摘要:As the situation of air pollutants control is more severe and the policy of energy-saving and emission reduction related industries become stricter at current time, it’s urgent to carry out operation performance assessment work for flue gas desulfurization denitrification and dedusting equipment. This article analyses the current operation situation of the equipment of air pollutants emission and control in thermal power and steel industries in China, which shows the necessity and the urgency of a series of national technical specifications of operation performance assessment for flue gas desulfurization denitrification and dedusting equipment in key industries. Furthermore, the paper highlights the building of operation performance evaluation indicators system for coal-fired flue gas desulfurization denitrification equipment and dust collector for sintering flue gas from iron and steel industries, and the qualitative assessment requirements and the quantitative evaluation indicators, which could promote the construction of operation effectiveness assessment mechanism for air pollutants control equipment of key industries in China and accelerate the reliability and the effectiveness of the equipment operating in China by standardization.
