Publishdate：2019-04-15 Views：45
Recently, Henan Province issued the "2019 Special Plan for Industrial Furnace and Kiln Governance in Henan Province". The plan has made specific regulations on the emission concentrations of particulate matter, sulfur dioxide, and nitrogen oxides in flue gas from eight major industries, including non-ferrous metals (including zinc oxide), glass products (glass fiber), refractory materials, ferroalloys, ceramics, brick kilns, corundum, and lime. At the same time, it requires that all ammonia denitrification and ammonia desulfurization processes have ammonia escape levels less than mg/Nm3.
In order to implement the Notice of the People's Government of Henan Province on Issuing the Three Year Action Plan for Pollution Prevention and Control in Henan Province (2018-2020) (Yuzheng [2018] No. 30) and the Notice of the Henan Province Pollution Prevention and Control Leading Group Office on Issuing the Implementation Plan for the 2019 Air Pollution Prevention and Control Campaign in Henan Province (Yuhuan Campaign Office [2019] No. 25), we will deepen the special management of industrial furnaces and kilns, and continuously improve the environmental air quality throughout the province, Fully complete the standard emission control of industrial furnaces and kilns in our province, and formulate this plan based on the actual situation in our province.
