Technical Bulletin No. 0107: A Study of Nitrogen Oxides Emissions from Lime Kilns (AQTB)

This technical bulletin reports on the findings of the first phase of a study of nitrogen oxide emissions from lime kilns. The nitrogen oxide emission rates observed for lime kilns were highly variable and at one gas-fired kiln were found to be related to combustion zone temperature. Combustion zone temperature was measured at only one test site. In this case combustion zone temperatures of about 1850 degrees C were required for minimum nitrogen oxide emissions.
