    Patent number: 7302182
    Abstract: A method and system provide for sensing multiple wavelengths simultaneously in a single wavelength sensing device. The system may have a plurality of laser signals and a plurality of identifiable modulation signals. A respective laser signal of the plurality of laser signals is combined with a respective identifiable modulation signal of the plurality of identifiable modulation signals so that each of the laser signals is identifiable. A combined optical signal is then formed from the modulated laser signals. A sensor has an input port that receives the combined optical signal. The sensor identifies, for each of the modulated laser signals, a respective laser signal via the identifiable modulation of the respective modulated laser signal.

  • Method for oxy-fuel combustion
    Patent number: 7282171
    Abstract: An oxygen fueled combustion system includes a furnace having at least one burner, an oxygen supply for supplying oxygen having a predetermined purity, and a carbon based fuel supply for supplying a carbon based fuel. The oxygen and the carbon based fuel are fed into the furnace in a stoichiometric proportion to one another to limit an excess of either the oxygen or the carbon based fuel to less than 5 percent over the stoichiometric proportion. The combustion of the carbon based fuel provides a flame temperature in excess of 4500° F. The exhaust gas stream from the furnace has substantially zero nitrogen-containing combustion produced gaseous compounds from the oxidizing agent and reduced green-house gases. Substantially less carbon based fuel is required than conventional combustion systems without a loss of energy output.
