Abstract

PURPOSE: To secure high denitration ratio at relatively low temperature and at various oxygen content by controlling the temperature and mol ratio of hydrazine to be added, which are most suited for the reduction of NO, in proportion to the oxygen concentration of exhaust combustion gas containing NOx.
