RTO with Zero Fuel Use

In Uncategorized by airclear

Air Clear engineers designed, fabricated and installed a two-chamber RTO with a hot bypass system, counter flow air-to-air heat exchangers, and an ambient air dilution valve.  The emission requirements were successfully met; exceeding 98% DRE (Destruction and Removal Efficiency) while producing approximately 7,900 SCFM of 375-400°F pre-heated ambient air for the drying/curing oven. The DRE (Destruction and Removal Efficiency) is monitored by two FID monitors placed at the inlet and outlet of the RTO. The LEL (Lower Explosive Limit) is also monitored on the outlet of the drying/curing oven. The heat exchanger operates with greater than 68% effectiveness.  Once in operation, the RTO operated with zero fuel input while providing the required hot air to the drying/curing oven.  Organic concentrations above 8% were sufficient to maintain the required combustion chamber temperature. The system is a two chamber design, with poppet valves fabricated and tuned by Air Clear.  This feature allows Air-Clear to meet greater than ≥98% (Destruction and Removal Efficiency).  The entire system was designed, fabricated and installed by Air Clear LLC located in Elkton Maryland. The system was installed in three weeks and was operational with the coating line operations within 36 hours of initial start-up. A PLC system was used to provide flexible, easy, remote operation of the RTO as well as the existing drying/curing oven as a complete system.  In addition, Air Clear included features which allow Air Clear engineers to monitor and troubleshoot the system operation from anywhere in the World.  This dramatically improves on-line productivity. https://www.airclear.net/silicone-teflon-coating-operation/
