The efficient coal alternative. Petroleum coke-fired CFB boilers in Europe Damian Góral, Anna Wylenżek Foster Wheeler Energia Polska Poland

Abstract: Petcoke is not just a refinery’s by-product any more, but a real alternative costeffective fuel that can be successfully fired in CFB boilers either alone or in blends with coal. With its specific ash content, which is typically lower than 1 percent and very high sulfur, petcoke is an effective source of energy increasing plant economy. Foster Wheeler CFB technology allows efficient combustion of petroleum coke. Numerous references are located mostly in United States or China reaching utility capacities of 300 MWe with the first commercial application dating back to 1984. Now in Europe Foster Wheeler delivered efficient and fuel-flexible petcoke-fired boilers to Bulgaria and Romania allowing customers to use not only standard coals, but also alternative fuels of different origin and properties. In spite of high sulfur content of the fuel reaching up to 8 percent the environmental performance of the units is excellent allowing to achieve low emission limits without external DeSOx and DeNOx installations. To meet the customer’s specific requirements the design allowed the usage of the local limestone or co-firing of heavy oil together with petcoke. Studying the potential of alternative fuels such as petcoke CFB technology appears to be the perfect solution since in many cases fuel flexibility may be a decisive factor in a plant’s economy and feasibility of new projects. 1. Fuel Origin and Characteristics Petroleum coke (Petcoke) is a carbonaceous solid derived from oil refinery coker units or other cracking...
