“…Neutralisation using mass transfer processes involves removing carbon dioxide from contact with air and is implemented in absorbent-type equipment. According to several researchers, thermal deaeration of water is and will probably be for a long time, one of the main means of ensuring the reliability of heat supply systems and their heat sources, which contributes to the effective use of fuel heat during its combustion in industrial boilers (Bukowska et al 2017, Sharapov 2008, Yefimov et al 2017, Zaporozhets & Babak 2020. For example, the solubility of carbon dioxide in water varies at different temperatures, as in the case of the decarbonisation process (Zhuk 1996, Rozenberg 1973.…”

The article's authors analysed the most perspective and widely known methods of neutralising the acidic condensate, which is a by-product of natural gas combustion. Among them, the hydrodynamic cavitation method was the most effective. In this regard, it was proposed to improve this method by using the method of discrete-pulsed energy input, which involves neutralisation due to the degassing process. Based on the mathematical model of the bubble ensemble dynamics, a numerical simulation of the formation and growth of vapour-gas bubbles in the process of cavitation boiling of condensate was carried out. Also, an analytical study of the evolution of the vapour-gas bubble population and changes in the current vapour content of the condensate during its boiling was investigated under different values of the initial size of gas micronuclei. The results of the experimental study also confirmed the effectiveness of this method and showed that almost complete removal of carbonic acid from condensate occurs during the first two minutes of processing. That is evidenced by the increased pH values of condensate, which corresponds to the range of permissible pH values of distilled water. Therefore, the carbonic acid in the condensate is absent. Using this method will significantly reduce the environmental effect and the amount of harmful emissions.

The monograph examines modern problems of increasing the efficiency and safety of the operation of thermal power equipment and ways to solve them. The available methods and systems for diagnosing complex thermal power facilities have been analysed and systematised. The features and parameters of diagnosing elements of complex thermal power facilities are presented, the general requirements for diagnostic systems are substantiated. Mathematical models of the investigated fields are developed, models and characteristics of the input signals of the measuring modules of the proposed information-measuring system of diagnostics using current and retrospective information are described. Methods of forecasting abnormal states of complex thermal power objects using machine learning algorithms with LSTM architectures have been developed. A system for monitoring and controlling the process of fuel combustion in small and medium power boilers is proposed, which is based on the use of an oxygen sensor and frequency-regulated blowing fans. A method of measuring the coefficient of excess air taking into account the current volume concentration of oxygen in the air is proposed. Modern methods and algorithms for solving linear and non-linear inverse heat conduction problems of various nature are considered. A technique for obtaining the numerical solution of the main classes of inverse problems of heat conduction has been developed, which makes it possible to reduce the total number of calculations required to find the global minimum of the quadratic functional used in the formulation of most inverse problems. For researchers, engineers, as well as teachers, graduate students and students of higher educational institutions deal with the problems of increasing the efficiency and safety of the operation of energy equipment.
