Research on Low Nitrogen Combustion Transformation Technology and Application Effect of Chain Boiler
Taking a 70MW chain hot water boiler in a thermal power company in Xinjiang as an example,the problems existing in the original low nitrogen combustion system are analyzed,the low nitrogen combustion retrofit technology for chain grate boiler is studied from three aspects:boiler air chamber,flue gas recirculation system and secondary air system.After transformation,the low-nitrogen combustion system of the chain boiler has an obvious denitrification effect,reduces the production of nitrogen oxide from the source,and obtains good economic benefits,the realization of energy saving and emission reduction provides a feasible and reliable technical reference and process reference.
