Abstract (en)

[origin: EP0352619A2] The process for regulating the firing power in combustion plants, in particular in refuse combustion plants, in which process the measured O2-moist content of the flue gas is used as higher-order set point controlled variable for regulating the fuel supply and the measured steam flow rate as lower-order set point controlled variable (10) for regulating the primary air supply, provides, in accordance with a first variant, for the specified O2-moist set point (7) to be varied as a function of the combustion chamber temperature (6) measured in the flue gas. This varied controlled variable (9) is fed to a regulator (13) which influences the fuel feed and/or the grate drive. <IMAGE>
