- Increased reaction time, smaller coal particle size and increased reburn fuel fraction lead to higher NO reduction rate.
- The interior devolatilization of coal particle can increase the interior pressure which can produce expansion and fine crack leading to fragment.
- The results indicate the NO reduction rates are strongly dependent on the reaction time, the coal particle size and the reburn fuel fraction.
- Experimental results show that the pyrolytic weight loss drops noticeably with increasing coal particle size,with reducing pyrolysis temperature and the cone's rotational speed.
- The briquette strength is increased along with the feed coal particle size decreasing at the without binder and high-pressure briquetting process condition.
- The effect of feed coal particle size on strength of briquette is discussed when different briquetting process and rank of coalification coal are adopted.
