METHOD AND DEVICE FOR GENERATION OF GAS PULSES Russian patent published in 2009 - IPC B08B5/02 B08B7/02 

FIELD: technological processes.

SUBSTANCE: group of inventions is related to generation of gas phase pulses and may be used in device for cleaning of dust deposits. In method that comprises combustion chamber combined with amplifying flare, combustible gas and oxygen are supplied to prepare mixture into combustion chamber of substantially elongated shape with two opposite ends, mixture is ignited by means of symmetrically installed ignition facilities in ignition zone located near one end of combustion chamber, with provision of initial blasting that results in a pressure wave reflecting from internal walls of combustion chamber end with formation of collision zone, in which initial blasting is at least partially converted into detonation, and pressure pulse is released from combustion chamber and transferred to amplifying flare to create amplified pulse. Besides, wave of mixture combustion is exposed to self-compression due to collision of combustion front in point that is substantially located on central axis of combustion chamber, due to reflection of combustion front from chamber end, where gas and air are supplied, and due to compression of combustion front at the other end of chamber, from which pressure is released into amplifying flare. Device for method realisation comprises combustion chamber of extended shape with two opposite ends, the first of which is arranged with the possibility of combustible gas mixture supply, and the second is made with possibility to release gas pulse generated as a result of gas mixture combustion. Combustion chamber is combined with amplifying flare connected to outlet end of chamber. Chamber also comprises ignition zone located near the first end and equipped with symmetrically installed ignition facilities, and reflection zone created by internal walls of the first end that provides for reflection of gas pressure waves generated as a result of gas mixture ignition. Besides, chamber additionally comprises compression zone located near the second end for compression of gas waves. Method is also presented to cleaning of industrial equipment surfaces having deposits of soot and particles, in which device is used according to invention.

EFFECT: provision of reduced fuel consumption as sound pressure reaches around 160 dB.
