摘要:
The system for continuous thermal combustion of matter, such as waste matter, is provided with an incinerator comprising an inlet, an outlet and a combustion path extending between the inlet and the outlet. The system further comprises air supply means for supplying heated air to the combustion path. The system is further provided with regulating means for automatically regulating the magnitude of the air supply and/or the temperature of the air supplied with the aid of the air supply means, depending on the heating value of the matter (the amount of heat which is generated upon combustion of the matter in the incinerator).

A control system for an incineration plant, comprising an incineration furnace with a combustion path along which the material to be burned is transported, air supply means, a steam generator, and control means with a steam controller and an oxygen controller which, depending on respectively the generated amount of steam and the oxygen in the furnace, generate control signals for adjusting the size and/or speed of a stream of material in the furnace and/or for adjusting the air supplied. The control signals control the generated amount of steam to a first adjusting value and via air supplied the amount of oxygen to a second adjusting value. The steam controller controls a summing device which forms a sum signal used which via calculating means modifies the output signals of control circuits controlled by the output signal of the oxygen controller for the air supply to the furnace and/or the size of the supply stream of material to the furnace and the speed of the stream of material through the furnace respectively, to obtain definitive control signals.

摘要:
The invention relates to a system for thermal combustion processes of matter such as, for instance, waste incineration. The system comprises a computer for measuring parameters of the combustion of the matter, wherein, in use, matter, such as for instance waste, is supplied to the system and combusted, thereby forming a flue gas. The system further comprises means for determining the concentration of CO2, O2 and H2O in the flue gas. The computer is arranged for determining, on the basis of the measured concentrations, the rate of combustion and/or the composition of the combustible part CHyOz of the waste supplied to the system, for the purpose of process control.
