锅炉大气污染物排放标准
锅炉大气污染物排放标准是国家对锅炉大气污染物排放的有关法律法规的要求。
它的作用是确保锅炉大气污染物排放不超过规定的标准，以保护环境和人们的健康。
锅炉大气污染物排放标准有不同的分类，其中最常见的是烟气排放标准和废气排放标准。
烟气排放标准指的是锅炉烟气中挥发性有机物（VOCs）、烟尘、氮氧化物（NOx）和二氧化硫（SO2）的排放标准。
废气排放标准指的是锅炉废气中颗粒物（PM10）、挥发性有机物（VOCs）、氮氧化物（NOx）和二氧化硫（SO2）的排放标准。
锅炉大气污染物排放标准的制定是为了防止空气污染，为此，国家将锅炉大气污染物排放标准分为严格标准、基本标准和特别标准三种。
严格标准要求排放量不超过国家规定的上限，基本标准要求排放量在一定的范围内，而特别标准则要求排放量不低于国家规定的下限。
此外，国家还将锅炉大气污染物排放标准分为日排放量和年排放量标准，日排放量标准要求每日排放量不超过国家规定的上限，而年排放量标准要求每年排放量不超过国家规定的上限。
通过制定锅炉大气污染物排放标准，可以有效防止空气污染，确保环境和人们的健康。
由于各家企业对锅炉大气污染物排放标准的执
行情况不一，因此，国家将对违反排放标准的企业进行惩罚，以确保大气污染物排放标准的有效执行。

其次，针对不同类型的锅炉，我国也制定了不同的大气污染物排放标准。
例如，对于燃煤锅炉和燃油锅炉，其排放标准和要求是不同的。
燃煤锅炉在燃烧过程中会产生大量的烟尘和二氧化硫，因此其排放标准相对更为严格。
而燃油锅炉则在燃烧过程中产生的污染物排放相对较少，其排放标准相对宽松一些。
此外，我国还对锅炉的运行和管理提出了一系列的要求，以保证锅炉在运行过
程中能够达到大气污染物排放标准。
例如，要求锅炉必须定期进行清洁和维护，以保证燃烧效率和排放性能。
同时，对于超标排放的锅炉，我国也对其进行了处罚和整改要求，以确保锅炉排放达标。
总的来说，锅炉大气污染物排放标准的制定和实施，对于保护环境、改善空气
质量起到了重要的作用。
通过严格的排放标准和管理要求，可以有效地减少大气污染物的排放，保护大气环境和人类健康。
希望在未来，我国能够继续加大对锅炉大气污染物排放的监管力度，推动工业生产向更加清洁、环保的方向发展。

Emission Standard of Air PollutantsFor Coal-burning Oil-burning Gas-fired Boiler锅炉大气污染物排放标准Issued on 12/03/1999 Implemented as of 03/01/2000 ⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯−PrefaceThis standard is developed for the purpose of implementing the Environmental Protection Law of the People’s Republic of China and the Air Pollution Prevention & Control Law of the PRC, controlling emission of pollutants from boilers and preventing and controlling air pollution.This standard is a revision of GB13271-91, Emission Standard of Air Pollutants for Coal-burning Oil-burning Gas-fired Boiler.The main amendment made in this standard includes: the applicable scope of the standard is further clarified, added with blackness of smoke dust and flue gas and maximum allowable emission concentration limit of sulfur dioxide for natural ventilation coal-burning boiler with a capacity<0.7MW (1t/h), and blackness of smoke dust and flue gas and maximum allowable emission concentration limit of sulfur dioxide and nitrogen oxide for oil-burning and gas-fired boiler.⎯ GB13271-91 will be avoided as of the day when this standard goes into effect;⎯ this standard is proposed by the Scientific & Technological Standard Department under the State Environmental Protection Bureau;⎯ this standard was initially issued in September 1983 and revised for the first time in May 1992; and⎯ State Environmental Protection Bureau is responsible for interpretation of this standard.State Environmental Protection StandardGWPB 3-1999Replacing GB 13271-91 Emission Standard of Air Pollutants for Coal-burning Oil-burning Gas-fired Boiler1 ScopeThis standard specifies by years such emission limits for boilers as the maximum allowable emission concentration of smoke dust, sulfur dioxide and nitrogen oxide and the blackness of smoke dust.This standard applies to management of air pollutant emission from coal-burning, oil-burning and gas-fired boilers with various capacities and for different purposes, except for the coal powder power generation boiler and any single unit of power generation boiler with an output greater than 45.5MW (65t/h), and to evaluation, design and completion acceptance of the environmental effect of the construction project and management of pollutant emission after completion of such project.For any boiler using begasse, saw dust, rice husk or bark as its fuel, the maximum allowable emission concentration of air pollutants for coal-burning boiler in this standard shall be referred to.2 Quoted standardsThe articles included in the following standards form the articles of this standard by being quoted in this standard.GB 3095-1996 Environmental Air Quality StandardGB 5468-91 Boiler Smoke Dust Test MethodGB/T 16157-1996 Method for Determination of Particles & Sampling of Gaseous Pollutants in Exhaust Gas from Stationary Pollutant Source3 Definition3.1 Standard statusThe status of boiler flue gas under the temperature of 273K and pressure of 101 325 Pa is called for short “standard status”. The emission concentrations specified in this standard mean the values for dry flue gas under the standard status.3.2 Initial emission concentration of smoke dustIt means the emission concentration of smoke dust at the flue gas outlet of the boiler or before the inlet of the purification unit.3.3 Emission concentration of smoke dustIt means the smoke dust emission concentration of boiler flue gas that has passed through the purification unit. For a boiler not installed with any purification unit, the initial emission concentration of smoke dust is just the emission concentration of boiler smoke dust.3.4 Natural ventilation boilerNatural ventilation is a ventilation method where the pressure difference caused by the difference between the internal and external temperatures of chimney is utilized to suck the air into the furnace for combustion and emit the combustion product into the air. A boiler using natural ventilation method instead of mechanical ventilation with FD and ID fans is called a natural ventilation boiler.3.5 Ash content of arrival referenceThe ash content determined using the coal in arrival state as the reference, which may also be ⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯called “ash content of application reference”, is represented with “Aar”. 3.6 Excess air coefficientThe ratio of actual air consumption during combustion of fuel to the theoretical air demand is represented with “D ”. 4 Technical specifications 4.1 Classification of applicable areasClass I, II and III areas mentioned in this standard mean the classified environmental air quality functional areas as defined in GB 3095-1996, Environmental Air Quality Standard . The “two control areas” mentioned in this standard means the range of acid rain control area and sulfur dioxide pollution control area as defined in the Response by the State Council to Questions Concerning Acid Rain Control Area & Sulfur Dioxide Pollution Control Area . 4.2 Division of timeThis standard divide the time into two periods according to the years when the boilers are completed and put into service, for which different air pollutant emission standards shall be observed.Period I: boilers completed and put into service before December 31, 2000; andPeriod II: boilers completed and put into service as of January 1, 2001 (including boilers approved for building but not completed or put into service and those completed and put into service but required to be expanded or reformed).4.3 The limit values of maximum allowable emission concentration of smoke dust and blackness of flue gas for boilers shall be as specified in Table 1 according to the time periods.
