Introduction

Scope of application and definition of the standard

This standard applies to the air and water pollutant emission permit management of industrial furnaces and kilns, and clarifies that industrial furnaces and kilns refer to thermal equipment such as smelting and roasting by using fuel combustion or electric energy conversion heat. According to the "List of Classification Management of Pollutant Emission Permits for Stationary Pollution Sources", pollutant emission units are divided into two categories: key management and simplified management.

Determination Method of Permitted Emission Limits

Emission outlet type	Calculation method	Applicable conditions
Main emission outlet	Benchmark exhaust volume method	When the benchmark exhaust volume is specified in the standard
	Performance value method	When there is no benchmark exhaust volume (refer to Table 6-7)
	Gas volume method	Biomass fuel or special operating conditions
Special time period	Actual emission conversion method	Heavy pollution weather response period

Feasible technical requirements for pollution prevention and control

Waste gas treatment technology

Smelting furnacePreferably adopts low-sulfur raw materials + bag dust removal + wet desulfurization combined technology; Heat treatment furnaceRecommends gas purification + electrostatic dust removal process.

Wastewater treatment case

A glass fiber enterprise uses the "neutralization + coagulation + reverse osmosis" process for desulfurization wastewater, and the fluoride removal rate reaches 92%.

Background of Standard Implementation

In order to implement the "Air Pollution Prevention and Control Law" and other laws and regulations, and respond to the requirements of the "Integrated Control Plan for Air Pollution from Industrial Furnaces" (Environmental Atmosphere [2019] No. 56), special emission permit technical specifications for industrial furnaces are formulated for the first time to strengthen the coordinated control of multiple pollutants such as particulate matter, sulfur dioxide, and nitrogen oxides.

Implementation Suggestions

Key management units should record operating parameters such as filter material replacement and desulfurization agent addition on a monthly basis
Emission outlets installed with CEMS need to conduct data verification every day
Manual monitoring should be carried out every quarter for unorganized emission points
Establish a complete environmental management ledger (keep for ≥3 years)
