The investigation was examined into restraint of nitrogen oxides in exhaust gas bychanging the combustion conditions as to municipal solid waste incinerators. The relations between nitrogen oxides in exhaust gas and combustion conditions ofmunicipal solid waste were investigated. It is confirmed that nitrogen oxides inexhaust gas have positive relation to the combustion temperatures and the concentrations of oxygen in exhaust gas. Hence relatively low combustion temperatureand low oxygen may suppress nitrogen oxide emission. But the concentrations of oxygen must be maintained with considerations of carbon monoxide and the soot and dust emissions because emissions of carbon monoxide and the soot and dust werencreased with the combustion under low oxygen atmosphere.
