氨水直喷技术在燃机余热锅炉脱硝工程上的应用

Application of aqueous ammonia spraying technology for denification project in waste heat boiler ofcombined cycle units

介绍了在燃机出口烟道直接喷入氨水进行SCR烟气脱硝技术。氨水喷入采用自调节式喷枪,均匀布置在燃机出口烟道圆周,具有系统简单、占地小、投资和运行成本低、调节灵活、负荷适应性强和可实现在线维护等特点,为同类机组设计和运行提供参考。

A technology of SCR flue gas denitrification by injecting aqueous ammonia directly into the gas outlet flue is introduced.Self-adjusting spray gun is used for aqueous ammonia injection,which is evenly arranged around the outlet flue of the gas turbine.It features simple system,small land occupation,low investment and operation cost,flexible adjustment,strong load adaptability and on-line maintenance.It provides a reference for the design and operation of similar units.
