Stationary source emissions - Determination of low range mass concentration of dust - Part 1: Manual gravimetric method

被代替

适用范围: This European Standard specifies the standard reference method (SRM) for the measurement of low dust concentration in ducted gaseous streams in the concentrations below 50 mg/m? at standard conditions. This European Standard is primarily developed and validated for gaseous streams emitted by waste incinerators. More generally, it can be applied to gases emitted from stationary sources, and to higher concentrations. If the gases contain unstable, reactive or semi-volatile substances, the measurement depends on the sampling and filter treatment conditions. This method has been validated in field tests with special emphasis to dust concentrations around 5 mg/m?. The results of the field tests are presented in Annex A.

术语	描述
粉尘颗粒 dust particles	在采样点条件下分散在气相中的任何形状、结构或密度的颗粒，可以在特定条件下通过过滤收集
过滤温度 filtration temperature	采样气体在过滤器下游的温度
管道内过滤 in-stack filtration	在管道内进行过滤，过滤器位于采样喷嘴下游的过滤器壳体中
管道外过滤 out-stack filtration	在管道外进行过滤，过滤器位于采样喷嘴和吸入管（采样探头）下游的加热过滤器壳体中
等速采样 isokinetic sampling	采样流速使得气体进入采样喷嘴的速度和方向与管道中测量点的气体相同

采样系统	主要包括过滤装置（过滤器壳体和过滤器）、入口喷嘴、吸入管（用于管道外过滤装置）、气体泵、气体计量装置（包括冷却和干燥系统以及控制等速采样条件的系统）
