Cost and Benefit Analysis of Desulfurization System in Power Plant
Abstract: The economy of
desulfurization system is of great significance for operation of
desulfurization system and improving the environment quality in power plant.
Based on the desulfurization power price policy, this paper analyzes the cost
and benefit structure of the wet flue gas desulfurization system in Chinese
power plant; that puts forward the calculation methods of total cost present
value, total benefits present value and net present value during the life
period of desulphurization system. Moreover using Cost-benefit sensitivity
analysis to find out that there is sensitivity relationship between power
generation hour and desulphurizer price. By applies these methods, the result
shows that the economy of desulfurization system is better under the current designed
scheme. But with the reduced power hour and risen price of limestone, the
current desulfurization system power price policy of China cannot compensate
the running cost of the desulfurization system in power plant rationally, and
leads to lower economy of desulfurization system.
