10t/h燃煤蒸汽锅炉改造为燃气锅炉方案

燃煤锅炉

  在实际使用运行中,热效率低,能源浪费大,排尘浓度大,煤的含硫量高,对大气污染严重。尤其是近年来,能源供需和环境污染的矛盾日益突出。而燃气锅炉的热效率高,对大气污染又低,有很好的环保性能。发达国家的燃气锅炉占有相当大的比重,俄罗斯占60%,美国占98%,日本占99%,发展燃气锅炉是大势所趋。因此,我国越来越多的大中城市制定了相应的强制性法规,限制燃煤锅炉的使用,例如北京、上海、西安等地不再批准建设新的燃煤锅炉房,原有的锅炉房一律改造为燃气锅炉。根据新的环保法,对产生大气污染的设备要实行监管,严格限定污染物的排放量,实施“碧水蓝天工程”,推荐使用清洁燃料或天然气,各级政府会采取相应措施,推行燃煤全面及燃气化改造。天然气是目前世界上一种最清洁的燃料,它燃烧充分,产生的灰份、含硫量和含氮量比燃煤低的多。同时,气体燃料通过管道输送,可极大的减小劳动强度,改善劳动条件,降低运行成本。国家“西气东输”、“忠气进汉”等工程的实施,使XX市年底即可用上天然气,为锅炉的煤改气提供了优质、充足、廉价的气源。

  XX啤酒原有10t/h燃煤蒸汽锅炉一台,该锅炉为上海四方锅炉厂生产,型号SHL-1.25-AⅡ型,2000年生产,2003年投入使用。锅炉炉体受压元件基本完好,有继续使用价值;锅炉的给水系统和送、引风系统基本完好,非常适宜改造为燃气锅炉。
