Abstract
PURPOSE: To effect the control of spray water with certainty by, means of controlling the spray regulating valve of ON-OFF operation by making the exhaust temp., exhaust pressure, and the output of the generator into control elements.
CONSTITUTION: When the spray ejecting signal is approved against the rising of the exhaust temp. during the turbin is in operation, an electromagnetic valve 24 is excited, and an air signal 25 opens a spray regulating valve 26, thereby spray water is ejected. And when an operation circuit 29 found from an exhaust air pressure signal 27, and the output signal 28 of generator, is approved as a spray ejecting signal, it becomes to the backup condition of a measured exhaust air ejecting signal 21. On the other hand, the stopping of spray water is effected by means of closing a spray regulatin valve 38 by an air signal 37 by exciting an electromagnetic valve 36 only when the AND condition of a spray ejecting stopping signal 32 due to the actual measured exhaust air temp. and a spray ejecting stopping signal 31, is approved.
