本技巧提供了有关氮氧化物（NOx）形成和控制技术的基本信息。多年来，人们对燃用生物质衍生燃料（生猪燃料、树皮、木屑、锯屑、砂纸粉尘、铁路枕木、纸浆厂澄清污泥、建筑和拆除垃圾以及红色和黑色制浆液）的工业锅炉应用NOx法规的兴趣有限，一些州的监管机构正在制定锅炉NOx排放限制，其严格程度足以影响锅炉运行。需要就燃料使用、运行参数、NOx控制技术的实施以及对其他污染物产生的影响做出明智的决定。本技巧提供了背景信息，以帮助工程师、操作人员和管理人员了解可用于满足法规遵从性要求的问题和选项。

This TIP provides basic information on nitrogen oxide (NOx) formation and control technologies. After years of limited interest in applying NOxregulations on industrial boilers that fire biomass derived fuel (hog fuel, bark, wood chips, saw dust, sander dust, railroad ties, pulp mill clarifier sludges, construction and demolition debris, and red and black pulping liquors), regulators in some states are establishing NOxemissions limits on boilers that are strict enough to impact boiler operations. Informed decisions on fuel usage, operating parameters, NOxcontrol technology implementation, and impact on other pollutant generation will be needed. This TIP offers background information to help engineers, operating staff, and managers understand the issues and the options that are available to meet compliance requirements.
