01 December 2004 ALSTOM coal-fired boilers lead acid rain program in low NOx emissions for fourth straight year
24 of the 25 lowest emitting pulverized coal units without post-combustion equipment use ALSTOM-supplied low NOx firing systems
For the fourth year in a row, ALSTOM-supplied boilers have earned top ranking among coal-fired units as the US’s lowest emitters of nitrogen oxide (NOx), according to the latest US Environmental Protection Agency (EPA) data on power plant NOx emissions. The new EPA data cover power plants in the Acid Rain Program for the year 2003.
All 24 ALSTOM units are tangentially fired boilers retrofitted with low NOx firing systems that burn Powder River Basin (PRB) coals. The EPA findings, ALSTOM said, demonstrate that tangentially fired units equipped with its low NOx firing systems and burning PRB coals can achieve industry-leading NOx emissions. All 25 boilers in this ranking were also originally supplied by ALSTOM.
“Our customers depend on us to deliver boiler solutions with maximum value, and EPA’s scorecard proves that we do,” said Jeff Sizer, ALSTOM’s general manager of Performance Projects Worldwide. “For all four years that Acid Rain Program statistics have been available, ALSTOM clean coal technologies clearly lead the US power industry. Our low NOx firing systems are widely acknowledged as the benchmark for all other in-furnace technologies,” Mr Sizer added.
Reducing NOx emissions can help to lower ozone levels and improve air quality. Developed specifically for tangentially fired boilers, ALSTOM’s Low NOx Concentric Firing System (LNCFS)™ and TFS 2000R™ low NOx systems have consistently achieved the industry’s lowest NOx emissions, particularly when burning PRB coals. PRB coals are a plentiful domestic (US) energy source.
