摘　　要：用煤气化联产合成氨工艺中产生的各种废水制备水煤浆,研究成浆性、流变性及稳定性,并在水煤浆气化炉上应用。结果表明:煤气化联产合成氨工艺中产生的洗气水、硫磺水及外来工业废水均对成浆有促进作用,而碳化水不利于成浆;洗气水的假塑性流体特征最明显,硫磺水及工业废水次之,碳化水流变性较差;几种废水在静置1个月后均未产生硬沉淀,具有良好的稳定性;废水水煤浆气化联产合成氨具有良好的环境效益和经济效益。Water-coal-slurry has been prepared from various kinds of wastewaters generated from synthetic ammonia process in coal gasification combined production.The slurrying ability,rheology property and stability of the water-coal-slurry have been investigated and applied to the gasification burner of water-coal-slurry.The results show that all the gas washing water,sulfur water and external industrial wastewater produced from the synthetic ammonia pro-cess in coal gasification combined production have auxo-action on slurrying ability,while the carbonized water has a negative influence on slurrying.The pseudo-plastic fluid characteristic of gas washing water is the most obvious one,and the sulfur water and industrial wastewater are the second.The rheological property of carbonized water is com-paratively poor.These kinds of wastewaters do not produce hard sediment after standing for a month,and have good stability.Thus,the synthetic ammonia in wastewater water-coal-slurry gasification combined production has good en-vironmental and economic benefits.
