The invention solves the problem of production of inert gases by way of liquid fuel combustion and diffusion of combustion products with water in a device having small overall dimensions and ensuring to obtain and pump large quantities of gases with the oxygen content well below 2% of the volume as well as minimum content of unburnt fuel particles and, furthermore, devoid of dissociation products. The device consists of a turbo-compressor and tightly connected chambers for oxygen pre-reduction, fuel atomizers, combustion, mixing, after burning and diffusion cooling. The pre-reduction chamber preferably has four flame tubes with fuel injectors and sparking plugs and the chamber of the fuel atomizers in equipped with two circumferential rows of atomizers. One of thereof is a row of counter-current atomizers located opposite the exhaust gas outlet from the flame tubes whereas the forms a row of parallel-current atomizers placed in the channels which are made up between the partitions that support the internal tube. Behind the chamber of atomizers on the outlet way of exhaust gases, that have undergone pre-reduction from oxygen, two further chambers are situated, the first of these equipped with parallel-current atomizers of additional fuel with sparking plug makes up the combustion chamber, the second fitted at the front with a diffuser and a counter-current central water nozzle forms the after-burning and preliminary cooling chamber before the basic diffusion cooling and evaporation in the last chamber. |
