GB13223
Foreword
This standard is formulated in accordance with the provisions of Article 7 of the "Atmospheric Pollution Prevention and Control Law of the People's Republic of China". GB13223-91 "Air Pollutant Emission Standard for Coal-fired Power Plants" is a relatively new standard that was implemented on August 1, 1992. Therefore, this standard takes into account the connection with GB13223-91: the two periods 1 and I are divided into this standard The thermal power plants included in each are consistent with the "existing thermal power plants" and "newly expanded and improved thermal power plants" in GB13223-91, and the technical content is basically the same. The focus of the revision of this standard is to formulate emission standards for various types of air pollution in sub-periods. This standard is based on the characteristics of my country's atmospheric sulfur dioxide and acid rain pollution that are increasingly intensifying and thermal power plants are key industries that emit sulfur dioxide. This standard applies to new, Expansion or reconstruction of thermal power plants (divided into the second period by this standard) shall implement dual control of the total maximum emission of sulfur dioxide and the emission concentration of each smoke window. In other areas, the control of sulfur dioxide emissions of the whole plant shall be implemented. At the same time, the formulation of smoke and dust emission standards for thermal power plants during this period takes into account the promotion of the application of high-efficiency electrostatic precipitators with four electric fields. In addition, according to the fact that my country has begun to introduce low-nitrogen combustion technology for boilers in recent years, in order to promote the promotion and development of this technology and early control the emission of ammonia oxides in the thermal power industry, this standard stipulates the standard limit for the emission of nitrogen oxides for the first time. This standard will replace GB13223-91 "Air Pollutant Emission Standard for Coal-fired Power Plants" from the date of implementation. This standard is proposed by the Science and Technology Standards Department of the National Environmental Protection Administration. This standard is interpreted by the National Environmental Protection Administration. 1 Scope
National Standard of the People's Republic of China
Emission standard of air pollutants for thermal power plants
Emission standard of air pollutants for thermal power plantsGB13223—1996
Replaces GB13223--91
This standard stipulates the maximum allowable sulfur dioxide emissions, smoke emission concentration and smoke blackness of thermal power plants by year, and stipulates the maximum allowable emission concentrations of sulfur dioxide and nitrogen oxides from thermal power plants in period III. This standard applies to the emission management and construction of thermal power plant boilers with a single output of 65t/h or more, except for layer-fired furnaces and stoker furnaces, and pulverized coal power generation boilers with a single output of 65t/h or less. Project environmental impact assessment, design, completion acceptance and post-completion emission management. www.bzxz.net

The provisions contained in the following standards constitute provisions of this standard through reference in this standard. At the time of publication, the editions indicated were valid. All standards are subject to revision and parties using this standard should explore the possibility of using the latest version of the standard listed below. GB/T16157--1996 Determination of Particulate Matter and Sampling of Gaseous Pollutants in Exhaust from Stationary Pollution Sources 3 Definition
This standard adopts the following definitions:
Standard state
refers to the flue gas at a temperature of 273K, the state when the pressure is 101325Pa. The emission concentrations of all pollutants in this standard refer to the values ??in the dry flue gas standard state.
4 Technical content
4.1 Year division
This standard divides thermal power plants into the following three periods according to their age: 1 Period one - completed and put into operation before August 1, 1992 or initially New, expanded, or reconstructed thermal power plants whose designs have been reviewed and approved; period I—from August 1, 1992 to December 31, 1996, new, expanded, or reconstructed thermal power plants whose environmental impact reports have been reviewed and approved, including New, expanded, or reconstructed thermal power plants whose environmental impact report has been reviewed and approved before August 1, 1992, and whose preliminary design is pending review and approval);
Sub-period - Environmental impact report from January 1, 1997 New, expanded, or reconstructed thermal power plants awaiting review and approval. 4.2 Smoke and dust emission standards
4.2.1 The maximum allowable smoke and dust emission concentration from thermal power plant boilers is based on the solid slag discharge when the excess air coefficient α at the dust collector outlet is 1.7 (first and second periods) or 1.4 (sub-period) Depends on the basis of pulverized coal furnace. 4.2.2 The maximum allowable smoke emission concentration and smoke blackness from thermal power plant boilers in the first period shall be as specified in Table 1. National Environmental Protection Administration approved on 1996-03-07 and implemented on 1997-01-01
