RTO (Regenerative Thermal Oxidizer) Systems in Conjunction with MHFs

RTO (Regenerative Thermal Oxidizer) systems are being introduced at MHF sites to reduce heavy slag and temperatures. They help address EPA regulatory issues without losing valuable hearth capacity with a Zero Hearth. RTO systems can help to reduce emissions, including CO and NOx. Some systems have been guaranteed to reduce CO emissions emanating from Buyer's process by more than 95%.

Attached is a paper by Stan Chilson, PE and Senior Project Manager from GHD. The paper titled, "Two-Stage Thermal oxidization: A Cost-Effective, Environmentally Sound Alternative for BioEnergy Recovery from Multiple Hearth Furnaces" discusses energy recovery using a thermal oxidization system with a Multiple Hearth Furnace (MHF) at a plant in Pennsylvania.
