Применение регулирующей ступени на базе профилей ЛПИ в паротурбинной установке мощностью 800 МВт на базе К-800-240-5

Abstract

Данная работа посвящена расчётному исследованию возможности применения ступени конструкции ЛПИ в мощной паровой турбине на базе К-800-240-5. Задачи, которые решались в ходе исследования: 1. Расчет проточной части по предварительно заданному количеству ступеней; 2. Проектировочный расчет традиционной регулирующей ступени в программе OPTI; 3. Расчет проточной части ЦВД в программе OPTI; 4. Предварительный расчет в программе Turbo; 5. Теплотехнический расчет регулирующей ступени ЛПИ с помощью программы ONE. В работе представлено расчетное исследование регулирующей ступени паровой турбины на базе К-800-240-5. Предложено и обоснована возможность использования конструкции регулирующей ступени на базе профилей ЛПИ в мощной паровой турбине. В результате была произведены и проанализированы различные расчеты регулирующей ступени конструкции ЛПИ. Доказана возможность срабатывания большого перепада энтальпий в новой регулирующей ступени с одновременным повышением КПД и мощности ступени.

This work is devoted to a computational study of the application feasibility of the LPI design control stage in a high-power steam turbine based on K-800-240-5. The research goals are: 1. Calculation of the flow channel according to a predetermined number of steps; 2. Design calculation of the traditional control stage using the OPTI program; 3. Calculation of the flow channel of the HPC in the OPTI program; 4. Preliminary design in the Turbo program; 5. Thermo-technical calculation of the control stage with the LPI design using the ONE program. The paper presents a computational study of the control stage of a steam turbine based on K-800-240-5. The possibility of using the design of the control stage based on the LPI profiles in a high-power steam turbine is proposed and justified. As a result, various calculations of the control stage with the LPI design were made and analyzed. The possibility of operation with a large enthalpy drop in a new control stage with a simultaneous increase in efficiency and power of the stage is proved.
