Газотурбинная установка мощностью 12 МВт

Abstract

В данной работе проведен расчет газотурбинной установки мощностью 12 МВт, выполненной на базе двигателя НК-12 СТ. Для достижения поставленных задач осуществлялись следующие расчеты и исследования: 1. Расчет тепловой схемы посредством программы A2GTP. 2. Расчет проточной части турбины компрессора (ТК) и силовой турбины (СТ). 3. Расчет закрутки потока последней ступени. 4. Прочностные расчеты последней ступени турбины. 5. Кратко изложены общие понятия об основных элементах и узлах прототипа НК-12 СТ. 6. Анализ применения лопаток с криволинейной осью, а также их сравнение с радиальными лопатками для последней ступени силовой турбины. В результате теплового расчета были получены оптимальные параметры для турбины и компрессора. Итогом газодинамического расчета являются параметры, служащие для построения 3D модели лопатки последней ступени турбины. Результатом прочностного анализа является определение коэффициента запаса прочности лопатки и диска, а также частотный анализ ротора и лопатки последней ступени турбины. В специальной части проведен анализ лопаток с разными видами тангенциального наклона, их влияние на поток и на КПД газотурбинной установки, также установлены взаимосвязи между применением лопаток с криволинейной осью и эффективностью ступеней турбины.

This paper, the calculation of a gas turbine unit with a capacity of 12 MW is carried out. The GTU is based on the NK-12 ST engine. To achieve these goals, the following calculations and studies were carried out: 1. Calculation of the thermal circuit using the a2gtp program. 2. Calculation of the flow part of the compressor turbine (TC) and power turbine (ST). 3. Calculation of the flow twist in the last stage. 4. Strength calculations of the last stage of the turbine. 5. Briefly described the general concepts of the main elements and nodes of the prototype NK-12 ST. 6. Analysis of the use of blades with a curved axis and their comparison with radial blades for the last stage of a power turbine. As a result of thermal calculation, optimal parameters for the turbine and compressor were obtained. The result of gas-dynamic calculation is the parameters used to build a 3D model of the blade of the last stage of the turbine. The result of the strength analysis is the determination of the safety factor of the blade and disk, as well as the frequency analysis of the rotor and blade of the last stage of the turbine. In the special part, the analysis of blades with different types of tangential inclination, their influence on the flow and on the efficiency of the gas turbine unit, as well as the relationship between the use of blades with tangential end wall contouring and the efficiency of the turbine stages is established.
