Taking experimental contrasting method，it compares two different TCA cooling water pump allocation scheme of M701F4 gas turbine which are supplying water with separated TCA cooling water pump or from outlet of high pressure feed pump. The advantages and disadvantages of 2 schemes are analyzed from economy and security under two common working conditionsstarting procedure and normal operation.
