Carbon black reactor with angled combustion chamber and non-aligned tangential hot gas entries for production of negative tint residual carbon black

A carbon black reactor to produce non-uniform gas flow patterns utilizes (a) a precombustion chamber skewed at an angle of 30-60 degrees from the reactor axis with (1) offset tangential hot gas entries, (2) axial or offset multiple oil feed entries, (b) an optional venturi which can be offset from the reactor axis and/or asymmetric in form.
