The impact of nitrogen oxide emissions from chemical industrial furnaces on air pollution and other aspects cannot be ignored. This necessitates consideration of denitrification technology and equipment for chemical industrial furnaces. Due to its special nature, in accordance with GB 31570 "Emission Standard of Pollutants for Petroleum Refining Industry" and GB 31571 "Emission Standard of Pollutants for Petrochemical Industry" This document is compiled in accordance with the provisions of the "Standards". Chemical industrial furnace denitrification equipment

1 Scope

GB/T 47183-2026 is the Chinese national standard covering the deNOx plant on a chemical process furnace - the SCR or SNCR reactor, the reagent storage and injection, the catalyst layers and their management, and the ammonia slip that has to be kept down because it becomes a pollutant of its own. First edition, 19,000 words, and it belongs with the catalyst regeneration and analysis standards of this batch. It was issued on 27 February 2026 and has been in force since 1 September 2026, as a first edition. The document is under the responsibility of the China Petroleum and Chemical Industry Federation. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document specifies the classification and selection principles, performance requirements, low-NOx combustion denitrification equipment, and SNCR denitrification equipment for chemical industrial furnaces. Equipment, SCR denitrification equipment, manufacturing, and system acceptance and testing methods. This document applies to industrial furnaces used in chemical industrial production, such as heating furnaces, conversion furnaces, pyrolysis furnaces, gasification furnaces, incinerators, and calcining furnaces. Denitrification equipment (hereinafter referred to as "denitrification equipment"). Denitrification equipment for chemical industrial furnaces using coal as the heating method is specified in GB/T 21509. This document does not apply to denitrification equipment for chemical industrial furnaces such as incinerators and calciners located outside the plant boundary.
