Abstract:Kogeneracija je sočasno pridobivanje toplotne in električne ali mehanske energije iz enega vira goriva, pri katerem je izkoristek goriva 70–90 %. Primarni namen kogeneracije je pridobivanje električne ali mehanske energije, sekundarni pa izkoristek odpadne toplote. Glavni viri odpadne toplote v motorju z notranjim zgorevanjem so izpušni plini in odvedena toplota z motornim oljem ter hladilom. V diplomskem delu smo se osredotočili na agregat z rekuperacijo odvečne toplote za ogrevanje stanovanjskih enot. Poudarek je na prenosniku toplote izpušnih plinov ter preučevanje vpliva goriva na velikost toplotnega prenosnika izpušnih plinov. V ta namen je bilo narejenih s pomočjo programskega paketa AVL BOOST več modelov motorja z notranjim zgorevanjem, pri katerih so se uporabila različna goriva. Iz BOOST-ovih modelov se je odčital toplotni tok izpušnih plinov ter se jih uporabil v preračunu potrebne površine toplotnega prenosnika za posamezno gorivo.
Keywords:kogeneracija, prenos toplote v motorjih z notranjim zgorevanjem, prenosniki toplote, BOOST.

Title:Description of cogeneration with transport phenomena
Abstract:Cogeneration is the simultaneous production of thermal and electrical or mechanical energy out of the same fuel source, where the fuel efficiency is between 70 and 90%. The primary purpose of cogeneration is the production of electrical or mechanical energy and the secondary purpose is recovery of the waste heat. Most of the waste heat in an internal combustion engine is contained in the exhaust gases and in the coolant and lubricant. In the course of this work, a generator with waste heat recovery for the purpose of housing heating was studied. The focus was set on an exhaust gas heat exchanger. It was studied how the fuel type would affect the size of said heat exchanger. For this purpose, several models of an internal combustion engine were constructed in the software tool AVL BOOST where different fuel types were used. Readings of the exhaust gas heat flows were obtained and used for the calculation of the necessary heat transfer area of the heat exchanger for specific fuel types.
Keywords:cogeneration, heat transfer in internal combustion engines, heat exchangers, BOOST.
