摘要： The invention relates to a flame monitor for an oil- or gas-operated burner, having a photosensor which detects the optical flame radiation and an evaluation circuit which is connected downstream of said photosensor and ascertains whether the radiation received by the photosensor corresponds to that of a burning flame and, in the event of a negative result, generates a switch-off signal for the fuel supply, wherein the evaluation circuit determines the number of zero crossings of the processed signal of the photosensor within a predetermined unit of time and compares it with a predetermined limit value, a switch-off signal for the fuel supply being generated when said limit value is undershot, the signal of the photosensor, freed from the DC voltage component and noise, being processed by corresponding amplification to form square-wave pulses.

摘要： A method and an apparatus for sorting particulate solids material. The material is subjected to a microwave field and absorbs energy to an extent depending upon the dielectric properties of the individual particles. The absorbed energy heats the particles, and pyrodetectors detect the heat radiation. Detector output signals control pressurized air jets to remove particles from the waste material which are detected to be colder than the remainder of the bulk.

摘要： The combustion of fuel having a highly fluctuating thermal value is controlled to permit optimization of air supply and reduction of waste gas impurities. The fuel passes through a combustion chamber having a degassing and evaporation zone, a primary combustion zone, and a secondary combustion zone. Measurements are taken in the evaporation and degassification zone to determine the thermal value of the fuel. This is done by detecting the intensity of H.sub.2 O and/or CO.sub.2 spectra emanating from the fuel. The measurement results are utilized to optimize the combustion parameters. Such measurements are also made in the following zones in order to provide further control of the combustion process.
