Catalytica Combustion Systems, Inc., Xonon™ Cool Combustion
Nitrogen oxides (NOx) air pollution control technologies (APCTs) are among the technologies evaluated by the APCT Environmental Technology Verification (ETV) Program. The APCT program developed the Generic Verification Protocol for NOx Control Technologies for Stationary Combustion Sources to provide guidance on the verification of specific technologies. The critical performance factor for this verification is the NOx emission concentration within the performance envelope of the test. This protocol was developed by RTI and MRI, reviewed and discussed by a technical panel of experts, and approved by EPA. The protocol states the critical data quality objectives for a NOx control technology verification, as well as noncritical but still important measurements of other performance parameters. The Catalytica Combustion Systems, Inc., Xonon™ flameless combustion system was submitted to the APCT ETV program for verification. A test/quality assurance (QA) plan, prepared in accordance with the generic verification protocol, addressed the site specific issues associated with the verification test. The verification was conducted the week of July 17, 2000, at the Xonon™ installation on a 1.5-MW gas turbine in Santa Clara, CA. The mean outlet NOx concentration during the verification was determined to be 1.13 ppmvd at 15% O2. The measured NOx concentration was well within the stated data quality objective for the NOx measurement. Other important performance and operating parameters were also measured.
