The installation of dynamic Stirling engines into the turbine sealing steam system allows the recovery of sealing steam heat and the generation of electrical energy. The Stirling engine dynamics are expressed with a built-in working gas storage tank and working gas flow control to ensure adequate power output of the Stirling engine. The working gas quantity in the engine is controlled with regard to the available turbine sealing steam heat. Via the measurement of the turbine sealing steam quantity and quality, a model of the working gas pressure conditions in the Stirling engine is designed. The engine responsiveness at various working gas quantities and types is analysedV članku bomo predstavili možnosti izrabe toplote tesnilne pare parne kondenzacijske turbine z dinamičnimi Stirling motorji. Z vgraditvijo dinamičnih Stirling motorjev v armaturo tesnilne pare turbine bomo izkoriščali toploto tesnilne pare in pridobivali električno energijo. Dinamika Stirling motorja se izraža z vgrajenim hranilnikom in regulacijo količine delovnega plina, ki poskrbi za ustrezno moč Stirling motorjev. Količina delovnega plina v motorju se uravnava glede na razpoložljivo toploto tesnilne pare turbine. S pomočjo opravljenih meritev količine in kvalitete tesnilne pare turbine, bomo izdelali model tlačnih razmer delovnega plina v Stirling motorju. Analizirali bomo odzivnost motorja pri različnih količinah in vrstah delovnih plinovTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Mariboru, Fakulteta za energetiko
