Abstract A fume incinerator for afterburning fumes containing air polluting elements includes a casing having a burner disposed in a combustion chamber. The casing includes an outer compartment which is sealed from the combustion chamber and provides a dead air space between the combustion chamber and the outer walls of the casing. A blower receiving fumes from an industrial process or apparatus directs the fumes into the combustion chamber. A conduit in communication with the dead air chamber is in communication with the suction conduit of the blower so that any fumes which may leak into the dead air space or chamber are immediately removed and returned into the combustion chamber, thus preventing leakage of the same through the outer walls of the casing and into the atmosphere.
The invention in accordance with claim 1, said outer wall structure comprising laterally spaced vertical walls including heat insulating means therebetween, and said second conduit extending through said outer wall structure and communicating with said combustion chamber.
Claim 2
Dependent Claim
38 words
The invention in accordance with claim 1, said combustion chamber including a cylindrical vertical baffle means spaced inwardly relative to said inner wall structure to guide said incoming fumes in maze-like fashion into proximity of said burner unit.
Claim 3
Dependent Claim
50 words
The invention in accordance with claim 3, including a tubular element concentric with said baffle and laterally spaced with respect thereto having an upper open end communicating with said stack and a lower open end disposed adjacent to and above said burner unit, and valve means in said third conduit.
