废热锅炉烟管严重漏水故障的原因分析

废热锅炉是利用船舶内燃机排出的废气作为热源的蒸汽锅炉.废热锅炉是营运船舶必不可少的设备,它产生的蒸汽供给燃油、机油、甲板水和口用水的加热和消防、取暖和厨房等地方的用汽.如果废热锅炉出现故障,轻则严重蒸汽不足;重则废热锅炉不能使用,直接影响到主机的运转,继而影响船期,甚至船舶安全.导致废热锅炉故障的原因有许多,如水质的管...

Shallow Analysis about the Serious Leaking Breakdown in Fire-tubes of Waste-heat Boiler

Waste-heat boiler is often used to recover some of the heat carried in the exhaust gases from the main engines in motor ships.Waste-heat boiler is the essential equipment in the operation ships.The vapour supply the fuel oil,lube oil,the deck and daily water to heat and fight fire,supply air condition to keep warm and kitchen to cook,etc.If exhaust gas boiler appear to breakdown,the light,there would a serious steam shortage;then heavy it can＇t be used.So,that would affect directly the operation of main engine,affect the sailing schedule subsequently,even affect ship safety.Many reasones may be cause exhaust gas boiler to breakdown,such as the feed water and water level of management,the smoke side of management,etc.Through analysing a typical breakdown in this text,explore to the reason of waste-heat boiler breakdown about disappropriate soot-blow,and try to look for some good methodes to blow away soot,expect to provide a certain reference for waste-heat boile governor.
