Abstract
The invention relates to an incineration plant with a furnace, a device for feeding back incineration residues into the furnace, a device for measuring at least one parameter of the incineration, and devices for controlling the incineration. Moreover, the invention relates to a method for controlling an incineration plant.
Claims11
An incineration plant comprising:
- a) a furnace for incinerating combustible materials;
- b) a feeding hopper with an attached feeding chute for feeding the combustible materials onto a firing grate via a feed table;
- c) a thermography camera configured to measure a temperature of a combustion bed of the furnace;
- d) a conveyor device configured to feed incineration residues back to the combustible materials;
- e) a buffer storage for the incineration residues that are to be fed back to the combustible materials;
- f) a plurality of sensors configured to measure a gas content above said combustion bed;
- and
- g) a central computer unit coupled to said thermography camera, to said conveyor device and to said plurality of sensors, said central computer unit configured to:
- receive measured values from said thermography camera, from said conveyor device and from said plurality of sensors, said measured values corresponding to a conveyed amount of incineration residues fed back by said conveyor device;
- generate a control signal for regulating a volume flow rate of the incineration residues fed by said conveyor device based upon said measured values and independently of a rate of the feeding of the combustible materials onto said firing grate via said feed table;
- generate a control signal for regulating a flow rate of primary combustion air based upon said measured values;
- and
- generate a control signal for regulating a flow rate of secondary combustion air based upon said measured values.

A method for controlling an incineration process in an incineration plant, the method comprising the steps of:
- a) providing a furnace for incinerating combustible materials;
- b) feeding the combustible materials from a feeding hopper with an attached feeding chute onto a firing grate of the furnace via a feed table;
- c) measuring a temperature of a combustion bed of the furnace with a thermography camera;
- d) feeding incineration residues back to the combustible materials via a conveyor device;
- e) providing a buffer storage for the incineration residues that are to be fed back to the combustible materials;
- f) measuring a gas content above the combustion bed with a plurality of sensors;
- g) coupling a central computer unit to the thermography camera, to the conveyor device and to the plurality of sensors;
- and
- h) configuring the central computer unit to receive measured values from the thermography camera, from the conveyor device and from the plurality of sensors, the measured values corresponding to a conveyed amount of incineration residues fed back by the conveyor device;
- wherein the central computer:
- generates a control signal for regulating a volume flow rate of the incineration residues fed by the conveyor device based upon the measured values and independently of a rate of the feeding of the combustible materials onto the firing grate via the feed table;
- generates a control signal for regulating a flow rate of primary combustion air based upon the measured values;
- and
- generates a control signal for regulating a flow rate of secondary combustion air based upon the measured values.
