Definitions

  • the invention relates to a combustion method wherein a fuel and atmospheric air are introduced into a combustion chamber, wherein said fuel is combusted in said combustion chamber,, wherein combustion gases that are released during combustion are discharged from the combustion chamber, and wherein part of the combustion gases is returned to the combustion chamber.
  • Such a method is known. It is for example used in power stations, process furnaces, larger heating boilers, gas engines and in vehicles fitted with a combustion engine.
  • the combustion gases are partly returned to the combustion chamber so as to prevent the production of nitrogen oxides (NO ) and to reduce the amount of harmful substances such as carbon monoxide (CO) and hydrocarbons (C ⁇ H ) by passing them through the combustion process once again. Said substances are thereby converted into less harmful substances.
  • the percentage of combustion gases that can be returned is limited, however. When the oxygen content in the combustion chamber becomes too low, this will have an adverse effect on the process. Frequently additional measures are required in order to meet the requirements for reduction of harmful emissions, such as fitting filters, catalytic converters, injection of ammonia, etc .
  • another oxygen- containing gas besides atmospheric air is introduced into the combustion chamber.
  • said oxygen- containing contains at least 90% oxygen.
  • the oxygen content of the oxygen-containing gas being carried to the combustion chamber and the combustion gases jointly is about 20% by volume, as in atmospheric air, or substantially equal to the percentage by volume of oxygen that is required for that process, the adverse effects of returning the combustion gases for the combustion process are limited, and a larger portion of the combustion gases can be returned.
  • the invention is in particular suitable for combustion processes wherein the fuel comprises coal, brown coal, coke, fuel oil, natural gas, diesel oil, petrol and/or PG.
  • the fuel comprises coal, brown coal, coke, fuel oil, natural gas, diesel oil, petrol and/or PG.
  • the method is used in a power station, wherein electricity is generated by means of the combustion process.
  • the method is used in a process furnace, wherein a material is heated or dried by means of the combustion process.
  • the method is used is a gas engine .
  • the method is used for driving a vehicle.
  • the method is used in a heating boiler, wherein a space is heated by means of the combustion process.
  • the invention furthermore relates to a combustion apparatus, such as a power station, a process furnace, a gas engine, a vehicle or a heating boiler, comprising a combustion chamber, to which a inlet for a fuel, an inlet for atmospheric air, an exhaust for combustion gases and an inlet for combustion gases are connected, wherein the exhaust for combustion gases is connected to the inlet for combustion gases, and wherein besides the inlet for atmospheric air another inlet for another oxygen-containing gas is connected to said combustion chamber.
  • a combustion apparatus such as a power station, a process furnace, a gas engine, a vehicle or a heating boiler, comprising a combustion chamber, to which a inlet for a fuel, an inlet for atmospheric air, an exhaust for combustion gases and an inlet for combustion gases are connected, wherein the exhaust for combustion gases is connected to the inlet for combustion gases, and wherein besides the inlet for atmospheric air another inlet for another oxygen-containing gas is connected to said combustion chamber.

  • the amount of combustion gases being returned can be adjusted in order to have the engine operate as efficiently as possible.
  • an inlet 7 for atmospheric air and an inlet 8 for oxygen are connected to inlet 3.
  • Oxygen inlet 8 adds practically pure oxygen to the gas mixture consisting of atmospheric air and combustion gases, in such a manner that the oxygen content of the gas picture that is introduced into engine 1 through inlet 3 is sufficient to ensure adequate combustion of the f el.
  • an inlet 10 for fuel and air is connected to the combustion chamber of a furnace 9, as is an exhaust 4 for the combustion gases being produced in furnace 9.
  • part of the combustion gases is returned to the inlet 10 of the furnace via return line 5; the remaining part exits the system via chimney 11.

Abstract

L'invention se rapporte à un procédé de combustion et à un appareil de combustion, du type station énergétique, four de traitement, moteur à étincelles, véhicule ou chaudière de chauffage, dans lequel un combustible et de l'air atmosphérique sont introduits dans une chambre de combustion. Le combustible est soumis à une combustion dans ladite chambre de combustion, les gaz de combustion qui sont libérés au cours de la combustion sont évacués de la chambre de combustion et une partie des gaz de combustion est renvoyée vers la chambre de combustion, de sorte qu'un autre gaz contenant de l'oxygène, en plus de l'air atmosphérique, est introduit dans la chambre de combustion.
