Abstract

PURPOSE: To improve a safety over a selection of the gas fuel by a method wherein a requisite volume of nitrogen purge is judged and if the nitrogen purge is required, an alarm is given to the operator and a selecting operation for the gas fuel may be performed only after the nitrogen purge is completed.
CONSTITUTION: When a different kind of gas fuel is selected before the nitrogen purge is performed, the relay 24 is energized to make an alarm of "nitrogen purge is required". When "nitrogen purge is required" is generated and the operation of the nitrogen purge is started, the relay 24 is not energized and the alarm is released. When the nitrogen concentration becomes sufficiently high and a desired value of concentration is sensed, both the nitrogen inlet valve and the nitrogen outlet valve are fully closed. When both nitrogen inlet valve and nitrogen outlet valve are fully closed, the nitrogen purge is completed to enable a selection of a different kind of gas fuel. After the fuel is changed, the turbine is started to operate.
