【Author】 Liu Dezhang Wu Xiao (Department of Power Engineering) In this research kerosene is used as coolant for turbine vanes, the key problem for kerosene is its coking property. Although coking does happen under some special conditions, it could be controlled using empirical formulas to make it possible to skip those short coking zones by raising the coolant operating pressure. The suppression method on kerosene coking property has been studied in this paper. The results have been shown that kerosene coking property may be eliminated by raising the coolant operating pressure over 0. 5MPa only. The key problem for kerosene as coolant of high temperature turbine vanes might be solved, and provided as an improtant reference for futher investigation.
