Abstract

BUŽEK, M. Conceptual Design of Cogeneration Units to Supplement current Heat Source: Master Thesis. Ostrava: VŠB – Technical University of Ostrava, Faculty of Mechanical Engineering, Department of Power Engineering, 2019, 58 p. Thesis head: doc. Ing. Míka, J. CSc. The diploma thesis named above, deals with the design of a cogeneration unit for heat source replenishment. The building for which the design is implemented is a boiler room with hot water boilers 130/90 ° C. The theoretical part of the thesis describes electrical and thermal energy and their combined production, description of cogeneration units and their distribution according to drive and use. In the practical part of the thesis, was designed a cogeneration unit with the output corresponding to the replaced boiler. Furthermore, was calculated the heat balance of the internal combustion engine for the selected unit. The thesis also includes the design of the storage tank and the design of the flue gas-water heat exchanger. At the end of the thesis is made an economic evaluation and the annex contains a drawing of a tube heat exchanger combustion gases – watter.
