The utility model provides a IGCC power station energy -saving type starting drive is connected to form by coal gasification unit, empty subdivision, gas turbine, gas turbine generator, after burningfan, afterburner, exhaust -heat boiler, steam turbine, turbo generator and flare tower, when the power station starts, at first start empty subdivision and coal gasification unit, then the synthetic gas that utilizes the coal gasification unit to produce sends into after -burning device and start exhaust -heat boiler and steam turbine power generation system, after gas turbine starts and switch into synthetic gas fuel by the time, amputate after -burning device again and move, in having removed conventional start -up course, the order restriction that gas turbine at first starts must be waitedfor to exhaust -heat boiler and steam turbine, and the steam turbine can be in advance starts in gas turbine, shorten full factory activation time, and gas turbine lights a fire back load up in -process and has saved and wait for the steam turbine warm -up, dash the link of changeing and being incorporated into the power networks in addition, and gas turbine is load up and carry out the fuel switching rapidly, and energy -conserving effect is showing.
