Patent ID: 7845291

Claim:
A combustion control system for operating a waste incineration plant with a furnace, the combustion control system comprising: an auxiliary burner being substantially separated from the furnace and being ignited to maintain a minimum firing temperature; a steam controller which receives as input variables a steam power from a steam sensor assigned to a steam generator of the waste incineration plant and a steam power desired value, the steam controller generating set values for at least one of a primary-air stream, a secondary-air stream, a grate stroke frequency and a ram speed of the waste incineration plant as actuators; and a burner power compensation unit which receives a measured burner power of the auxiliary burner as an input variable and the output variable of which is supplied to the steam controller that regulates the steam power as a function of the burner power of the auxiliary burner, the measured burner power being determined based on an actual fuel consumption of the auxiliary burner, wherein a calculation of a burner steam power generated by the auxiliary burner takes place as a function of the burner power, and wherein the burner steam power is utilized for calculating a corrected steam power desired value and a waste steam power desired value.
