GAS GENERATOR Russian patent published in 2012 - IPC B01J7/00 F23C99/00 

FIELD: process engineering.

SUBSTANCE: proposed invention relates to generators of inert gas nitrogen for various processes. Gas generator comprises casing, ignition plug, combustion chamber, cylindrical baffle, fluid fuel feed branch pipe, coupling nut and air feed branch pipe. Gas generator air flow swirler is made up of two parts with three rows of holes. Note here that first row of holes is made on outer cylinder. Second row of holes is arranged in combustion chamber on smaller inner cone while third row of holes is located on larger cone of combustion chamber. Besides, combustion chamber comprises quick-change injectors for various types of fluid fuel.

EFFECT: easier repair and development of gas and oil wells using inert gas with high concentration of gas nitrogen in gas-fluid mix.
