摘要
以半焦焦粉为主要原料,采用冷压成型工艺制备型煤.重点研究了黏结剂、原料粒度和水分等因素对型煤性能的影响.结果表明,以有机黏结剂制备的型煤抗压强度最大,发热量高,但热稳定性较差;以无机黏结剂制备的型煤抗压强度低,发热量小,但热稳定性好;采用复合黏结剂可以取长补短,发挥出最佳黏结效果.
A kind of briquette was prepared with the semi-coke breeze as raw material by cold-pressed process. It was studied that the binder, particle size of raw material, moisture on the impact of briquette properties. The result shows that the prepared briquette with organic binder has the largest compressive strength and the larger calorific value, but lower thermal stability quite the contrary, the prepared briquette with inorganic binder of the least compressive strength, the less calorific value, but higher thermal stability, composite binder can use each other, it can play the best results.
