查询词典 fossil fuel

So the proposed method in this dissertation not only meet the requirements for fossil-fuel unit set in GB/T 12145-1999, but also can effectively restrain condensate and feed water system corrosion. Thereby the proposed method can reduce the loss by corrosion's leading accident, lower Fe content in boiler feed water, slow the boiler's scaling speed, delay boiler's chemical cleaning interval, effectively enhance unit's reliability, usability and using life and solve the problem of poisonous chemical deoxidant. So the proposed method can economize substantial expense for power plant.

所以，本文所提出的汽包炉有限氧化性水化学工况不但能满足GB/T12145-1999中对火力发电机组及蒸汽动力设备的要求，而且可有效抑制凝结水和给水系统的腐蚀，减少因这些部位腐蚀损坏而引发的事故停机损失，降低锅炉给水中的金属含量，减轻炉内的结垢速度，延长锅炉的酸洗间隔，有效提高机组的可靠性、可用率和使用寿命，同时也解决了有毒化学除氧剂的使用问题，为电厂节省大笔运行费用。
