Abstract

Abstract:

The transformation of desulfurization equipment of thermal power unit is becoming more and more urgent for the problem of substandard emission concentration from the most power plants. The feasible transformation scheme of 2×600MW supercritical units’ desulphurization device of a coalfired power plant is analyzed and studied. Based on desulfurization efficiency experiment, two schemes which are twin tower double circulation and single tower are proposed. Technological and economic analyze of these two schemes are made and compared. Meanwhile, by comprehensively considering the influence factors, such as technology risk, transforming difficulty, transformation period, site area and project investment, twin tower modification scheme is identified as a more suitable scheme. It provided reference for the transformation of the denitrification device for domestic thermal power unit in the future.
