has become the most powerful pointcut for energy conservation and emission reduction in the iron and steel industry. Few researchers have studied the composition and distribution of bosh gas with co-injection of pulverized coal and natural gas under the oxygen-enriched blast. In this paper, a 3D model of pulverized coal(PC) and natural gas(NG) synergistic combustion was established with a new method of assessment of the utilization rate of bosh gas by using the method of computational fluid dynamics(CFD). The distribution and utilization rate of bosh gas were systematically studied, and the results have shown that when the O2 concentration in the hot blast increased from 27 % to 32 %, the burnout rate of PC increased by 5.08 percentage points, the maximum temperature in the raceway increased by 125K, the residence time of PC particles increased by 0.0017s, the utilization rate of bosh gas increased 2.1 percentage points. |
