DEVELOPMENT OF THE TURBOCOMPRESSOR UNIT FLOW PART FOR A BIOFUEL POWER GENERATION PLANT

The results of the study on the development of the turbocom-pressor unit flow part for a biofuel power generating plant are presented in the paper. The relevance of this paper is linked to the global trend of transition to renewable energy and reduction of carbon emissions. Types of "green" energy sources are considered, such as the use of biofuels, which is a promising source of energy. To make the energy production process cheaper, special attention is paid to the use of uncer-tified biofuels, such as agricultural waste, with a one-year re-covery cycle. It is proposed to create a power generating plant based on a grain-drying enterprise. This plant is operat-ing on the Brayton thermodynamic cycle with energy recov-ery. For this purpose, a jet-vortex heat generator, which is already operating at one of the grain drying enterprises and has a high level of efficiency, was chosen as the basis.The object of research is the turbine and compressor, the key components of a biofuel power generation plant. Using the analytical profiling methods developed by the authors, options for the flow part of the compressor of an axial-radial (centrifugal) type and the turbine of a radial-axial type were developed. CFD calculations of three-dimensional viscous flows in the flow parts of turbine and compressor were carried out using the IPMFlow soft-ware package. The compressor has achieved an efficiency of 82%, and the power is 338 kW. The turbine has achieved an efficiency of 92.8%, and the power is 438 kW, which allows to transfer 100 kW of power to the gen-erator.The study results demonstrate the high aerodynamic perfection of the designed flow parts, ensuring a satisfactory flow pattern. The developed options serve as a foundation for creating a biofuel-based power generating plant. The findings have practical value and contribute to the advancement of "green" energy in Ukraine.
