Title:
CONSTANT PROCESS EXHAUST SYSTEM
Document Type and Number:
WIPO Patent Application WO/2005/107923
Kind Code:
A1
Abstract:
A process exhaust system (10) includes a closed loop control system adapted to hold constant an exhaust air volumetric flow rate by automatically compensating for increases and decreases in a functional resistance in an exhaust airflow of the process exhaust system. The closed loop control system includes a volumetric flow sensing system (40) which is resistant to degradation over time when the degradation is at least partially caused by accumulation of any process-generated contaminating byproduct.
