A method for controlling a gas turbine when the gas turbine is started may include measuring the number of rotations of the gas turbine, determining a target acceleration rate based on the number of rotations of the gas turbine, measuring a current acceleration rate, determining a flow rate of fuel based on a difference between the current acceleration rate and the target acceleration rate, and supplying fuel to the gas turbine at the determined flow rate. The flow rate of the fuel may be determined between a maximum flow rate of the fuel that has been previously stored and a minimum flow rate of the fuel. A temperature of the exhaust gas after controlling the flow rate of the fuel may be monitored.

Method and apparatus for controlling gas turbine when gas turbine is started

A stack fastening device includes a base, on an upper surface of which a stack is loaded, a compression plate, which has a flat configuration and is placed over the stack to press the stack, and a plurality of vertical beams, which are installed on the base to extend vertically so that the upper end portion of the beams projects out through the edge of the compression plate, A thread is formed in an upper end portion of each vertical beam, nuts are threadedly coupled to the thread such that the nuts can be tightened against upper and lower surfaces of the compression plate, and engagement grooves are defined in the upper surface of the compression plate so that a head of a hydraulic cylinder can be coupled to the compression plate.
