General Electric Company - Schenectady NY
International Classification:
B08B 9/027, B08B 7/02, G01N 1/22, F23J 3/00
US Classification:
73 2331, 15 94, 1510405, 15406, 7386381, 134 221, 134166 C
Abstract:
An apparatus for cleaning a continuous emissions monitor system that is in fluid communication with a flue stack conducting exhaust gas from a combustion source. The apparatus comprises a housing and a probe mounted in the housing. The probe is tubular and in fluid communication with the flue stack to acquire a sample of gas from the flue stack. The probe tends to have deposits from the exhaust gas accumulate on the inner walls of the probe. A device imparts cleaning energy to the probe for dislodging accumulated deposits from the inner walls of the probe.
Calibration System And Method Of Using Mid-Ir Laser Measure And Monitor Exhaust Pollutant
US Patent:

Assignee:
General Electric Corporation - Schenectady NY
International Classification:
G01N 21/93
US Classification:
73 103
Abstract:
A method is provided of calibrating a system that detects presence of a pollution component within exhaust gases proceeding along an exhaust passageway. A measurement cell of a probe is isolated by movement of either the entire probe or a shield within the probe from the exhaust gas to allow reference gas to be detected by a laser beam in the mid-infrared range in the measurement cell to calibrate the system. In another example, a laser source is placed on one side of an exhaust passageway and a detector is placed on the other side. A reference cell is provided that is used to receive reference gas and calibrate the system. In yet another example, the exhaust gas is extracted from the passageway and is measured in a reference cell. The reference cell is also filled with reference gas when it is desired to calibrate the system.
Calibration Checking For Continuous Emissions Monitoring System
US Patent:
2008028, Nov 20, 2008
Filed:
May 15, 2007
Appl. No.:
11/803617
Inventors:
Mark Holt - Emmaus PA, US
William Eberhardt - Cherry Hill NJ, US
William Eberhardt - Cherry Hill NJ, US
International Classification:
G01N 33/00, G01N 33/22
US Classification:
73 103, 73 2331
Abstract:
A continuous emissions monitoring system is in fluid communication with a flue stack conducting exhaust gas from a combustion source. The continuous emissions monitor system comprises an analyzer for measuring concentrations of an analyte present in the exhaust gas. A probe is in fluid communication with the flue stack to acquire a sample of exhaust gas from the flue stack. The probe is also in fluid communication with and located upstream of the analyzer. The probe tends to remove analyte from the sample. A calibration checking system is in fluid communication with the probe. The calibration checking system includes a source that provides a flow of a known concentration of calibration material to be measured by the analyzer. The calibration material is the same as the analyte. A humidifier is associated with the source to provide moisture to a flow of calibration material. The moisture acts to cleanse removed analyte from the probe and thereby enable an accurate measurement of the concentration of the calibration material.

Assignee:
General Electric Company - Schenectady NY
International Classification:
F02C 1/00
US Classification:
60772, 60 395, 60773
Abstract:
Systems and methods for controlling combustion emission parameters associated with a gas turbine combustor. The method can include providing an optical path through a gas turbine exhaust duct, propagating light along the optical path, measuring exhaust species absorption of the light within the gas turbine exhaust duct, and controlling at least one of the combustion parameters based at least in part on the measured exhaust species absorption.
Mercury Ionic Gas Standard Generator For A Continuous Emissions Monitoring System
