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。
