1. A process for the removal of flammable gas mixtures in a gas space, comprising the steps of: separating off a part region of the gas space by grilles having mesh-works made from metal wires, said mesh-works having mesh widths between 0.05 mm and 0.7 mm; and  executing a combustion in the part region.  a combustion chamber;  a plurality of grilles for defining said combustion chamber wherein each grille includes a metal mesh-work, a mesh width of said mesh-work being between 0.05 mm and 0.7 mm; and  means for initiating combustion in said combustion chamber.  a contact sensor for sensing contact between an inner and an outer grille; and  a switch controlled by said contact sensor for interrupting electric current to said means for initiating combustion.  a switch controlled by said temperature sensor for interrupting electric current to said means for initiating combustion.  a plurality of devices, each device comprising:  a plurality of grilles for defining said combustion chamber wherein each grille includes a metal mesh-work, a mesh width of said mesh-work being between 0.05 mm and 0.7 mm; and  a common electrical lead for supplying electricity to the plurality of devices wherein the common electrical lead includes branch leads to each of the devices; and  electronic delay devices arranged in the branch leads; 2. The process of claim 1, wherein the step of executing a combustion includes the step of initiating the combustion by sparks. 3. The process of claim 1, wherein the step of executing a combustion includes the step of effecting the combustion by means of catalytic surfaces. 4. The method of claim 1, wherein the step of executing a combustion includes the step of initiating the combustion by a hot surface. 5. The method of claim 1, wherein the step of executing a combustion includes the step of initiating the combustion by naked flames. 6. The process of claim 1, further comprising the step of selecting the shortest distance between a point of ignition and the grilles such that a discontinuous, explosion-like combustion of the gas mixtures occurs in the part region. 7. An apparatus for removing a flammable gas mixture in a gas space, comprising: 8. The apparatus of claim 7, wherein the means for initiating combustion includes a sparking plug. 9. The apparatus of claim 7, wherein the means for initiating combustion includes a glow plug. 10. The apparatus of claim 7, wherein the plurality of grilles include sinner grilles and outer grilles, the inner and outer grilles being electrically insulated from one another and made of electrically conductive material, the apparatus further comprising: 11. The apparatus of claim 10, further comprising a temperature sensor for sensing temperature on a grille; and 12. The apparatus of claim 11, wherein the temperature sensor senses temperature on an inner grille. 13. The apparatus of claim 11, wherein an ignition sequence frequency of the means for initiating combustion is controlled by an output signal of the temperature sensor. 14. The apparatus of claim 7, further comprising fusible cut-outs which are thermally conductive connected to a grille and electrically connected to said means for initiating combustion, said fusible cut-outs having a fusion temperature that is approximately 3/4 of an ignition temperature of the flammable gas mixture. 15. An apparatus according to claim 11, wherein said means for initiating combustion includes a controllable naked flame which is controlled to open or close by an output signal of the temperature sensor. 16. An apparatus according to claim 7, further comprising baffles for producing a gas mixture flow through the combustion chamber and wherein the baffles are located outside the combustion chamber. 17. The apparatus of claim 7, further comprising fans for producing a gas mixture flow through the combustion chamber and wherein the fans are arranged outside the combustion chamber. 18. The apparatus of claim 16, wherein the baffles extend upwardly from said combustion chamber so that the gas mixture flow through the combustion chamber rises due to the chimney effect. 19. The apparatus of claim 7, further comprising a heat removal device for removing heat from a grille. 20. The apparatus of claim 19, wherein the heat removal device includes a heat pipe. 21. The apparatus of claim 7, wherein the metal mesh-work is made of stainless steel. 22. The apparatus of claim 7, wherein the combustion chamber has a large surface area and a small height. 23. The apparatus of claim 7, further comprising temperature sensors located above an below said combustion chamber for comparing gas temperatures above and below the combustion chamber. 24. The apparatus of claim 7, further comprising electromagnetic radiation sensors for detecting electromagnetic radiation which is emitted during the combustion or absorbed by reaction product. 25. An apparatus for removing a flammable gas mixture in a gas space comprising:
