The use of vacuum deaerators instead of atmospheric deaerators in the degassing of feed and makeup water makes it possible to increase significantly the economy of thermal power plants. The main factors determining the advantage of DCV with respect to DCA in terms of economy are: in the degassing of makeup water, the application of steam of low potential bleeding or spent turbine steam for the heat carrier heating before DCV; the elimination of losses in the heating steam condensate at the expense of application as heating agent of overheated makeup or network water; and in the degassing of feed water, a drop in the steam pressure of thermal bleeding of turbines, in which DCV is included to a level to be determined by the operation thermal network temperature diagram; and the application of low potential nonadjustable turbine bleeding for deaerated water regenerative heating.
