Abstract:

A torch cutting and fume collecting enclosure is disclosed that is particularly adapted for the collection of lead-containing fumes and gases emitted during cutting of steel strands. The enclosure comprises a plurality of walls and two flexible barriers disposed on opposite ends of the enclosure, one at a receiving end, and the other at an output end of the enclosure. The enclosure further comprises a unique air handling system comprising one or more collector hoods, ducts and plenums for collecting and moving air and other gas flows from the enclosure for subsequent treatment and/or discharge. The air handling system utilizes a unique tapered configuration for one or more plenums that reduces the tendency for particulates to separate from an air or gas flow.

Abstract:

A metallurgical vessel cover having integral fume collection provisions is disclosed. The cover features a plurality of inlet openings defined about the perimeter of the cover that direct fumes or other gases residing around the exterior of the cover, through the interior of the cover, and to a single collection region. There, the fumes or gases are discharged through a shroud, which preferably is connected to an attachable venting duct. The cover also features an internal configuration for reducing heat transfer through the cover.
