GB 28663-2012Emission standard of air pollutants for ironmaking industry (English PDF)

Foreword

In order to implement the laws and regulations of "Environmental Protection Law of the

People's Republic of China", "Air Pollution Prevention Law of the People's Republic of

China", "State Council on Scientific Development and Strengthening Environmental

Protection" etc. and "State Council on Preparation of Main Functional Area Planning",

protect the environment, prevent pollution and promote the progress of ironmaking

industry's production processes and pollution control technologies, this Standard is

formulated.

This Standard specifies the emission limits, monitoring and control requirements of air

pollutant concentration for ironmaking manufacturing enterprises. In order to promote

the coordinated development of regional economy and the environment, promote the

adjustment of economic structure and the transformation of economic growth mode,

and guide the development of production processes and pollution control technologies

of ironmaking industry, this Standard specifies the special emission limits of air

pollutants.

The pollutant emission concentration in this Standard is mass concentration.

The relevant national pollutant emission standards are applicable to water pollutants,

odor pollutants and environmental noise emitted by ironmaking manufacturing

enterprises; the national solid waste pollution control standards are applicable to the

identification, treatment and disposal of discharged solid wastes.

This Standard is released for the first time.

From the date of implementation of this Standard, the emission control of air pollutants

of ironmaking manufacturing enterprises shall be executed in accordance with the

specifications of this Standard; the relevant specifications in "Standard of smoke and

dust emission for industrial kiln and furnace" (GB 9078-1996) and "Standard of smoke

and dust emission for industrial kiln and furnace" (GB 16297-1996) are not executed

anymore.

For those pollutants that are not specified in this Standard, the local provincial

governments can establish local pollutant emission standards; for those pollutants that

have been specified in this Standard, it can establish local pollutant emission standards

that are more strict than this Standard.

This Standard was formulated by the Technology Standard Office of the Ministry of

Environmental Protection Science.

Emission standard of air pollutants for ironmaking industry

1 Scope

This Standard specifies the emission limits, monitoring and control requirements of air

pollutants for ironmaking manufacturing enterprises or production facilities, and the

implementation and supervision of the standard and other relevant specifications.

This Standard applies to the air pollutant emission management of existing ironmaking

manufacturing enterprises or production facilities, and the environmental impact

assessment, environmental protection facility design, environmental protection

acceptance after completion and air pollutant emission management after launching

into production of ironmaking industry's construction projects.

This Standard applies to the pollutant emission behavior permitted by law; the site

selection of newly established pollution sources and the management of existing

pollution sources within the special protection area shall be in accordance with the

relevant specifications of laws, regulations and rules such as "Air Pollution Prevention

Law of the People's Republic of China", "Water Pollution Prevention Law of the

People's Republic of China", "Marine Environmental Protection Law of the People's

Republic of China", "Solid Waste Pollution Prevention Law of the People's Republic of

China" and "Environmental Impact Assessment Law of the People's Republic of China".

3 Terms and definitions

The following terms and definitions apply to this Standard.

3.1

Blast furnace ironmaking

The production process of using blast furnace to smelt pig iron. Blast furnace is the

main part of the production process; the iron ores, fuels and fluxes that are loaded from

the upper part move downward; air fuels are blew into the lower part to burn; a large

amount of high-temperature reducing gas is generated and moved upward; after a

series of physical-chemical processes such as heating, reduction, melting, slagging,

carburizing and desulfurization, the furnace charge turns into liquid slag and pig iron.

3.2

Existing facility

Before the implementation of this Standard, the ironmaking manufacturing enterprises

or production facilities that have been built and launched into production or the

environmental impact assessment documents have been approved.

3.3

New facility

The new, rebuilt and expanded ironmaking industry production facility's construction

projects of which the environmental impact assessment documents have been

approved, from the date of implementation of this Standard.

3.4

Standard condition

The condition when the temperature is 273.15K and the pressure is 101325Pa. The

air pollutant emission concentration specified in this Standard is on the basis of dry

gases under standard conditions.

3.5

Blast furnace cast house

The place where blast furnace casts iron, including tap hole, main tap drain, sand hole,

iron runner, residue runner, tank level, swinging spout and other...
