Abstract The transformation run of big capacity adjusting peak set is the important trend of combusting coal plant in recent years.The merit and feasibility of optimium run to boiler set in combusting coal plant,and the influence of transformation run to boiler set and feeding water pump were analyzed particularly,and the comparison was done between them and traditional steady pressure throttle preparing stream mode;adjusting pressure range and optimized running mode was deduced for feeding water pump transformation running mode applied in combusting coal plant adjusting peak set.The mode takes into account of the feed water criterion,the efficiency of pump and the disposition of itself all-round,the physics signification of that accords with the practice,and it has important meaning to the saving energy and reducing consumption of adjusting peak set.It is testified that the efficiency of boiler could be increased 3%,and electricity consumption of pump could be saved 30%~60% with the use of transformation run.
