摘要： The invention relates to gas monitoring. Hitherto gas, such as flue gas has been analysed either by sampling and analysing the sample or by a spectrometer. However sampling is unreliable, and spectrography involves sensitive and expensive equipment needing extensive protection against vibration. In the invention, gas is monitored in situ by providing an infra red source and an infra red detector spaced across a gas flow, with a filter cell filled with the gas component to be monitored disposed between them. The detector detects radiation direct from the source and passing through the filter cell, and the outputs from the detector are fed to a differencing and dividing circuit to provide an output that is a function of the amount of monitored gas component in the gas flow.

摘要： The invention relates to monitoring equipment for smoke and/or fine particle emissions from fossil fuel systems, of the type where a beam of visible light is passed across a flue from a light source to a detector, a difference in the light intensity received by the detector from the known intensity of the source indicating absorption of light by smoke and/or fine particles in the flue, and the degree of difference indicating the level of smoke and/or fine particles. The objective of the invention is to provide monitoring equipment of the above type, of simpler, lower cost, more robust nature than has hitherto been provided. The objective is met by a construction comprising two units (1, 2) for location of opposite sides of a flue or chimney each unit comprising a light source, (L.sub.1, L.sub.2) a lens (4) and a light detector (D.sub.1, D.sub.2), the light from the light source of each said unit being directed by its lens across the flue or chimney in a divergence path, to be gathered by the lens of the opposite unit and directed to the detector in the opposite unit, the outputs from the detectors of each unit being combined to provide a reading of the degree of smoke and/or fine particulate material existing in the flue or chimney.

摘要： A method of monitoring a selected flame in a multi-burner furnace comprises positioning two arrays of photoelectric sensors, providing an optical path for the sensors of each array so that the line of sight of one sensor of one array will intersect the line of sight of one sensor of the other array, electronically scanning the two arrays to determine the sensors, one from each array, which give maximum correlation of output signals from the sensors to electronically optimize the signals generated from selected sensors, and electronically locking on to the selected sensors to monitor the selected flame.
