ABSTRACT:
A coal and char burner (10) is formed of three concentric cylinders (14,16,18). The central passage (32) conveys char particles into the interior (20) of a coal gasifier. Fresh coal and secondary air enter the gasifier through concentric passageways (24,27) surrounding the central passageway (32). The coal and air form a high temperature reaction envelope (30) which surrounds the char stream (22) and rapidly heats the char particles.
