江苏徐矿综合利用发电有限公司实施供热改造,替代周边供热区域内3家热电厂以及69台小锅炉[1],承担起全区工业生产和居民采暖所需供热.随着华东地区新能源发电和区外来电份额逐年增加,电网对传统火电机组调峰能力和性能有了更高要求.供热系统出力与汽轮机负荷呈正比,冬季大流量供热期间,需要维持较高的电负荷,AGC调节能力不足,面临着流化床锅炉长期满负荷运行带来的返料器料腿烧红、加剧受热面磨损等问题,进行热电解耦提升机组灵活性势在必行.
Study on flexibility of thermal electrolytic coupling to improve the unit
Jiangsu Xukuang Comprehensive Utilization Power Generation Co.,Ltd.implemented heating transformation to replace three thermal power plants and and 69 small boilers in the surrounding heating area,undertaking the heating needs for industrial production and residential heating in the entire area.With the increase in the share of new energy power generation and foreign electricity in East China year by year,the power grid has higher requirements for the peak regulation capacity and performance of traditional thermal power units.Heating system output is proportional to the load of the steam turbine,during the winter large-flow heating,it is necessary to main-tain a high electrical load,AGC regulation ability is insufficient,facing the problems such as burning red legs of the feeder and intensif-ying wear on the heating surface caused by long-term full load operation of fluidized bed boilers,it is imperative to carry out thermal e-lectrolytic coupling to improve the flexibility of the unit.
