Influence of Gland Leakage on Economy of Unit

Abstract

Abstract: The designed heat consumption rate of supercritical steam turbine generation unit has higher circulation thermo-economy, but sometimes this advantageous was not realized in practical operation. In this paper the author took a unit as an example, analyzed the influence of gland seal leakage in high pressure parts on economy of the unit, and gave some concrete influence values quantitatively, the results can be used as a reference for the similar units.

Key words: supercritical unit, high pressure (HP) cylinder, gland seal, economical influence, analysis
