摘要： A burner for use in a combustion system of an industrial gas turbine. The burner includes a fuel/air premixer including a splitter vane defining a first, radially inner passage and a second, radially outer passage, the first and second passages each having air flow turning vane portions which impart swirl to the combustion air passing through the premixer. The vane portions in each passage are commonly configured to impart a same swirl direction in each passage. A plurality of splitter vanes may be provided to define three or more annular passages in the premixer.

摘要： An aspirating or suction pyrometer for measuring hot combustion gases. A thermocouple in the pyrometer has a temperature sensitive junction formed of platinum alloys. The thermocouple junction is insulated and is encased within a platinum alloy sheath. The sheathed thermocouple is mounted within inner and outer tubular radiation shields. These shields are formed of a platinum alloy having a radiation emissivity substantially the same as the thermocouple. The shields block radiated heat from the flame and combustion chamber from being transferred to the thermocouple. The radiation shields do not themselves radiate heat to the thermocouple because the shields and thermocouple are at the same temperature and formed of substantially the same noble alloys.
