Download or read book Development of Advanced NO Sub X Control Concepts for Coal-fired Utility Boilers written by and published by . This book was released on 1991 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hybrid technologies for reduction of NO(subscript x) emissions from coal fired utility boilers may offer greater levels of NO(subscript x) control than the sum of the individual technologies, leading to more cost effective emissions control strategies. Energy and Environmental Research Corporation had developed a hybrid NO(subscript x) control strategy involving two proprietary concepts which has the potential to meet the US Department of Energy's goal at a significant reduction in cost compared to existing technology. The process has been named CombiNO(subscript x). CombiNO(subscript x) is the integration of three separate NO control technologies: (1) Gas Reburning, (2) CO-Promoted Selective Non-Catalytic Reduction, and (3) Methanol Injection/NO2 Scrubbing.
