Revamping of thermal power stations focusing on extension of service life and compliance with environmental requirements

摘要

This paper reports on some of advanced clean coal technologies supplied by the Austrian Energy and Environment GmbH (AE). A short description is given of their main advantages and possibilities to offer optimal environmental and technical solutions for removal of SO(sub x), NO(sub x), HCL, HF, fine dust, aerosols, heavy metals and noise. The following technologies are considered: (1) Revamping; (2) Flue gas desulfuration - Dry Circulating Fluid Bed Scrubbing (DCFBS); MgO-based Regenerative Process (MgO-Process); Semi Dry Flue Gas Desulphurization (Spray Absorption Technology) ; Wet Flue Gas Desulphurization (limestone slurry scrubbing - IFO process); (3) Fluidized Bed Combustion - Bubbling Bed Combustion , Fast Internally Circulating Fluidized Bed Combustion, External Circulating Fluidized Bed Combustion. AE's objective is to cooperate with local firms which will provide benefits to the local economy in the following manner: (1) Foreign currency requirements for applying the technology to domestic sources would be minimized; (2) A substantial portion of the work involved in engineering, manufacturing and installing the system could be done by local personnel.
