摘要
选取可再生且"碳零排放"的花生壳为原料,在热解装置中进行热解,得到终温分别为350℃,400℃,450℃,500℃和550℃的花生壳炭,并对花生壳炭进行工业分析、元素分析、发热量分析、燃尽率实验和热重实验,判断其是否满足高炉喷吹对燃料的要求.结果表明:五种不同热解终温花生壳炭的一些冶金性能达到了高炉喷吹燃料的质量要求,但灰熔点略低于规定温度范围,需要进一步探索优化方案.花生壳热解炭具有满足高炉喷吹冶金性能要求的可能性.
The renewable and＂carbon zero emission＂peanut shells were selected as raw materials for pyrolysis at 350 ℃,400 ℃,450 ℃,500 ℃ and 550 ℃ in tube setting furnace.Then five kinds of peanut shell carbons were analyzed by proximate analysis,ultimate analysis,calorific value analysis,burnout experiments and thermogravimetric tests to determine whether they met the requirements of blast furnace injection for fuels.The results show that metallurgical properties of peanut shell carbons of five different pyrolysis final temperatures reach the standard of stipulating in the blast furnace injection coal,but the ash melting point is under standard of process,which needed to further explore optimization scheme.In conclusion,peanut shell carbons have the possibility to meet the metallurgical properties requirements of injection in the blast furnace.
