Utilization of petroleum coke and petroleum coke/coal blends as a means of steam raising
暂无分享,去创建一个
A glut of petroleum coke has made it an attractive source of cheap Btu's, either as the primary fuel or as a coal/coke blend for generating steam. Petroleum coke, unlike coal, is low in volatiles and contains substantial concentrations of vanadium, nickel, and sulfur, which can be sources of combustion and fireside fouling or corrosion problems if not properly handled. This paper discusses the combustion characteristics of the various types of petroleum cokes and blends used for steam raising and the fireside behavior of the mineral matter they contain. Field experience and laboratory trials indicate petroleum cokes containing vanadium as high as 10000 ppm can be fired.
