STEAM PLASMA BURNER DEVICE WITH IN-CYCLE GASIFICATION OF FUEL Russian patent published in 2022 - IPC F23C99/00 

FIELD: thermal power engineering.

SUBSTANCE: device relates to thermal power engineering, in particular, to hydrogen energy, and can be used to produce thermal energy from water in addition to the thermal energy of hydrocarbon fuel. A steam plasma burner device with intra-cycle gasification of fuel contains a fire chamber made in the form of a linear chain of Laval nozzles, in which the outlet of the previous nozzle is connected to the inlet of the subsequent nozzle of the chain so that the geometric dimensions of the subsequent nozzle of the chain exceed the geometric dimensions of the previous one. A nozzle is installed at the end of the first nozzle, which has a channel for supplying superheated steam to it, a channel for supplying hydrocarbon fuel and a return channel, and in the critical section zone of the first Laval nozzle, a plasma electrode is installed coaxially with it, electrically connected to a source of plasma-generating electric current and electrically isolated from the first Laval nozzle and the housing covering the linear chain of Laval nozzles, while the firing chamber is equipped with an air channel for supplying air to it and a plasma return channel from the firing chamber to the return channel of the nozzle.

EFFECT: increase in the reliability of the burner device by eliminating the wear of the electrodes and increasing its efficiency by ensuring the maximum possible completeness of the combustion of the hydrocarbon component.
