秸秆直燃锅炉的料仓防爆对策

Prevention Measures for Deflagration of Straw Direct Combustion Boiler Silo

生物质发电企业的秸秆直燃锅炉料仓发生粉尘爆燃事件会导致人员伤亡和设备损坏。为了有效地降低料仓爆燃事件的发生几率,对该锅炉燃料特性、料仓结构及锅炉运行情况进行了详细的分析。介绍了通过在下料管加装防正压回火的挡板锁气器、在料仓加装布袋除尘器等设备改造,将导致料仓爆燃的主要要素进行针对性的控制的措施。

Biomass power generation business straw direct combustion boiler silos has a risk of dust deflagration,which results in casualties and equipment damage.In order to avoid the silo deflagration efficiently,a detailed analysis of boiler fuel characteristics,silo structure and the boiler operation was carried out.The feeding pipe to install anti-lock air pressure tempered baffle device,the silo bag house filters and other equipment installed transformation,coupled with a positive run adjustment will lead to deflagration of the main elements of silos targeted control,after a period of time to run validation,achieving notable results.
