Patent ID: 8083519

Claim:
A gasification reactor system for gasifying a feedstock, said gasification reactor system comprising: a first stage reactor section defining a first reaction zone, wherein said first stage reactor section comprises a plurality of inlets operable to discharge said feedstock into said reaction zone; a burner disposed in each of said inlets, wherein each burner comprises a body defining an oxidant inlet, an uncombusted feedstock inlet, a body outlet, and one or more passages for conveying said oxidant from said oxidant inlet to said body outlet and for conveying said uncombusted gasification feedstock from said feedstock inlet to said body outlet, said body lacking an igniter for igniting the uncombusted gasification feedstock within the body; a nozzle defining a nozzle inlet and a nozzle outlet, wherein said nozzle inlet is configured to receive said oxidant and said uncombusted gasification feedstock from said body outlet and said nozzle outlet is configured to discharge said oxidant and said uncombusted gasification feedstock into said gasification reactor; a first flange extending radially outwardly from said body and a second flange extending radially outwardly from said nozzle; at least one attachment component for removably securing said first flange and said second flange to one another such that said nozzle inlet is in fluid flow communication with said body outlet when said nozzle is attached to said body; a first o-ring and a second o-ring for providing a substantially airtight junction between the first flange and the second flange when said flanges are removably secured to one another, wherein said airtight junction is suitable for use at the pressures and temperatures typically associated with the gasification of a carbonaceous feedstock without substantial leakage of the junction; a second stage reactor section positioned generally above said first stage reactor section and defining a second reaction zone.
