Waste material incineration system and method

摘要

A waste material incineration system (10) and method of combusting waste material is provided wherein system (10) includes a longitudinally directed furnace (14) having a first combustion zone (42) and a second combustion zone (44). Waste material or other fuel is inserted into furnace (14) through a furnace inlet (26) and passes by gravity assist into a vortexing pattern dependent upon the geometrical contouring of the internal walls of furnace (14) in combination with preheating air conduits (86, 88 and 90). Subsequent to vortexing in the first combusion zone (42), the substantially fully combusted gases are transported through second combustion zone (44) for insert into a heat exchanger unit (12) and then passes to a scrubber unit (34) where the exhausted gases are further cleansed to expulsion of the cleansed exhaust gases through an exhaust stack (16) to the ambient atmosphere.
