Mitsubishi Latest Coal Fired USC Boiler Technology (CFE Pacifico 700MW)
Mitsubishi Heavy Industries,Ltd.(MHI) has successfully completed commissioning work for CFE (Comision Federal de Electricidad) Pacifico 700 MW coal-fired unit in March 2010 which is the first supercritical unit in Latin America.This supercritical boiler was designed with state of the art technologies such as low NOx burners,high fineness pulverizers,advanced vertical furnace wall technology and so on.Especially the advanced vertical furnace wall technology with some improvements is a key technology to realize swift load changes such as 5％ load per minute ramping rate with assuring dynamic characteristics.Recently the requirement of the high efficiency and the swift load changes for the power boilers has been increased so that even a coal-fired unit needs flexible operation characteristics for balancing variety of power sources.One of the challenges for the swift load change is to keep the furnace wall metal temperature low during the load change,which the advanced vertical furnace wall could realize.The report describes the features of the unit and commissioning result including load swing test results in details.
