Cogeneration of power and heat in Hungary

Abstract

For the first time in Hungary, a geothermal ORC power plant is being built, and will have the capacity to generate 2.2-2.5 MW of electricity. It is located in Tura, 30 km east of Budapest. After a long design and optimisation procedure, some questions are still unanswered. This paper reports answer to some of these, like how much heat the power plant can provide for the greenhouse designed near to the power plant, and how much water is needed to replace the evaporated water in the evaporative condenser, as well as how the ambient temperature will influence the screw expanders power output through the condenser. To evaluate these tasks, a Scilab code was written. The main parameters were provided by Mannvit Consulting Engineers.
