POWER GENERATION SYSTEM HAVING AN EXHAUST GAS ATTEMPERATING DEVICE AND SYSTEM FOR CONTROLLING A TEMPERATURE OF EXHAUST GASES

摘要

An exhaust gas attemperating device is provided. The exhaust gas attemperating device includes a conduit in fluid communication with a gas turbine. The conduit is configured to receive exhaust gases from the gas turbine and has one or more apertures extending therethrough. The exhaust gas attemperating device further includes one or more atomizing nozzles extending through the apertures of the conduit. The atomizing nozzle is configured to inject a liquid through the aperture into the conduit, such that the liquid evaporates and decreases a temperature and an oxygen concentration of the exhaust gases in the conduit.
