Abstract
According to the investment programmes of Russian electricity generating companies increased attention is paid to reconstruction and building new coal TPP. The typical projects are 225, 330 and 600 MW blocks for combustion of different domestic coals. VTI had made technical and economical comparison of CFB and PC boilers for existing and perspective (European) standards of particles, NOx and SOx emissions, according to the data of the prehminary designs and investments in new power plants of 225 and 330 MW. As the basis for technical and economical evaluations was used comparison data of metal-capacity of PC and boilers, emissions-control systems and material-handling systems, with paying attention to the exact suggestions of the boiler producers. The results of the comparisons (capital costs and O&M costs) are discussed in the paper. The most perspective fuels for combustion in CFB boilers are: anthracite culm, coals of the Pechora area, lean coals of Kuznetsk, brown coals of near Moscow, brown coals of Urals and Far East, and also the wastes of coal preparations, peat, shells and biomass. A good composition could be made from Kuznetsk coals and coals of Pechora area. Brown coals are combusted very good in suitable conditions for firing biomass and peat. Also allowed co-combustion with the wastes of coal preparations for the low reactivity fuels such as anthracite culm and lean coals. The diversification of the fuel supply is an essential advantage of CFB boilers. The CFB boiler installations are rather new for the conditions of Russian Federation. For decreasing the technical risks, first installations should be supplied by engineering or license of leading foreign companies with rather big part of their participation. One of important tasks is development of the typical projects, which would allow decreasing not only capital costs, but also decrease time of project realization. The project of the new Block #9 330MW with OTU boiler of Novocherkassk TPP is the determining for the wide use of CFB technology in Russia. The block is designed for combustion of the Anthracite culm, Kuznetsk lean coals and coal slurry and should be established in 2011 year.
