摘要：In coal-fired power stations, about 20% of the ash produced in the boilers is deposited on the boilerwalls, economizers, air-heaters and super-heater tubes. This deposited ash is subsequently discharged as slag andclinker during the soot-blowing process. The rest of the ash is entrained in the stream of flue gas leaving the boiler.These ash particles collide with the boiler steel components and cause extensive surface erosion.Using software (CFD) analysis of boiler tube considering materiel of tube and velocity abrasive ashparticle is done in main superheated tube. For the analysis differentiate between various modes of wear, and tounderstand which mode is the primary driver for tube failures,A model of tube was developed and effect of erosion is investigated. An analysis of tube with differenttype velocity of fly ash, I have been carried out to reduce the erosive effect on water tube boiler with the help of CFDsoftware we analyze and optimize the effect of erosion Using data analyze by CFD , mass removing rate to differentvelocity of fly ash
