Gas turbines are commonly used in propulsion of aircraft, land-based power generation and various industrial applications. Gas turbine working at high-temperature limits. In order to achieve the good performance of the gas turbine, the temperature at the inlet of the turbine should be increase. This high temperature mainly effects the blades of the gas turbine and leads to destroy the turbine blades. To reduce the effect of high temperature, a cooling method is required for gas turbine blades. In this review mainly focused on various cooling techniques like air cooling, steam as cooling medium and coolant paint in air medium were discussed for cooling of the gas turbine blades. Cooling of turbine blades under air as cooling medium and steam as cooling medium are discussed by three different techniques of each like air internal convective cooling, air film cooling and air transpiration cooling under air as cooling medium steam internal convective cooling, steam film cooling and steam transpiration cooling respectively under steam as cooling medium. Also, the parameters like heat transfer, efficiency, temperature reduction on turbine blades, and power output varying due to these coolant methods were discussed. Steam as cooling medium gives best results among the all cooling techniques of turbine blades.
