Abstract
Arrangements for withdrawing carefully controlled samples from an active flue gas source are disclosed. A testing assembly is provided for connection to downstream processing equipment to obtain a sample from a gas stream. Included is a probe, a flexible sample line and a coupler joining the probe and the flexible sample line. At least one externally controlled or self-regulating heating cable is put in heating communication with the flexible line. A receptacle engaging the coupler is also provided for positioning the probe with respect to the flue gas source.
Claims9
A system for controlled positioning of a probe with respect to a gas stream, the probe having a first end with a gas inlet and a second end for connection to downstream processing equipment to deliver a sample from the gas stream, comprising:
- a flexible interconnect for connecting the probe to the downstream processing equipment;
- a coupler for joining the second end of the probe and the flexible interconnect;
- the flexible interconnect including at least one gas channel comprising a flexible gas line coupled to the probe to transmit a sample from the probe inlet to the downstream processing equipment;
- at least one heating cable in heating communication with the flexible gas line;
- the flexible interconnect further including an outer sheath surrounding the flexible gas line and the heating cable;
- a thermal insulator disposed within the outer sheath and surrounding the flexible gas line and the heating cable;
- and
- a receptacle for receiving said probe and said coupler, including a lever operated cam spaced a predetermined distance from the gas stream and engaging said coupler so as to position the gas inlet of the probe with a preselected relationship to the gas stream.
