Process and apparatus for burning hydrogen sulfide and other combustible fluid to recover sulfur

Apparatus for burning a first hydrogen sulfide fluid stream and a second organic sulfur fluid stream into a product suitable for recovery of free sulfur therefrom, comprising:

• (a) a reactor housing means comprising an internally insulated cylindrical chamber of substantially constant diameter having an annular wall partially closing an inlet end, and an outlet end, a selected portion of the interior space downstream of said inlet end defining a combustion section, and the remaining portion downstream thereof of said chamber defining a reaction section;
• (b) first burner means positioned axially through a central opening at said inlet end, providing an annular space between said first burner means and said central opening, and means to pass a selected smaller portion of said first hydrogen sulfide stream through said first burner means;
• (c) a second burner means positioned in the said annular space and means to supply all of said second fluid stream through said second burner means;
• (d) air inlet and plenum means for providing combustion air through said annular space;
• and
• (e) plural injection means to the interior of said reactor at about the downstream junction between said combustion space and said reaction space, said injection means spaced circumferentially about said housing, and means for injecting the remaining portion of said first hydrogen sulfide stream through said injection means.
