PURPOSE:To maintain the cooling effect and prevent deposits caused by burning heavy oil from adhering to the blade surface, in a heavy oil burning gas turbine cooling blade. CONSTITUTION:Relatively larger cooling holes 5 through which a cooling jet is blown out at an acute angle to the blade surface, are drilled on the belly part of a hollow stationary blade 1, and downstream of the holes, relatively smaller holes 6 through which a cooling jet is blown out at a more acute angle to the blade surface, is provided so that an air jet can be discharged along the blade surface.
