ALZETA CSB Low NOx Burner Reduces NOx Emissions Below 9 ppm

SANTA CLARA, CA ( October 27, 1999 ) ALZETA today announced the successful installation, commissioning and source testing of its PYROMAT CSB™ burner in a 50,000 lb/hr package boiler at the Cribari Winery in Fresno, California. Winery operators at Cribari were faced with the need for increased capacity, ongoing maintenance and inefficient operations from old style brick-set boilers, AND the requirement to satisfy tough new environmental standards.

This installation, completed in cooperation with Nationwide Boiler of Fremont, California, was designed to comply with the most recent changes in the emissions regulations from the San Joaquin Valley Unified Air Pollution Control District - rules requiring less than 9ppm NOx emissions. Achieving this goal could not be done however at the expense of compromising operational efficiency or adding to the challenges of steam plant operations. The Nationwide/ALZETA packaged solution achieved this and more.

Timely installation and commissioning of the boiler were key factors in the delivery of this unit, since it needed to be fully operational in time for the fall harvest. Despite challenges in placing the 60,000 lbs. boiler into the boiler room by a careful lift through the winery roof, the boiler was easily integrated with the existing steam plant. What's more, field start up of the burner took less than one day, perhaps an new record for an ultra-low NOx boiler/burner package. And, when the unit was tested for permit compliance, the burner system clocked in well below the 9ppm required.

ALZETA offers its PYROMAT CSB™ for commercial and industrial boilers new and retrofit applications. These burners are offered in both <9 and <20 ppm versions to balance the needs of emissions regulations. Units ranging from 2 MMBtu/hr commercial to 125 MMBtu/hr industrial boilers have demonstrated robust performance for as many as 5 years, convincing even the most demanding customers that environmental compliance does not need to come at the expense of steam plant reliability.
