Title:
PREDICTIVE MODEL TYPE CONTROL SYSTEM FOR HIGH HORSEPOWER GAS TURBINE
Document Type and Number:
Japanese Patent JP2008180220
Kind Code:
A
Abstract:

To provide a system for controlling a clearance between a turbine blade and a turbine casing.

This system includes an impingement cooling manifold 140 attached to the turbine casing 120, a temperature detection device for measuring a temperature of the turbine casing 120, a blower 130, a control system 700 logic for determining a setting temperature of the casing 120 and a control device 710 for controlling the blower 130 to cool the casing 120 to a set temperature by forcibly sending air to the impingement cooling manifold 140 by the blower 130 and to control the clearance 128.
