Abstract
The present application provides a hazardous gas detection system to determine hazardous gas concentrations and/or temperatures within a flow of exhaust air in an exhaust duct of a gas turbine compartment. The hazardous gas detection system may include one or more sensors positioned within or in communication with the exhaust duct and a static mixer positioned upstream of the one or more sensors to promote mixing of the flow of exhaust air.
Claims18
A hazardous gas detection system to determine hazardous gas concentrations and temperatures within a flow of exhaust air in an exhaust duct of a gas turbine compartment, comprising:
- one or more sensors positioned within or in communication with the exhaust duct;
- and
- a static mixer positioned upstream of the one or more sensors to promote mixing of the flow of exhaust air, wherein the static mixer comprises a plurality of ducts and wherein each of the plurality of ducts comprises one or more walls comprising a plurality of apertures.
A method of determining a concentration or temperature of a hazardous gas in a flow of exhaust air in an exhaust duct of a gas turbine compartment, comprising:
- pulling the flow of exhaust air into the exhaust duct;
- positioning a static mixer in the flow of exhaust air, wherein the static mixer comprises a plurality of ducts and wherein each of the plurality of ducts includes one or more walls comprising a plurality of apertures;
- uniformly mixing the hazardous gas within the flow of exhaust air;
- and
- sensing the concentration or temperature of the hazardous gas.
