Emission Control of NO and for the High-Temperature and Low Concentration Combustion of Coke by Urea and
Publication: Journal of Environmental Engineering
Volume 131, Issue 2
Abstract
Urea and were used to control the emission of NO and from the combustion of coke at high-temperature and low oxygen concentration. Urea and could control NO emission only under . Their effects disappeared above even though the increase of urea and content from . However, they showed good desulfurization effect on the emission of at all combustion temperatures and their effects showed remarkable results even at . Only of urea or could control the emission of effectively at 1400 and . This effect was caused by ∙NH and from the thermal decomposition of reducing agents at high temperature. Low concentration showed little effect on the removal of . Ammonia slip from the thermal decomposition of reducing chemical was not a considerable level.
