摘要:

根据多喷嘴对置式水煤浆加压气化装置投料以来出现的渣口堵塞、洗涤冷却水管堵塞、气化炉合成气出口积灰堵塞、锁斗冲洗水罐液位反弹和高压煤浆泵垫缸等常见问题,总结出简易的判断方法并提出相应的处理措施。经不断攻关、改进,装置实现了105%负荷常态化运行,碳转化率由98%提高至99%。

Abstract:

In connection with common problems of multi-nozzle coal-water slurry pressurized gasifier since start-up, such as slag notch blocking, scrubbing-cooling water pipe blocking, dust deposition blocking at outlet for syngas from the gasifier, rebound of liquid level of lock hooper washing water tank and high-pressure coal slurry pump trouble, simple adjustment methods are summed-up and relevant handling measures are suggested. After continuous tackling key problems and improvement, the normalizing operation at 105% load of the plant is realized, carbon conversion ratio is increased from 98% to 99%.
