Study on Layout of 660 MW Ultra-Supercritical Circulating Fluidized Bed Unit Main Plant
As an advanced low-carbon power generation technology,the ultra supercritical circulating fluidized bed unit has broad market prospects.This paper combines the actual engineering of a 660 MW ultra supercritical circulating fluidized bed unit to study the layout of the main plant.Through technical comparison between Scheme Ⅰ(three row front coal bunker)and SchemeⅡ(four row front coal bunker),it is recommended to use Scheme I as the layout plan for the main factory building.The recommended layout plan for the main plant adopts a combined layout of deaeration room and coal bunker room,which reduces the occupied area and volume of the main plant,reduces the investment in the four major pipelines,and is economically feasible in engineering design,providing reference for the layout of the main plant of large capacity ultra supercritical circulating fluidized bed units.
