JG-55/3.82-M Boiler Improvement

为了提高节能降耗水平,节约能源,降低成本,对动力厂第一锅炉房四台55t/h锅炉进行技术改造。将原煤粉-煤气混烧锅炉改为纯烧高、焦炉煤气的燃气锅炉,同时,对原煤粉燃烧器及除尘系统进行改造,将下层一次风进口改为小型煤气燃烧器。通过技术改造每年可增加蒸汽产量约28800t,每年可节约动力煤4900t,经济效果显著。

In order to increase the level of energy saving and consumption reducing,decrease costs,the four 55 t/h boilers atthe first boiler room,Power Plant,are modified.The pulverized coal -gas fired boiler is changed to a BF gas -coke oven gas fired boiler.Meanwhile,the original pulverized coal burner and dedusting system are modified and the tuyeres at the next layer are modified into smaller gas burners.After technical improve-ment,the steam generation is increased by about 28,800 t an-nually and coal used for power is saved by 4,900 t per year,re-sulting in prominent economic benefits.
