CPC classification number: F23G7/05 , F23G5/008 , F23G7/14 , F23G2205/12 , F23G2206/10 , F23G2206/203 , F23G2207/101 , F23N2041/18
Abstract: A toxic waste incinerator is capable of enhanced combustion of hazardous waste (oil contaminated sand, human waste, garbage, etc.) utilizing immersed non-combustible and thermally conductive objects for increasing heat feedback from the flames to the unburned fuel, while air inlets are used to optimize the air entrainment rate to enhance the burning efficiency. The burning rate of a fluidic mass such as a sand-oil mixture is enhanced using immersed conductive objects (copper rods) which enable rapid heat-up of the flame exposed to the upper surface of the rod and transmits heat back into the sand. Consequent conduction of heat to the porous media through the lower portion of the immersed rod significantly increases vaporization and therefore the burning rate. Incineration may be performed on a transient, exigent basis as with hazardous waste and oil spills, or as part of a permanent fixture for receiving an ongoing waste stream.
