Advanced instrumentation for the B&W low emission boiler
- PSI Environmental Instruments Corp., Andover, MA (United States)
The next generation of coal-fired boilers targeted for both the domestic and overseas markets must meet and maintain very low emission levels in order to be competitive. Cost of electricity and generation cycle efficiency will also be market drivers. To meet this challenge and to maximize the use of tried and true coal-fired steam cycle technology, Babcock & Wilcox (B&W) and the U.S. Department of Energy are partnering to demonstrate break-through emission control technologies capable of less than 0.1 lb NO{sub x}/MBtu fired (without the added financial burden of backend NO{sub x} cleanup). The key to the B&W approach is the use of advanced diagnostics to measure and control key process parameters during deeply staged combustion. Per burner air/fuel ratio control is achieved by advanced processing of flame scanner signals combined with an advanced burner design. The resulting computer-controlled system is analogous to automobile engine diagnostic systems introduced in recent years. This paper will cover the conceptual design and preliminary tests of LEBS NO{sub x} control diagnostics components in test facilities and existing boilers. Implications of the preliminary results on future testing and commercial designs will also be discussed.
