RESEARCH ON THE COMBUSTION EMISSIONS OF NO AND CO FROM BIOMASS SOLID FUEL

The gaseous emission of solid biomass briquette in the process of combustion in domestic has not been analyzed clear， and the effect of the feed rate and intake air on gaseous emissions and other issues of biomass fuel combustion test have been under-researched． The paper used Testo350 flue gas analyzer equipment to test the gaseous emissions of wood，cotton stalk and cornstalk in the process of combustion， and focused on the NO and CO emissions of three kinds of biomass briquette under different feeding quantity of intake air and under different circumstances． The results showed that，NO emissions of three kinds of biomass fuel was less than 0. 05%，the amount of CO was less than 1%． The amount of NO and CO emissions increased with the increase of the feed rate． The content of the gaseous emissions reduce when the intake air increased． The research could be used to guide the actual operation of the boiler fuel and provide a reference for optimizing the combustion and emissions biomass modeling fuel．
