摘要
针对生物质锅炉环保验收过程中颗粒物排放总量超出环评报告预测总量的问题,分析了烟气量、氧含量、烟气温度等指标的异常情况,研究了颗粒物总量超标原因。结果表明:该除尘系统设计风量过大,燃料不充分燃烧,氧含量及烟气量过大,烟气温度偏高。建议优化设计、调整风速、规范数据分析并加强技术咨询。
In view of the issue that the total particulate matter emission during the environmental protection acceptance of a biomass boiler exceeded the amount predicted in the environmental impact assessment(EIA)report,the abnorma lindicators such as the flue gas volume,oxygen content,and flue gas temperature were analyzed,as well as the reason why the particulate matter emission exceeding the standards.The results show that over-standard particulate matter emission is caused by excessive design air volume of the dust removal system,imcomplete combustion of fuel,excessive content of oxygen and flue gas,and too high flue gas temperature.It is recommended to optimize design,adjust wind speed,standardize data analysis and strengthen technical consultation.
