Application of the method of discrete-pulse energy input for water degassing in municipal and industrial boilers
The main advantages and disadvantages of chemical and physical degassing of liquids are considered. It was found that hydrodynamic cavitation should be considered as an important alternative to acoustic cavitation, both in terms of performance and, above all, in terms of energy saving.

The main advantages and disadvantages of chemical and physical degassing of liquids are considered. It was found that hydrodynamic cavitation should be considered as an important alternative to acoustic cavitation, both in terms of performance and, above all, in terms of energy saving. The processing of two liquids - acidic condensate and model solution (solution of carbon dioxide in distilled water) was performed. The dynamics of changes in the content of dissolved carbonic acid depending on the duration of hydrodynamic treatment in order to determine the optimal processing duration to achieve the required degree of degassing are studied. Liquids were treated on a l laboratory-scale plant developed as part of the implementation of the method of discrete-pulse energy input into heterogeneous media, which creates conditions for intensive growth of vapor bubbles and their removal. The pH values were obtained and the concentrations of carbonic acid in the acidic condensate and the model solution were calculated from the duration of their processing. It was found that the main change in the pH of the model solution and acidic condensate occurs approximately during the first two minutes of processing. The increase in pH and, consequently, the decrease in the dissolved carbonic acid content of both liquids for several days are explained by the relaxation process during which carbon dioxide microbubbles emerge from the liquid, which did not have time to leave the liquid.
