介绍了一种通过新型燃烧控制系统和传感器组件来解决提高锅炉效率和减少排放问题的经济有效的解决方案，适用于热水或蒸汽发电厂，且容量大于10 MMbtu/h。该系统持续监测烟气排放，并通过调节燃烧器的入口燃料阀和空气挡板来减少排放。新的燃烧器管理系统采用了一种新的控制算法、用于监测废气成分的低成本传感器，以及一种用于锅炉性能可视化的用户友好工具。控制器持续保持向燃烧器提供燃料和空气的最佳比例，以减少因空气含量过高而导致的效率低下，同时防止因不完全燃烧而导致的不安全操作。这一新系统是商用“氧气调节”解决方案的一种改进，与传统系统形成对比，传统系统具有预设的机械连杆，以固定燃油与空气的比率。 新的控制算法考虑了环境条件的变化，例如进气温度和湿度，以及系统退化，例如连杆位置漂移。预计使用这种反馈控制系统可使年平均效率提高约5%。因此，每年可以节省大量燃油，以支付与新系统相关的成本。将介绍新的系统设计和在位于纽约州沃特夫利特的美国陆军沃特夫利特兵工厂演示该系统期间获得的数据。引用:ASHRAE Trans。，第118卷第。德克萨斯州圣安东尼奥2号

A cost effective solution to the problem of improving boiler efficiency and reducing emissions by means of a novel combustion control system and asensor package is described, with applications for hot water or steam generation plants and capacity larger than 10 MMbtu/h. The systemcontinuously monitors flue gas emissions and reduces them by means of regulation of the burner's inlet fuel valve and air damper. The new burnermanagement system incorporates a novel control algorithm, low cost sensors to monitor exhaust composition, and a user friendly tool forvisualization of boiler performance. The controller continuously maintains the optimum proportion of fuel and air feeding the burner in order toreduce inefficiencies arising from excess air content while preventing unsafe operation arising from incomplete combustion. This new system is anevolution of commercially available "O2 trim" solutions and contrasts with legacy systems with preset mechanical linkage to fix the ratio of fuel toair. The new control algorithm accounts for variation of environmental conditions, e.g., inlet air temperature and humidity, and systemdegradation, e.g., linkage position drift. Use of this feedback control system is anticipated to enable increases in year averaged efficienciesapproximately 5%. Hence, significant annual fuel savings can be expected to defray costs related to the new system. The new system design anddata obtained during a demonstration of the system at the US Army's Watervliet Arsenal in Watervliet, NY will be presented.
