Abstract

PURPOSE: To keep off any condensation of a sulfide to a fuel economizer tube as well as to avoid getting any corrosion by controlling a temperature of fed water for an exhaust heat recovery boiler into the specified value different at each time of using high sulfur content fuel and low sulfur content one for a gas turbine.
CONSTITUTION: Fuel uninclusive of sulfur content is fed to a combustor 40 of a gas turbine 1 from a fuel feed valve 3 and fuel inclusive of it from a fuel feed valve 4, respectively. At this time, in case of the fuel uninclusive of the sulfur content, thereif no fear of any condensation of a sulfide against the tube of a fuel economizer 12 in a exhaust heat recovery boiler 11 so that internal pressure in a deaerator 21 is regulated to, for example, 0.2 atmosphertic pressure or so by a pressure regulator 23, and a temperature of feed water out a feed water pump 22 is set to about 60°C. On the other hand, at time of using the fuel inclusive the sulfur content, in order to avoid any condensation of a sulfide to a steam tube, setting valve of the pressure regulator 23 is altered to, for example, 1.4 atmospheric pressure so as to cause this feed water temperature to become such a temperature, for example, 120°C that the sulfide is not dewed in the fuel economizer 12.
