Goncharenko A. Improvement of methods of calculation, models and constructions of superficial condensation vehicles of caldron options of small and middle power

Research Object: technological processes which flow in the systems of deep utilization of warmth of exhaust gases of caldrons. Research purpose: improvement of methods of calculation, models and constructions of superficial condensation heat-exchange vehicles, which are used in the systems of deep utilization of warmth of exhaust gases for the increase of economy of steam and water heat caldrons. Research methods: theoretical positions of dissertation are based on fundamental bases of theory of heat exchange and mass-transfer and hydrodynamics. For the analysis of processes of heat exchange and mass-transfer and condensations of vapor the methods of mathematical design are used. Theoretical and practical results: the methods of calculations of the closed technical system of " caldron - heat utilizer ", and also complex of the computer programs developed on their basis, can be used for developments of effective technologies of deep utilization of warmth of get-away gases of caldrons. Novelty: the mathematical model of the closed technical system of " caldron - heat utilizer " is first developed, which is based on the improved methods of calculation heat exchange - and mass-transfer in the conditions of vapor from gases; the mathematical model of condensation air heater is first developed with intermediate spherical; the method of thermal calculation of condensation heat-exchange vehicle of superficial type is improved.
