Abstract
An exhaust gas purification device (26) for a gas turbine engine (10) comprises a catalyst chamber (64, 96) defined in an exhaust gas passage (22), a reduction agent container (32) containing a solid material that releases a reduction agent gas effective for NOx reduction when heated, a heating device (36, 38) for heating the solid material contained in the reduction agent container, and a reduction agent gas supply passage (48) for supplying the reduction agent gas released from the solid material into the catalyst chamber.
Claims9
An exhaust gas purification device for a gas turbine engine, comprising:
- a catalyst chamber containing a reduction catalyst therein and defined in an exhaust gas passage conducting exhaust gas discharged from the gas turbine engine;
- a reduction agent container containing a solid material that releases a reduction agent gas effective for NOx reduction when heated;
- a heating device for heating the solid material contained in the reduction agent container;
- and
- a reduction agent gas supply passage for supplying the reduction agent gas released from the solid material into the catalyst chamber,
- wherein the exhaust gas purification device further comprises a hydrogen gas source and a hydrogen gas supply passage for supplying hydrogen gas from the hydrogen gas source into the catalyst chamber, and
- the hydrogen gas source comprises hydrogen compound in solid form that releases hydrogen gas by adding water or heating.
