DEVICE FOR FLAMELESS COMBUSTION OF FLUSH GASES Russian patent published in 2005 - IPC

FIELD: technologies for combustion of flush gases, including those under high pressure, during extraction and processing of natural gas and oil.

SUBSTANCE: body of burner, mounted on gas inlet pipe, is made conical with widened portion at upper portion, in the body additionally mounted are two catalyst elements, at lower portion on inlet section first catalyst element is positioned, and above on outlet section - second catalyst element, rotary shutters are mounted on base of conical body in additional way, so that in closed position they are in contact with first catalyst element, and open position between first catalyst element and body gap is formed, also, device is additionally provided with one or more main torches, mounted in gas inlet pipeline below rotary shutters and first catalyst element. Relation of diameters of first and second catalyst elements matches relation of debits of hydrocarbon gas, fed in normal mode and during salvo exhaust. Catalyst elements are manufactured either in form of cell-like structured blocks with direction of channels in parallel to direction of feeding of flush gases, or in form of block sections with granulated catalyst, for example, Rachig rings, or in forms of block sections with active-catalyst metallic shavings, or in form of blocks with active-catalyst metallic meshes.

EFFECT: higher ecological safety and fullness of combustion of flush gases in broad flow range, simplified construction and comfort of maintenance.
