火电厂化学系统运行优化节能措施分析及应用

Analysis and Application of Energy Saving Measures for Optimization of Chemical System Operation in Thermal Power Plants

燃煤价格不断升高,发电企业的发电成本水涨船高。通过下调给水pH值、提高精处理树脂再生酸碱浓度、延长进酸碱时间,以延长精处理树脂运行周期,减少再生次数,节约化学药品及除盐水用量。在电力市场现货交易背景下,利用峰谷电差价,利用冷却塔、工业水池、除盐水箱、凝输水箱等设备进行蓄水蓄能,达到节能降耗、挖潜增效目的。

The price of coal continues to rise,and the cost of electricity generation for power generation companies has skyrocketed.By lowering the pH value of the feedwater,increasing the concentration of acid and alkali in the regeneration of the fine treatment resin,and prolonging the acid and alkali inlet time,the operating cycle of the fine treatment resin can be extended,the number of regenerations can be reduced,and the amount of chemicals and desalinated water can be saved.In the context of spot trading in the electricity market,utilizing the price difference between peak and valley electricity,and utilizing equipment such as cooling towers,industrial water tanks,desalination water tanks,and condensate water tanks for water storage and energy storage,the goal of energy saving,consumption reduction,and potential efficiency improvement can be achieved.
