The report addresses the evaluation of a technology which is a combination of two technologies used to control the atmospheric emission of NOx by stationary sources: combustion modification, which controls flame temperature and maximizes fuel-rich residence time to minimize NOx formation and flue gas cleaning, which uses a reducing agent with or without a catalyst to remove NOx from combustion products. The combined technology uses fuel as a reducing agent to remove NOx. The process, referred to as in-furnace NOx reduction, reburning, and staged fuel injection, can be applied to many types of combustion systems. In fact, reburning is the process which allows the 'in-furnace NOx reduction' to take place. Reburning involves two processes: NO reduction, in which reburning fuel is added to the combustion products of the main combustion zone, which operates fuel lean, to produce a fuel-rich mixture, products of which are referred to as total fixed nitrogen, and TFN oxidation, in which air is added to produce overall fuel-lean conditions, with the NH3, HCN, NO, and char nitrogen converted to either N2 or NO and fuel oxidation completed.
