NO Sub (X) Formation from Different Coal Types in a Bench Scale Reactor under Excess Air and Staged Combustion Conditions. Final Report

摘要

This report describes the results from the bench-scale fuel screening experiments. Twenty non-US coals (including lignite, subbituminous and bituminous) were tested in a 21-kw sub (t) refractory-lined tunnel furnace. NO emissions were measured as a function of coal composition and initial fuel/air contacting rate under excess air conditions. In addition, in-flame measurements were made to quantify the influence of stoichiometry and temperature on the fate of fuel nitrogen species under staged combustion conditions.
