AB - Last ten years the attention of the research and development efforts in developed countries has been moved from bubbling FBC to circulating FBC. Low prices of the liquid fuel and gas and more stringent emission standards make burning of coal in bubbling FBC boilers and furnaces non competitive compared to the boilers burning liquid fuels or natural gas in the range of unit power from small to medium. As the only market for FBC boilers rests the electric power generation in large utility boilers. 
The situation in undeveloped countries is different. There is still need for use of the local fuels (coal, biomass, wastes) in order to substitute expensive imported liquid fuels or natural gas, especially in the field of energy generation in industry and district heating. At the same time, distributive energy generation become more and more interesting, and is mainly based on local and low quality fuels. Unit sizes suitable for distributive energy generation range from 0.5 MWth up to 500 MWth. BFBC boilers and furnaces are economically acceptable in this power
range. In BFBC boilers and furnaces is possible to burn, at the same time or alternatively, fuels of different origin and quality, biomass of different type and industrial and municipal wastes. In addition, boiler manufacturers in undeveloped countries can produce BFBC boilers and furnaces, independently or based on cooperation with the world known licensers of the FBC technology. According to the author's opinion, BFBC technology is the best solution for distributive energy generation.
