固定源排放 - 氨的质量浓度的测定 - 手工方法

[中文适用范围]： 本文件规定了测定工业工厂（例如燃烧工厂或农业工厂）废气中氨（NH3）质量浓度的手动测量方法，包括采样和不同的分析方法。 通过该方法测量在采样温度下具有挥发性并在吸收溶液中采样时解离产生铵离子的所有化合物，从而给出废气中的挥发性氨含量。 本文件规定了一种独立的测量方法，该方法已在标准条件下 NH3 浓度范围约为 8 mg/m3 至 65 mg/m3 的现场测试中得到验证。 验证范围的下限是在测试工厂的操作条件下确定的。 测量方法可以使用较低的值，具体取决于例如采样持续时间、采样体积和所使用的分析方法的检测限。 注 1：附件 A 给出了工厂、现场测试条件和现场获得的性能特征。 这种测量方法可用于氨排放的间歇监测以及永久安装的自动化氨的校准和验证。 测量系统。 注 2：EN 14181 中一种独立的测量方法称为标准参考方法（SRM）。 [外文原描述]： This document specifies a manual method of measurement including sampling and different analytical methods for the determination of the mass concentration of ammonia (NH 3 ) in the waste gas of industrial plants, for example combustion plants or agricultural plants. All compounds which are volatile at the sampling temperature and produce ammonium ions upon dissociation during sampling in the absorption solution are measured by this method, which gives the volatile ammonia content of the waste gas. This document specifies an independent method of measurement, which has been validated in field tests in a NH 3 concentration range of approximately 8 mg/m 3 to 65 mg/m 3 at standard conditions. The lower limit of the validation range was determined under operational conditions of a test plant. The measurement method can be used at lower values depending, for example, on the sampling duration, sampling volume and the limit of detection of the analytical method used. NOTE 1 The plant, the conditions during field tests and the performance characteristics obtained in the field are given in Annex A. This method of measurement can be used for intermittent monitoring of ammonia emissions as well as for the calibration and validation of permanently installed automated ammonia measuring systems. NOTE 2 An independent method of measurement is called standard reference method (SRM) in EN 14181.
