Turbine exhaust water recovery system

A water recovery system comprising:

• an exhaust duct with a turbine exhaust gas flowing therein, the turbine exhaust gas including water vapor and being at a first temperature;
• a direct contact heat exchanger having an inlet and an outlet, each of the inlet and the outlet being in fluid communication with the exhaust duct, a portion of the turbine exhaust gas being received in the inlet, the direct contact heat exchanger having an upper end and a lower end, wherein the lower end is defined at least in part by a sump;
• and
• at least one water dispensing device provided in the direct contact heat exchanger near the upper end, the at least one water dispensing device being adapted to introduce water into the flow of the turbine exhaust gas, wherein the water engages the exhaust gas so as to reduce the temperature of the exhaust gas so as to condense at least a portion of the water vapor in the exhaust gas, wherein the water collects in the sump.

A stack water recovery system comprising:

• an exhaust duct with a turbine exhaust gas flowing therein, the turbine exhaust gas including water vapor and being at a first temperature;
• a separator;
• a supply conduit extending between and in fluid communication with the exhaust duct and the separator, wherein the supply conduit receives a portion of the turbine exhaust gas and routes the gas to the separator;
• a discharge conduit extending between and in fluid communication with the separator and the exhaust duct, wherein the gas in the discharge conduit reenters the exhaust duct for release into the atmosphere;
• a first heat exchanger provided along the supply conduit upstream of the separator, wherein the supply conduit and the discharge conduit pass in heat exchanging relation through the first heat exchanger, and wherein the first heat exchanger reduces the temperature of the exhaust gas in the supply conduit below the first temperature;
• and
• a second heat exchanger provided along the supply conduit downstream of the first heat exchanger and upstream of the separator, wherein the second heat exchanger further reduces the temperature of the turbine exhaust gas to a temperature below the dew point of the gas, thereby causing at least some of the water vapor in the turbine exhaust gas to condense, wherein the separator removes at least a portion of the condensed water from the gas.
