The repowering of JEA’s Northside plant promises to become a major milestone in the development of circulating fluidised bed (CFB) boiler technology. The project should provide a benchmark against which to assess the application of CFB technology at the 300 MWe scale, including economies of scale, maintainability, availability, and reliability.
Fluidized bed combustion (FBC) is a combustion technology used to burn solid fuels.. In its most basic form, fuel particles are suspended in a hot, bubbling fluidity bed of ash and other particulate materials (sand, limestone etc.) through which jets of air are blown …

CFB boilers can therefore be designed to take essentially any solid fuel, hence another major impetus for their development has been their use in firing biomass in the pulp and paper industries of Sweden and Finland. Although CFB boilers are generally designed for a specific fuel, the tolerance of a unit to
is applied to a CFBC boiler, the combustion temperature can be controlled by recycling a portion of the cooled solids to the furnace through a fluidised-bed heat exchanger, therefore minimal flue gas recirculation is required. This characteristic allows the oxy-CFB boiler to be made smaller and less expensive in a new unit application.
This will also consist of 2x300 MWe CFB units, burning bituminous coal. An order for the third co-production plant, from Shanghai Boiler, is expected in the next few months. In addition there are many other 300 MWe CFBs projects in China planned for implementation on the co-production or licence basis, with substantial opportunities for further
Retrofitting of Provence 4 with a 250 MWe CFB boiler was an important step in CFB development. In light of the results obtained from two large French units--Emile Huchet 4 (125 MWe) and Provence 4 (250 MWe)--this paper focuses on the main technical points which are currently being studied in relation to the basic design of a 600 MWe CFB boiler
