Bench-scale studies to identify process parameters controlling reburning with pulverized coal. Project summary

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: (1) combustion modification (controls flame temperature and maximizes fuel-rich residence time to minimize NOx formation); and (2) flue gas cleaning (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.
