Method for controlling a combustion and/or gasification device

Abstract

Combustion and/or gasification devices for the thermal utilisation of different solid fuels, and a method for controlling a combustion and/or gasification device for small-size solid fuels with throw-feeding. A combustion and/or gasification device includes at least one combustion or gasification chamber and a grate with at least two grate zones which are arranged in a longitudinal direction of the grate. A glowing fire edge is formed in one of the grate zones, especially in the so-called burnout zone.

         6 . A method for controlling a combustion device for small-sized, solid fuels with litter feed, the combustion device having at least one combustion chamber and a grid with at least having a pair of grate zones which are arranged in a longitudinal direction of the grid, the method comprising:
 forming a Glutkante in one of the grating zones;   monitoring an actual position of the Glutkante; and   carrying out a regulated change in an amount of an air supply in the combustion chamber for a deviation of the actual position of the Glutkante relative to a target position.   in particular an amount of primary air so-called (PL 1 , PL 2 ) and/or so-called primary recirculation (RL 1 , RL 2 ) in the combustion chamber (BK) is carried out ( 2 ,  3 )   
     
     
         7 . The method of  claim 6 , wherein the monitoring of the actual position of the Glutkante is conducted with at least one optical device. 
     
     
         8 . The method of  claim 7 , wherein the at least one optical device comprises an optical camera. 
     
     
         9 . The method of  claim 6 , further comprising analyzing the actual position of the Glutkante via a processor connected to an optical device. 
     
     
         10 . The method of  claim 9 , wherein the analysis of the actual position of the Glutkante is conducted via color evaluation. 
     
     
         11 . The method of  claim 10 , wherein the color evaluation is conducted via virtual sensors. 
     
     
         12 . The method of  claim 11 , wherein the virtual sensors conduct the color evaluation based upon a good condition, a warning condition and a fault condition. 
     
     
         13 . The method of  claim 12 , further comprising comparing actual color values smaller image segments with predetermined reference color values for the image sections using the virtual sensors that then at exceeding of a freely definable definable threshold value by a color difference between the actual color value and the reference color value the corresponding sensor is placed in the error state, and then determining by an evaluation of the individual sensor states an actual position of the Glutkante.
