Abstract

1. A process for controlling the excess air in a furnace in which the air flow and/or fuel flow is corrected on the basis of measurement of the excess air in the flue gas after a prescribed value/actual value comparison of the excess air in a control device, the proportional sensitivity (gain) of the control device being varied according to the load rate (beta), and at least some of the time parameters of the control device are automatically adapted to the load rate (beta) of the furnace, the prescribed excess air value (w, w') fed as command variable (reference variable) to a controller (11, 28) of the control device being varied according to the load rate (beta), characterized in that the prescribed excess air value (w, w') is fed to the controller (11, 28) through a signal filter (10, 26) having at least one time constant, at least one of the time constants (TF ) being varied according to the load rate (beta).
