T/XZFW 004-2023 The determination of low-concentration particulate matter from fixed pollution sources using beta radiation method

Scope

Main technical content: 1. Scope This document specifies the method for determining the concentration of low-concentration particulate matter in the exhaust gas of fixed pollution sources. This document is applicable to various types of coal-fired, oil-fired, and gas-fired boilers, industrial furnaces, stationary gas turbines, and other fixed pollution sources with low-concentration particulate matter (≤50 mg/m3). When the measurement result exceeds 50 mg/m3, it is expressed as ">50 mg/m3". When the sampling volume is 1 m3, the method's detection limit in this document is 0.2 mg/m3, and the measurement limit is 0.8 mg/m3. 2. Normative references The content of the following documents is an integral part of this document through normative references in the text. Among them, the referenced documents with a specified date apply only to the version corresponding to that date; for the referenced documents without a specified date, the latest version (including all amendment sheets) applies to this document. - GB/T 16157: Determination of Particulate Matter in Exhaust Gas from Fixed Pollution Sources and Sampling Methods for Gaseous Pollutants - HJ/T 48: Technical Specifications for Smoke Samplers - HJ/T 397: Technical Specifications for Fixed Source Waste Gas Monitoring - HJ 836: Determination of Low-Concentration Particulate Matter in Fixed Pollution Source Exhaust Gas—Weight Method
