Facing the situtation in shortage of energy and water resources

as well as the deterioration of environment being severe with each passing day in our country

one of the main measure for energy-saving is optimization of system design in designing thermal power plants

utilizing reasonably the residual heat of flue gas in thermal power plants

enhancing the efficiency of units

and decreasing the coal consumption.The way of utilizing residual heat of flue gas in thermal power plants has been analysis

the system of utilizing residual heat from flue gas to heat the condensate being emphasitically studied.Study shows that the installing of residual heat utilization system of flue gas can enhance thermal efficiency of the whole plant

decreasing the coal consumption

increasing the generated energy

having certain economic and social benefits.
