Газотурбинная установка мощностью 170 МВт для работы в комбинированном цикле

Abstract

Целью данной работы является проектирование газотурбинной установки мощностью 170 МВт на основе прототипа ГТУ V94.2. Задачи, которые были решены в ходе работы: 1. Расчет тепловой схемы, на основании результатов которого выбирается степень повышения давления в компрессоре и температура на входе в турбину; 2. Газодинамический расчет осевого компрессора; 3. Расчет камеры сгорания с получением ее геометрических размеров и экологических характеристик; 4. Газодинамический расчет турбины; 5. Расчет закрутки потока для последней ступени турбины 6. Построение трехмерной модели рабочей лопатки и диска последней ступени турбины; 7. Расчет на прочность рабочего колеса последней ступени турбины; 8. Расчет на вибронадежность вала ротора и рабочего колеса последней ступени турбины; 9. Описание конструкции газотурбинной установки; 10. Определение КПД блока «последняя ступень – дифффузор»; 11. Модернизация периферийного обвода кольцевого диффузора в соответствии с формой профиля силовых стоек с целью повышения эффективности блока «последняя ступень – диффузор».

The purpose of this work is to design a gas turbine plant with a capacity of 170 MW based on the V94.2 prototype. Tasks that were solved during the work: 1. Calculation of the thermal scheme, based on the results of which the degree of pressure increase in the compressor and the temperature at the turbine inlet are selected; 2. Gas-dynamic calculation of axial compressors; 3. Calculation of the combustion chamber with obtaining its geometric dimensions and environmental characteristics; 4. Gas-dynamic calculation of a turbine; 5. Calculation of the flow twist for the last stage of the turbine; 6. Construction of a three-dimensional model of a working blade and disk of the last stage of turbine; 7. Strength calculation of turbine elements; 8. Calculation of vibration reliability of the rotor shaft and impeller of the last stage of the turbine; 9. Description of the gas turbine plant design; 10. Determination of the efficiency of the "last stage – diffuser" unit; 11. Modernization of the peripheral circumference of the annular diffuser in accordance with the shape of the profile of the power racks in order to increase the efficiency of the "last stage – diffuser" unit.
