PROBLEM TO BE SOLVED: To provide a deicing device lightening weight in small size and enhancing reliability of a control system, by decreasing a space occupied by an equipment except an anti-freezing fluid tank and a fresh water tank, in the deicing device removing ice and snow on an object by jetting extraction air (bleed air) of a gas turbine from a nozzle, and mixing an anti-freezing fluid and fresh water kept at a fixed temperature, so as to deliver this mixture fluid. SOLUTION: A heat exchanger is provided in an anti-freezing fluid tank and a fresh water tank, a pump for supplying a fluid in these tanks to a nozzle and a gas turbine 21 serving as a drive source of this pump are provided, exhaust of this gas turbine is allowed to flow in heat exchangers 34, 35 while controlling switching of a switching valve, so as to fixedly hold a temperature of anti-freezing fluid and fresh water, and so as to jet bleed air of the same gas turbine from the nozzle. |
