The master's thesis consists of an introduction, 4 chapters, a conclusion and 1 application.The introduction substantiates the relevance of the chosen topic, forms a goal and sets tasks, determines the subject of research.The first chapter provides an overview and classification of AGDS, identifies the needs for heat and electricity. Requirements for new generation AGDS have been formulated.The second chapter is devoted to the analysis of thermal circuits of turboexpander units and circuits of inclusion in the reduction unit.In the third chapter, a computational study of the selected schemes is carried out using the Microsoft Excel and Refprop programs and the subsequent variational calculation of the identified optimal modes.The fourth chapter describes the design features of the main elements of the turboexpander generator.In the conclusion, the main stages of the work done are listed and conclusions are formed.Appendix 1 presents two longitudinal sectional drawings of the proposed turboexpander designs. |
