PROBLEM TO BE SOLVED: To provide turbine equipment, an exhaust heat recovering boiler device and an operation method of the turbine equipment, capable of remarkably reducing an attachment rate of scale to a high-pressure water supply control valve. SOLUTION: In this turbine equipment composed of an exhaust heat recovering boiler 2 generating steam from the heat of a heat source through a high-pressure heating unit 3, an intermediate-pressure heating unit 4 and a low-pressure heating unit 5, a steam turbine 6 operated by the steam of the exhaust heat recovering boiler 2, a condenser 8 for condensing the exhaust of the steam turbine 6, and a water supply system for supplying the condensed water 50 condensed by the condenser 8 to an exhaust heat recovering boiler 2 side through a condensing line L<SB>0</SB>, ammonia as an agent 46a is supplied to the condensing line L<SB>0</SB>for supplying the condensed water 50 by an agent injecting means 45 to adjust pH of the supplied water circulated in the water supplying system to 9.8 or more.
