METHOD FOR OBTAINING HIGHLY OVERHEATED STEAM AND DETONATION STEAM GENERATOR DEVICE (OPTIONS) Russian patent published in 2019 - IPC F22G1/00 F22G3/00 

FIELD: technological processes.

SUBSTANCE: invention relates to methods and devices for producing highly superheated water vapor. Method of obtaining highly superheated water vapor from the feed water due to cyclic detonation combustion of a combustible mixture, in which water vapor, preliminarily obtained from feed water, subjected to cyclic or continuous detonation compression in the case when the combustible mixture is mixed with water vapor and is inside the concentration limits of detonation, or cyclic shock compression in the case when the combustible mixture is not mixed with water vapor, and in both cases part of the thermal energy, released during cyclic or continuous detonation combustion of a combustible mixture, is spent on pre-production of water vapor from the feed water using heat transfer. Proposed method is implemented in a device comprising a combustion chamber, a fuel supply system and an oxidizer, an ignition system and a feed water supply system in which the combustion chamber is made either in the form of a pulse detonation tube, or in the form of a continuous detonation combustion chamber equipped with a cooling system, and the feedwater supply system includes a supply tank with a feedwater temperature sensor and a feedwater level sensor, the supply tank is always partially filled with feed water, and the pulse-detonation tube or continuous-detonation combustion chamber and supply lines of the fuel and oxidant supply systems are always immersed in this feed water, and in the upper part of the inlet reservoir, permanently filled with water vapor, there is a steam collector with a valve directing the water vapor to the inlet section of the pulse-detonation tube or the continuous-detonation combustion chamber.

EFFECT: invention is directed to the formation of a dense and long-range jet of highly superheated water vapor for the processing and utilization of solid household and other wastes using oxygen-free technologies.
