【 摘 要 】

A new technology for low-temperature degassing of the make-up water was developed using natural gas as a desorbing agent. The calculation of the energy efficiency of the developed technology for a typical power unit of the heat power plants (HPPs) is performed. Theoretically necessary and actual specific costs of natural gas are estimated to ensure the normative quality of the deaeration. The calculation of the hydrodynamic characteristics of the atmospheric deaerator at work on natural gas is presented.
