摘要
Abstract
The horizontal single foot furnace combustion test system was employed to carry out emission characteristics study on combustion and co-combustion of biomass and anthracite.The effect of furnace temperature and mixing ratio on emissions characteristics was investigated.The results show that:the wood had the fastest burning rate,its peak flame temperature moved in advance;increasing the sawdust proportion can promote ignition of the mixture but reduce the overall combustion temperature;when the excess air coefficient decreased from 1.2 to 0.9,the overall combustion temperature increased and the flame temperature zone moved in advance.The flammability of the mixed fuel enhanced,which reduced the CO content during combustion;addition of the sawdust enhanced the combustion,consumed a large amount of oxygen,thus to form a weak reducing atmosphere to help reduce the formation of NOx.关键词
