Study on the Optimal Back-Pressure of Direct Air-Cooled Condenser in Theory

In order to improve the system running economics of the direct air-cooled unit, based on the thermodynamic model of the air-cooled system, through considering the steam turbine power and the consumption power of fan, this article has researched the optimal back-pressure of the unit in theory under the running conditions, and given the basic law about the optimal back-pressure affected by the corresponding main factors. Thus, the results of studying will provide helpful guidance for the cold-end optimization and economical running of the direct air-cooled thermal power plants.
