摘要：

As a new kind of low NOx combustion technology, micronized coal reburning has several advantages over conventional technology such as higher combustion efficiency and higher NOx reduction efficiency. Through tests, the combustion performance of micronized coal has been studied. Experimental results indicate that compared combustion of pulverized coal with normal particle size the combustion performance of micronized coal has been remarkably improved, the ignition index obviously decreased and burn-out ratio raised. Therefore, if micronized coal is served as reburning fuel, it can be ignited and burned out in shorter time. Hence, the burnout time of micronized coal is shorter than that of normal sized coal. so, it can solve the problem of shorter residence time due to fuel-staged combustion, which causes combustion efficiency reduced.
