Abstract
The occurrence of excessively high temperatures in areas of a generator exposed to a cooling gas stream is visually indicated by passing a portion of the gas stream through an indicator device which comprises a filter holder containing a gas-permeable, particulate-collecting filter on which is an indicator which produces a visual effect when contacted by particulates. A valve controls the flow of the gas to the device and is opened by a monitor when the monitor detects particulates in the gas stream.
