CLOSED CAPTURE EMISSION SYSTEM

摘要

An apparatus and method for capturing the emissions from a controlled atmosphere treatment apparatus of the type having at least one, and usually several, controlled atmosphere zones therein and exhaust stacks that deliver environmentally unfriendly emissions therefrom. Nozzles are attached to the exhaust stacks from the various controlled atmosphere zones in the treatment apparatus. The nozzles accelerate the exhaust flow from the exhaust stacks, provide a means for measuring the flow from the exhaust stacks, yet maintain the mass flow rates from the exhaust stacks at predetermined levels. The flow from the nozzles is directed through closed conduits to an optional filter and an exhaust fan that provides suction to draw the exhaust flow through the nozzles.
