About the results of experimental study performed on a “decarbonizer – vacuum deaerator” system

Abstract

Abstract The paper discloses the results obtained in experimental study, implemented at an operating water treatment unit of the thermal power plant. The study was carried out via using the method of a complete factorial experiment. As a result of the experiments, the dependencies between objective functions and a number of controlled parameters have been determined. Regression equations have been derived and cross-sections of the response surfaces have been constructed in a natural scale, that adequately describe the processes of corrosive gases desorption within the “decarbonizer - vacuum deaeratof’ system. The data obtained allows one to assess the minimal technologically acceptable level, when it is possible to lower the temperature of the treated water and, consequently, to reduce the energy costs for its heating, and to specify the conditions when the reduction of the energy costs for supplying air to decarbonizer is possible.
