In 1988, the South Coast Air Quality Management District in California (SCAQMD) tightened its grip on industrial emissions of nitrogen oxides (NOx). The new statute, Rule 1146, mandates a 75% reduction in NOx emissions over a five-year period ending this July. Anheuser-Busch Inc.'s second-largest brewery in Van Nuys fell under the new law's jurisdiction. Under the new law, the maximum allowable NOx emission must be reduced from 120 to 30 ppm for the two largest boilers. There were two alternatives: either prevent its formation inside the boiler, or remove it from the off-gases via selective catalytic reduction (SCR) or selective non-catalytic reduction (SNCR). Prevention was chosen, because the NOx-removal technologies are unproven in the US on natural-gas-fired boilers. In addition, it was not known whether SCR or SNCR could respond to the wide swings in boiler demand. At any given time, loads between 30 and 100% of capacity would be required from the boilers. The brewery retrofitted the 125,000-lb/h boilers with Variflame burners, based upon an earlier retrofit at Anheuser-Busch's Merrimack, N.H., brewery. The paper describes this burner and its performance.
