Patents by Inventor Alfons Schirmer

Alfons Schirmer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6752093
    Abstract: A method for operating a refuse incineration plant and to a regulating system, in which, after the fire has been fanned, the generation of heat is made more uniform by regulating at least one of the following operating parameters: refuse metering; residence time on a grate; quantitative supply of primary air; and quantitative preheating of primary air. To match the operating parameters to a varying calorific value of the refuse, the calorific value of the refuse is recorded as well as the standard regulating variables and is used to adapt the regulating device. The measure used for the calorific value is, for example, the moisture content of the flue gas generated during the incineration. Consequently, there is no need for the operator to estimate the calorific value and manually adapt the operating parameters accordingly.

To match the operating parameters to a varying calorific value of the refuse, the calorific value of the refuse is recorded as well as the standard regulating variables and is used to adapt the regulating means. The measure used for the calorific value is, for example, the moisture content of the flue gas generated during the incineration. Consequently, there is no need for the operator to estimate the calorific value and manually adapt the operating parameters accordingly.

  • Patent number: 5230293
    Abstract: A multi-loop control system and a method for using the control system to even out the generation of heat produced by a refuse incineration plant. The quantity of steam generated is controlled as a primary controlled variable and the oxygen content of the flue gas is controlled as a secondary controlled variable. This method makes it possible to improve other parameters in operating a refuse incineration plant.
