PROBLEM TO BE SOLVED: To provide an improved system for increasing output by wet compression, avoiding problems such as erosion in the root of a first stage rotor blade. SOLUTION: In this wet compression system for a gas turbine compressor, a plurality of nozzles for injecting fine liquid drops are arranged in a rear section of a bell mouth. The rear section of the bell mouth can be arranged in a downstream side half part of the bell mouth, and the nozzles can be connected to a plurality of supports including structural members respectively connecting an inner diameter casing of each bell mouth and an outer diameter casing of the bell mouth to each other. In one execution mode, the nozzles are arranged in the front edge of one or more supports, and the minimum interval at about 0.2m or more is maintained between the inner diameter casing of the bell mouth and the nozzles. In other execution mode, the nozzles are arranged in the rear edge of one or more supports, and the minimum interval at about 0.05m or more is maintained between the inner diameter casing of the bell mouth and the nozzles.
