    • The system for continuous thermal combustion of matter, such as waste, comprises an incinerator, air supply means for supplying heated air to the incinerator, and a steam generator for generating steam on the basis of heat generated in the incinerator. The system further comprises a controller which generates at least one control signal for setting the magnitude of a supply stream of the amount of material to the incinerator and/or for setting the amount of air which is supplied to the incinerator by means of the air supply means. The controller controls the at least one control signal, such that by the steam generator an amount of steam per unit time is generated which is equal to a first value and/or that by the air supply means so much air is supplied that an amount of oxygen is present in the incinerator which is equal to a second value. The system further comprises at least one protective circuit which lowers the first value or the second value when the at least one control signal exceeds a predetermined maximum value.

    • 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.

    • A combustion control method for refuse incinerators stabilizes a burning state to generate a predetermined amount of steam in a refuse incinerator which makes use of heat of combustion for steam power generation. The method comprises determining a weight of refuse charged and a level change before and after the charging of refuse from measurements of a refuse load cell attached to a refuse charging crane and a refuse level meter (12), which measures a surface level of refuse in a refuse incinerator hopper, to control a speed of a drying fire grate (3a), which serves to feed refuse into the incinerator, based on a result of comparison between quantities determined in a plurality of preceding charges and the quantities determined at the present time. Also, the method comprises measuring a quantity of steam generated in the refuse incinerator and an O2 concentration in an exhaust gas, calculating a target quantity of combustion air required for having the generated steam quantity agree with a target quantity of steam generated, setting a target quantity of combustion air, when a measurement of O2 concentration in the exhaust gas first reaches a predetermined upper limit value, as a temporary set quantity of combustion air, controlling a quantity of combustion air so as to have the same agree with the target quantity of combustion air when the measurement of O2 concentration in the exhaust gas is equal to or less than the upper limit value, and controlling a quantity of combustion air so as to have the same agree with a smaller one of the target quantity of combustion air at that time and the temporary set quantity of combustion air when the measurement of O2 concentration in the exhaust gas exceeds the upper limit value.
