FLAME SCANNER COLLIMATOR BODY

摘要

A flame scanner collimator (201), which monitors flames produced by a fossil fuel fired combustion chamber (117), includes: a substantially cylindrical collimator body (300) defining a hollow portion; a first chamber (302) connected to a second chamber (304), the first and second chambers (302, 304) defining the hollow portion, the second chamber (304) having a larger diameter than the first chamber (302); and a plurality of slots (360) each extending in substantially a same direction as a longitudinal axis (362) defining the body (300). Each slot (360) extends through the body (300) to the first and second chambers (302, 304) to allow cooling/purge air flow therethrough.
