Calculation for Thermal Parameters of Steam in the Flow Passages of 1000MW Turbine under Variable Operating Conditions

Abstract:

Aiming at a high-power turbine of a certain 1000MW electric-generating unit, three calculation schemes were programmed to calculate the thermal parameters of steam in the flow passages. The comparison and analysis between the calculating results and the design values under the turbine rated load (TRL) verified the feasibilities of the calculation schemes. The thermal parameters of steam in flow passages under variable operating conditions were also obtained by the calculation. The calculating results could be the basic data needed by thermal stress analysis and life prediction of the turbine.
