The current status of circulating fluidized bed (CFB) technology employed at foreign TPPs is briefly analyzed. It is demonstrated that CFB technology is entirely suitable for the building of 225- and 330-MW units with enhanced steam parameters, and also for replacement of boilers at TPP with cross links. Placement of prospective standards into effect for harmful effluents, and diversification of fuel supply are important advantages of this technology. It is shown that CFB boilers based on unified subassemblies could be built at least for groupings of fuels. Results of mathematical modeling of processes in furnaces of CFB boilers, which are in satisfactory agreement with data obtained from simplified engineering methods, are presented. Further improvement of the mathematical model, and a series of analyses of the furnace circuit in the nonsteady statement with a supercomputer are being traced. © 2011 Springer Science + Business Media, Inc.
