摘　　要：启动循环泵(BCP)作为超超临界锅炉启动系统核心设备,在机组启停效率、调节特性及低负荷安全性上具有明显作用,可以较好地适应电网深度调峰需求.通过对国产与进口BCP在价格、交货及质保期方面的对比,得出国产BCP具有较明显优势.随着国家对火力发电机组调峰需求的提高及发电设备国产化的推进,市场对国产BCP的需求日益凸显.目前,国产BCP在应用业绩上与进口产品还存在差距,但随着市场需求的扩大,其具有一定的发展前景.Boiler water circulating pump(BCP),as the core equipment of the start-up system of ultra-supercritical boiler,plays an obvious role in the unit start-stop efficiency,regulation characteristics and low-load safety,and can better adapt to the needs of deep peak regulation of power grid.Through the comparison of domestic and imported BCP in terms of price,delivery and quality guarantee period,domestic BCP has obvious advantages.With the increase of domestic demand for peak regulation of thermal generating units and the promotion of power generation equipment localization,the market demand for domestic BCP has become increasingly prominent.At present,there is still a gap between domestic BCP and imported products in application performance,but with the expansion of market demand,it has a certain development prospect.
