ABSTRACT:
A seal device for use in a rotary type regenerative heat exchanger which is used for a gas turbine. This device consists of a seal-member urging mechanism adapted to urge the seal member against the flat surface portion of a heat-exchanger core, and a control mechanism which maintains a drive torque of a heat-exchanger core at an optimum value by operating the seal-member urging mechanism by comparison of a preset reference signal value with a signal of a value proportional to a drive torque required for driving the heat-exchanger core. The control mechanism further consists of a fluid pressure generating device such as for air or oil pressure and a mechanism for controlling the pressure within the fluid-pressure generating device.
