✦ Synopsis
The design, construction and testing of a low nitrogen oxide (NO V ), staged combustor to burn low calori"c value gas derived from agricultural wastes is described in this paper. A cyclone combustor was used as the "rst stage combustor. Nitrogen oxide emissions during combustion of low calori"c value gas derived from gasi"cation of cotton gin trash were reduced from 1400 ng/J without staged combustion to less than 100 ng/J with staged combustion. An equivalence ratio in the "rst stage between 1)4 and 1)8 for the stoichiometric mass of air to actual mass of air, and a minimum delay time between stages of 0)2 s were found to be su$cient to achieve NO V emissions below the Environmental Protection Agency limit of 260 ng/J.
