Retrofitting of TPP-9 PJSC “Mosenergo” Thermal Scheme Providing Operation of GTU, HRSG, ST as a Power Unit
TPP-9 of PJSC “Mosenergo” is equipped with an AE64.3A gas turbine (manufactured by Ansaldo Energia) delivering flue gases to a Pr-94-13.8-545 single pressure vertical heat recovery steam generator (P-111, manufactured by JSC “ZiO-Podolsk”) used for generating superheated steam as well as providing heat for district heating. The generated steam enters the TPP-9 common steam header with the designed pressure of 13.8 MPa and is further used for driving steam turbines. The common steam header is also fed by conventional steam boilers located at TPP-9. Under the current scheme, the gas turbine unit (GTU) and HRSG operation is only possible in conjunction with conventional steam boilers and, therefore, separate operation of GTU, HRSG with any of steam turbines as a power unit is impossible. The requirement for joint operation of GTU, HRSG, and conventional boilers imposes significant restrictions on operating equipment as well as the load range of TPP-9 and causes low GTU, HRSG annual operating time primarily occurring during the fall-winter period. The latter is further worsened by the fact that GTU, HRSG operation is mostly appropriate during the spring-summer period providing compensation for the TPP efficiency decrease caused by a low heat output. An increase in GTU, HRSG annual operating time is possible after retrofitting the current TPP-9 thermal scheme allowing operation of GT, HRSG as a power unit with an existing or newly installed steam turbine, which will simultaneously provide an increase in TPP-9 technical and economic indicators as well as equipment readiness and maneuverability. This will provide the opportunity to optimize operation according to the current loads schedule while maintaining the reliable power and heat output.
