摘要

This paper describes the successful design, installation and operation of Canada's first Selective Catalytic Reduction (SCR) systems for nitrogen oxides (NO{sub}x) reduction installed at Ontario Power Generation's (OPG's) Lambton and Nanticoke coal fired power stations. OPG's initiative to reduce the emissions of NO{sub}x (which contribute to the formation of smog) from their coal fired stations led to the award of a contract to Babcock & Wilcox Canada (BWC) in June 2001 for the turnkey supply of SCRs for Lambton units 3 & 4 and Nanticoke units 7 & 8. B&W's scope included design, supply, construction and start-up of the SCRs, anhydrous ammonia systems, SCR support steel, pressure part modifications, platework modifications and reinforcement, control components and induced draft (ID) fan upgrades. A split economizer design was used to provide the optimum SCR inlet gas temperature while still maintaining boiler efficiency across the unit load range. The SCRs are designed for an outlet NO{sub}x level not to exceed 0.0344 kg/10{sup}6 kJ (0.08 lb/10{sup}6Btu) with a maximum of 2 ppm ammonia slip during normal unit operation. This equates to a combined NO{sub}x removal efficiency of 83.1% or approximately 22,000 Tonnes/year of NO{sub}x removal. This is equivalent to taking 733,000 cars off the road. All units have completed acceptance tests and are in commercial operation.

B＆W的范围包括SCR的设计，供应，施工和启动，无水氨系统，SCR支持钢，压力部件修改，板块改造和加固，控制组件和诱导草稿（ID）粉丝升级。分流节能器设计用于提供最佳的SCR入口气体温度，同时仍然保持锅炉效率在单元负载范围内。 SCR设计用于不超过0.0344 kg / 10 {sup} 6kj（0.08磅/ 10×sup} 6btu）的出口No {sub} x级，在正常单元操作期间最多2ppm氨滑动。这相当于83.1％或大约22,000吨/未{sub} x去除的组合的No {sub} x去除效率。这相当于在路上服用733,000辆汽车。所有单位都完成了验收测试，并在商业运营中。
