GB/T 16157-1996 The determination of particulates and sampling methods of gaseous pollutants emitted from exhaust gas of stationary source (English Version)
1 Subject Content and Application Scope
1.1 This standard specifies the determination of particulates and sampling methods of gaseous pollutants emitted from exhaust gas of flue, chimney and exhaust funnel (hereinafter referred to as flue) and other stationary sources.
1.2 This standard is applicable to the determination of particulates and sampling of gaseous pollutants emitted from exhaust gas of boiler, industrial kiln, furnace and other stationary source.
2 Definitions
2.1 Particulates
Particulates refer to solid and liquid granular substance suspending in the emission gas generated by fuel and other substance during the process of burning, composition, decomposition as well as various materials in the mechanical processing.
2.2 Gaseous pollutants
Gaseous pollutants refer to various pollutants dispersed over the emission gas in gaseous state.
2.3 Dry exhaust gas at standard condition
Dry exhaust gas at standard condition refers to the moisture free exhaust gas when the temperature is 273 K and pressure is 101300 Pa.
3 Determination and Calculation Contents
3.1 Determination of exhaust parameters (temperature, pressure, moisture content and element).
3.2 Calculation of exhaust density and gas molecule.
3.3 Determination of exhaust flow rate and flow.
3.4 Determination of particulates in exhaust gas and calculation of emission concentration and emission rate.
3.5 Sampling of gaseous pollutants in exhaust gas and calculation of emission concentration and emission rate.
4 Basic Requirements of Sampling
4.1 Sampling condition
The sampling shall be carried out when the production equipments are at normal operation or at the specified operation condition according to the requirements of standards for the pollutants emission.
4.2 Sampling location and sampling point
4.2.1 Sampling location
4.2.1.1 Sampling location shall be prior selected at the vertical pipe section and turn aside flue elbow and cross-section position with rapid change. Sampling position shall be set no less than 6 times the diameter away from the downstream direction of the elbow, valve and reducer pipe and no less than 3 times the diameter away from the upstream direction of above parts. For rectangular flue, the equivalent diameter D = 2AB / (A + B), where A and B are side lengths.
4.2.1.2 For gaseous pollutants, the sampling location may not be restricted with above provisions due to the even mix, but it shall turn aside the vortex cavity. If simultaneously determinate the exhaust flow, the sampling location is selected according to 4.2.1.1.
4.2.1.3 Sampling location shall turn aside the locations that may danger the testing personnel.
