Show Equipment (CPE) of Modesto, California, and Alzeta Corporation. C P E is the Northern California manufacturer's representative for the Alzeta CSB. NOx emissions, as recorded using a portable emissions analyzer were 8 ppmvd (corrected to 3 percent 02) at high fire, with sub-9 ppm emissions recorded from a minimum fired duty of 18.7 MMBtu/hr up to high fire. C O emissions were 5 ppm or lower over the full range of operation. The boiler was put into continuous operation on July 28. The third party source test was completed on September 28, 1999. Although the test results are not yet available, Alzeta, C P E and NBI personnel were on site to witness the test. NOx emissions were consistent with the earlier portable emissions analyzer results, and were shown to be below 9 ppm, with C O emissions under 50 ppm. As part of current San Joaquin Valley Unified A P C D guidelines, emissions from this boiler will be monitored monthly to demonstrate compliance with the 9 ppm guarantee. 4. SUMMARY Installation of an Alzeta CSB low NOx burner with a 9 ppm NOx guarantee was completed this year at the Cribari Winery in Fresno, California, and is documented in this report. The burner met emissions requirements for N O x and CO, and in addition provided the following benefits to the customer: • Standard single-point control of gas and air was used to achieve 9 ppmvd N O x emissions and sub-50 ppmvd C O emissions. This approach minimizes control system costs to the end user • The CSB has demonstrated the ability to change load rapidly, even at the 9 ppm N O x level, without encountering combustion instabilities or noise. Load changes from minimum to maximum fire in 30 seconds to 1 minute are typical • Burner startup at the Cribari Winery was completed in one day, minimizing startup costs 6 |
