循环流化床锅炉NOx排放浓度调整方法探讨
摘要
针对广州石化公司循环流化床锅炉(CFB)NOx排放浓度偏高的问题
分析认为主要是全烧焦工况下炉膛温度偏高
SO2和NOx控制采取的措施与结果相互矛盾等所致。对此
提出了锅炉定期掺煤、控制氧量、调整2台锅炉负荷等运行措施。实施后
CFB机组NOx排放量稳步下降至200mg/m3以下
实现了NOx、SO2、烟尘3大环保指标全部稳定达标。
Abstract
Directing against the problem of high concentration of NOx emitted from CFB boiler in Guangzhou Petro-chemical Branch Company
it is believed that the main causes are:the high temperature in furnace under condition of fully burning cokes
as well as mutual contradiction in SO2 and NOx control etc..For these
several measures
such as periodically coal-blending for the boilers
controlling the oxygen quantity
and adjusting the load of two boilers etc.
have been put forward.After implementation
NOx emission from CFB boilers has steadily reduced
