Method 301 evaluation of a technique for collection and measurement of ammonia in stationary source emissions

摘要

Injection of ammonia or urea to the combustion zone of a boiler reduces the formation (and thus emissions) of oxides of nitrogen. Under certain conditions a protion of the ammonia may "slip" and be emitted to the atmosphere. State air quality organizations have expressed interest in monitoring this and other sources of ammonia. Users of the injection technology need emission data to assist in process optimization. In response to these meeds, the Environmental Protection Agency supported labroatory development and field testing of an EPA Method 17-based procedure for quantitating ammonia at stationary sources.
