ASTM D6522 Standard Test Method for Determination of Nitrogen Oxides, Carbon Monoxide, and Oxygen Concentrations in Emissions from Natural Gas-Fired Reciprocating Engines, Combustion Turbines, Boilers, and Process Heaters Using Portable Analyzers
ASTM D6522用便携式分析仪测定燃天然气的往复式发动机,燃气轮机,燃烧炉和工艺加热器排放的氧化氮,一氧化碳和氧浓度的标准试验方法
The results of this test method may be used to determine nitrogen oxides and carbon monoxide emissions from natural gas combustion.
This test method may also be used to monitor emissions to optimize process operation for nitrogen oxides and carbon monoxide control.
1. Scope
1.1 This test method covers the determination of nitrogen oxides (NO and NO2), carbon monoxide (CO), and oxygen (O2) concentrations in controlled and uncontrolled emissions from natural gas-fired reciprocating engines, combustion turbines, boilers, and process heaters. Due to the inherent cross sensitivities of the electrochemical cells, this test method should not be applied to other pollutants or emission sources without a complete investigation of possible analytical interferences and a comparative evaluation with EPA test methods.
1.1.1 The procedures and specifications of this method were developed during laboratory and field tests funded by the Gas Research Institute (GRI). Comparative emission tests were conducted only on natural gas-fired combustion sources.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
