Pre-feasibility study for a
construction of a new unit in Warsaw. The analyses covered multiple
alternatives of power units from 200 to 700 MWe, sub- and
supercritical, of varied heal output. Analyses were made for two
possible locations, at Siekierki CHP Plant and at Kawęczyn Heat Plant.

present and future environmental requirements. The analyses took into
account a number of parameters and conditions influencing the optimal
selection of recommended alternative, such as combustion technologies,
steam parameters, thermal cycle of the plant, concept of district
heating part, various cooling solutions involving an open cooling
system as well as dry and wet fan cooling towers, plant preparation for
the future requirements for CO2 reduction. Thermal cycles of the
analysed alternatives were modelled and analysed for a number of loads.
As a result of the analyses, supercritical coal-fired units were
recommended as optimum solution, for the location of Siekierki - 450
MWe net, for the location of Kawęczyn – 650 MWe. |
