- 摘要:以污泥添加量为2%(干基)白泥添加量为0.3%(干基)所制得的污泥型煤为研究对象,以白泥添加量为5.5%的白泥型煤作为参照,考察了污泥型煤的气化特性和二次污染。研究结果表明,在1100℃以上高温下,污泥型煤的气化速率比白泥型煤高50%以上;污泥型煤的灰渣软化温度达1440℃,能满足合成氨气化要求;污泥型煤无二次污染,其气化成分符合合成氨原料气的要求。
- Abstract:Sewage sludge briquette made of 2%(dry basis) sewage sludge,0.3% white earth, and coal powder was studied under conditions of briquette similar to modeling and gasificaition for briquette on ammonia synthesis.Briguette with white earth was taken as a reference.The results showed that rate of gasification of sewage sludge briquette was 50% higher than that of briquette of white earth at 1100℃.Ash melting point of sewage sludge briquette reached 1440℃ which satisfied the requirement of gasification of ammonia synthesis.Results showed that no pollution took place in these processes,and the gas generated can meet the demand of ammonia synthesis.
