GB 13223-2011Emission standard of air pollutants for thermal power plants (English PDF)

Foreword

In order to carry out "the Protection Act of the People's Republic of china",

"Atmospheric Pollution Prevention Act of the People's Republic of China", and "The

state council on implementing the scientific concept of development - to strengthen

environmental protection decision" and other laws and regulations; improve the

quality of environment; prevent and cure the pollution of the air pollutants from thermal

power plants; promote technical progress and sustainable development of thermal

power industry, this Standard is formulated for above purposes.

This Standard defines the requirements of concentration limits, supervision and

monitor to the emission of air pollutants of thermal power plants.

This Standard's concentrations of pollutants emission are qualitative concentrations.

This Standard was initially published in 1991, first-time revised in 1996 and

second-time revised in 2003.

The main contents of this revision are as followed.

—ADJUST the concentration limits of the air pollutants' emission;

—DEFINE the time limits for current thermal power boilers to reach stricter level

of concentration limits of emission;

—CANCEL the provision about maximum allowable emission rate of sulfur

dioxide for entire plant;

—ADD concentration limits of emission of gas boilers' air pollutants;

—ADD specific emission limits of air pollutants.

Water pollutants, odor pollutants and environmental noise discharged by thermal

power plants are subject to the national emission standard of pollutants. The

identification, treatment and disposition of producing solid waste are subject to the

national standard of controlling solid waste pollution.

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

for thermal power plants must be enforced according to provisions of this Standard.

And the relavant provisions of national emission standard "Emission standard of air

pollutants for thermal power plants" (GB13223—2003) are no longer required.

For those items of air pollutants not yet specified in this Standard, the local provincial

government can formulate emission standard of local pollutants; to those items of air

pollutants which have been specified in this Standard, the local provincial government

level can formulate stricter emission standard of local pollutants.

This Standard was organized and initiated by the Ministry of Environmental Protection

Science and Technology Standards Division.

This Standard was drafted by organizations. Chinese Research Academy of

Environmental Sciences, and State Power Environmental Protection Research

Institute.

This Standard was approved by the Ministry of Environmental Protection on July 18,

2011.

This Standard shall be implemented from January 1, 2012.

This Standard shall be explained by the Ministry of Environmental Protection.

Emission standard of air pollutants for thermal power plants

1 Scope

This Standard defines the requirement of concentration limits, supervision and

monitor to the emission of air pollutants for thermal power plants; and related

provisions of implementation and supervision of standard.

This Standard applies to air pollutants emission management for current thermal

power plants and for the plant project's environmental influential assessment,

environmental engineering, acceptance of environmental protection and after

go-into-production.

This Standard applies to the coal-fired power boilers of which output of single-unit is

more than 65 t/h, except stoker furnace and layer burner; various coal-powder power

boilers with different capacities; oil-fired and gas-fired power boilers of which output of

single-unit is more than 65t/h; and various gas turbine power plants with different

capacities. For those boilers using fuel of gangue, biomass, oil shale, petroleum coke

etc. and of which output of single-unit is more than 65 t/h, the requirement of

circulating fluidized bed-boilers' pollutants emission control in this Standard shall be

referred for implementation. Gas turbines of integrated gasification combined cycle

(IGCC) carry out gas turbine's emission limits of burning gas in this Standard.

This Standard is not applicable to the thermal power plants fired with domestic wastes

and hazardous wastes.

This Standard applies to lawful behavior of pollutants emission. For new location

set-up for pollution source and the management of current pollution source within

special protected, they shall be carried out according to "The Law of the People's

Republic of China on the Prevention and Control of Atmospheric Pollution", " The Law

of the People's Republic of China on the Prevention and Control of Water Pollution",

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

of the People's Republic of China on the Prevention and Control of Environmental

Pollution by Solid Wastes", "The Law of the People's Republic of China on Evaluation

of Environmental Effects" and other laws and regulations.

3 Terms and Definitions

The following terms and definitions apply to this Standard.

3.1

Thermal power plant

Power plant of burning solid, liquid or gaseous fuel

3.2

Standard condition

The condition of gas, at temperature of 273K and at pressure of 101 325 Pa, is called

"standard condition" for short. The specified concentration of air pollutants in this

Standard refers to the value of dry gas, under this Standard Condition.

3.3

Oxygen content

When burning the fuel, the extra free oxygen containing in the gas is generally

expressed by dry-volume-percentage.

3.6

Arch fired furnace

The burning space of W-shape flame that is formed when the burner is placed on

furnace vault of front-or-back walls; fuel and air are jetted downward; after rotating

180 degrees, combustion products are discharged upward from the middle of

front-and-back vault.

3.7

Key region

According to the requirements of environmental protection, it refers to the regions

where have high density of land development; have weakness of environmental

carrying capacity; or have little atmospheric environmental capacity, fragile ecological

environment; and are easy to occur serious air pollution; so that controlling emission

of air pollutants is strictly required.
