| Abstract: | The main features of the thermal power unit steam turbine, condenser, circulating pump and pipe network systems and mutual restriction have been analyzed combining theoretical analysis with experimental analysis. Through optimization of the circulating water system and transformation of circulating pump in 1 036 MW units, several combination programs for optimized operation have been made and optimized operation mode of circulating water system has been achieved. After comparing coal and electricity price, a great amount of energy saving and consumption reduction has been achieved at the cold end of million units; the best energy-saving control of the variable flow has also been obtained. |
