Abstract:
A flameless combustion heater system is described that comprises a flameless combustion heater; an oxidant inlet pipe; a fuel inlet pipe; and a preheater for preheating the oxidant or the fuel, said preheater comprising an oxidation catalyst. A method for starting up a flameless combustion heater is described comprising passing a fuel-oxidant mixture to a preheater comprising an oxidation catalyst to preheat the fuel or oxidant stream being fed to the heater. A method for controlling the temperature of the flameless combustion heater system is also described that comprises controlling the amount of fuel and/or oxidant that passes through the preheater.
Abstract:
A control system for an oxy-fuel combustion process is disclosed for use with a boiler or furnace which dynamically controls the flame temperature of each burner involved in the combustion process to dynamically maximize the flame temperature. The boiler or furnace used in conjunction with the combustion process in accordance with the present invention is configured with a radiant, i.e. line of sight, heat zone and a convective heat zone. By dynamically maximizing the flame temperature of the various burners within the boiler or furnace, the radiant heat transfer is optimized. By optimizing the radiant heat transfer within the boiler or furnace, the efficiency of the boiler or furnace is significantly improved.

Abstract:
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.
Abstract:
Control system and method for monitoring and controlling the stoichiometry of a secondary air burner in a thermal oxidizer. The burner control system secures a certain stoichiometry independent of possible simultaneous changes of the gas mixture flow rate and/or of the combustible impurity concentration in the process gas. The firing rate of the burner is adjusted by a controller. Additionally, the flow of the burner fuel and of the process gas mixture are measured and transformed into separate signals. Both signals are sent to an evaluation apparatus that compares the signals and generates a third signal based upon that comparison. This third signal is in communication with a device that changes the gas mixture flow resistance, and thus the desired amount of gas mixture will be diverted for the combustion of the fuel.
