Title: Method of absorbance correction in a spectroscopic heating value sensor

Abstract

A method and apparatus for absorbance correction in a spectroscopic heating value sensor in which a reference light intensity measurement is made on a non-absorbing reference fluid, a light intensity measurement is made on a sample fluid, and a measured light absorbance of the sample fluid is determined. A corrective light intensity measurement at a non-absorbing wavelength of the sample fluid is made on the sample fluid from which an absorbance correction factor is determined. The absorbance correction factor is then applied to the measured light absorbance of the sample fluid to arrive at a true or accurate absorbance for the sample fluid.

  • This patent describes an internal combustion engine which consists of an exhaust system and an oxygen sensor fitted to the exhaust system, the sensor comprising a sensor element, an electrically powered resistive heater for heating the sensor element, and a source of electrical power to the heater: a method for controlling a value of electrical power supplied from the source to the heater, the method comprising the steps of: controlling the electrical power supplied to the heater according to engine operational parameters; and restricting the controlled electrical power supplied to the heater less than a predetermined maximum tolerable value whenmore » and only when the heater is not warmed to a predetermined active temperature.« less
  • A method is described for controlling electrical power supplied to an electrically powered heater incorporated in an oxygen sensor element in an exhaust system of an internal combustion engine. The heater is adapted to heat oxygen sensing elements such as electrodes and exhaust gas dispersing layers of the oxygen sensor when the heater is supplied with electrical power. The method described here comprises: determining the temperature of the engine at the time of starting up the engine, and only if the temperature of the engine at the time of starting is less than a certain value, providing the heater withmore » electrical power to the maximum practicable amount for a certain continuous time duration after the engine is started up.« less
  • A system for real-time monitoring of flame properties in combustors and gasifiers which includes an imaging fiber optic bundle having a light receiving end and a light output end and a spectroscopic imaging system operably connected with the light output end of the imaging fiber optic bundle. Focusing of the light received by the light receiving end of the imaging fiber optic bundle by a wall disposed between the light receiving end of the fiber optic bundle and a light source, which wall forms a pinhole opening aligned with the light receiving end.
  • Eaton Corp.'s method for determining the calorific value of a fuel gas uses a calibration point that is at or below the lower explosive limit (LEL) of the air/gas ratio rather than some point within the explosive range. Fuel gas of a known Btu content is mixed with air in a controlled ratio and fed into a commercially available combustibility meter, where the mixture is adjusted until the meter indicates the desired setpoint. The unknown fuel gas is then fed into the meter at the same controlled air/fuel ratio. The percentage of LEL now indicated by the meter is usedmore » to calculate the heating value of the new gas.« less
  • The preferred embodiment of the invention disclosed herein includes apparatus for and steps of separating glass, metal and other generally non-combustible material from refuse to provide a volume of generally combustible refuse, shredding this volume of combustible refuse into relatively small particles, mixing these particles with primary combustion air and conveying the resultant mixture of air and particles into a combustion chamber. The combustion chamber is preheated by auxiliary heating means to a temperature sufficient to cause the mixture to be self-igniting in the combustion chamber. Secondary combustion air is fed to the combustion chamber at spaced-apart points within themore » chamber for assuring a complete combustion process. This chamber is maintained under a negative pressure by a fan downstream and the combustion gases are thus caused to flow from the combustion chamber to an associated device utilizing the heat energy, for example, a steam boiler, and from the steam boiler, the gases are exhausted through a stack to the atmosphere. Oxygen measuring means is located on the discharge side of the boiler for measuring the amount of excess oxygen discharged to the atmosphere. In response to this measurement, the feed rate of the shredded particles of refuse is adjusted to maintain a substantially constant amount of excess oxygen in the combustion gases whereby the B.T.U. Output is controlled.« less
