GB/T 34340-2017

This standard specifies technical requirements for evaluating the operational performance of coal-fired flue gas denitration installations, including assessment indicators, testing methods, and evaluation procedures. It is applied in the environmental management and compliance verification of coal-fired power plants and industrial boilers in China, ensuring that selective catalytic reduction (SCR) or selective non-catalytic reduction (SNCR) systems effectively reduce nitrogen oxide emissions. The standard is used by operators, regulators, and third-party testing agencies to benchmark denitration efficiency, energy consumption, and reagent usage during routine or periodic performance assessments.
