Gandga A. Improving the efficiency of surface heat and mass exchangers through the development of local distribution regularity of heathydraulic parameters

The subject of inquiry - the process in recuperative heat-mass exchange devices of power plants and systems in service conditions. Purpose of research - effectiveness increase of heat-mass exchange equipment. Theoretical and practical results - a more accurate determination of heat-hydraulic parameters of heat exchangers will reduce their mass and size of costs and energy on their functioning. Ways to maximize heat and economic efficiency and heat exchangers taking into account limitations that ensure operational reliability are required. Created dependence, methods, algorithms and their software-based computer systems used for a wide range of heat exchangers used in industry, energy and communal-general sector. Novelty - developed and refined a system of specified dependencies for analyze the and effectiveness increase of surface heat-mass exchangers by considering the distribution of local heat-hydraulic parameters that depend on the peculiarities of heat flow, surface composition and operating factors. Extent of heading - Improved dependencies and techniques used for optimal load modes of heat exchange equipment in the most energy-intensive industries PC "MK AZOVSTAL", Mariupol. Methods for determining the effectiveness of heat exchangers subject to conditions and technological factors was used for analysis, evaluation and improvement of energy performance of the KKE "Donetskgorteploseti", KE "Kryvorizhteplomerezha", Lugansk SKE "Teplokumunenerho", KE "Kharkiv Heating Networks" and others. Industry of application - industrial heat-power engineering.
