热风炉厂家为你讲解一些生物质热风炉有哪些排放标准?首先生物质热风炉主要是以废旧的麦秸秆等为主,在燃烧后会再次出现排放,本身作为新的环保设备,不能产生再次污染,根据环保部《关于生物质成型燃料有关问题的复函》,燃气热风炉对生物质成型燃料在燃烧过程中的大气污染排放提出了严格的标准:“应以燃气的排放标准来要求”生物质成型燃料,尽可能减少大气污染。

What are the emission standards of some biomass hot air furnaces for you? Firstly, biomass hot blast stove is mainly waste wheat straw, which will emit emissions again after combustion. As a new environmental protection equipment, it can not produce re-pollution. According to the Ministry of Environmental Protection's Reply to the Questions Concerning Biomass Briquette Fuel, gas hot blast stove has great influence on biomass briquette fuel during combustion process. Strict standards for air pollution emission are put forward: "Gas emission standards should be used to require" biomass briquette fuel to reduce air pollution as much as possible. 1、气体排放标准

1. Gas emission standards

据专家分析,生物质燃料热风炉燃烧后可实现CO2零排放,NOx微量排放,SO2排放量小于33.6mg/m3,烟尘排放量低于46mg/m3,相比燃煤、燃油热风炉来讲,其污染指数已经很低。根据国家对于大气污染物排放控制指标显示,热风炉排放标准为:SO2≤100mg/m3、燃气热风炉烟尘≤100mg/m3,因此生物质热风炉排放标准符合控制指标,并且排放浓度远远低于国家标准。

According to expert analysis, the biomass fuel hot blast stove can achieve zero CO2 emission, micro-emission of NOx, SO2 emission less than 33.6 mg/m3, and smoke emission less than 46 mg/m3. Compared with coal-fired and oil-fired hot blast stoves, its pollution index is very low. According to the national emission control index of air pollutants, the emission standard of hot-blast stove is SO2 < 100mg/m3, and the smoke and dust of gas hot-blast stove < 100mg/m3. Therefore, the emission standard of biomass hot-blast stove meets the control index, and the emission concentration is far below the national standard.

2、固体排放

2. Solid emissions

生物质热风炉除了排放气体以外,还有固体的排出,其固体主要成分是燃烧后的灰分。燃料包含70%左右的纤维含量,含硫量不到碳含量的1/10,硫硫和氯含量均小于0.07%,氮含量小于0.5%,因此固体灰分的含量也比较低,符合国家排放标准。

In addition to discharging gases, the biomass hot blast stove also discharges solids, the main component of which is ash after combustion. Fuel contains about 70% fiber content, less than 1/10 of carbon content, sulfur and chlorine content are less than 0.07%, nitrogen content is less than 0.5%, so the solid ash content is relatively low, which meets the national emission standards.

3、单台出力65t/h以上采用甘蔗渣、锯末、树皮等生物质燃料的发电热风炉,燃气热风炉参照《火电厂大气污染物排放标准》(GB13223-2003)规定的资源综合利用火力发电热风炉的污染物控制要求执行。

3. A single power generation hot-blast stove with over 65 t/h output using biomass fuels such as bagasse, sawdust and bark, and a gas-fired hot-blast stove shall be implemented in accordance with the requirements for pollutant control of the thermal power generation hot-blast stove for comprehensive utilization of resources stipulated in the Emission Standard of Atmospheric Pollutants for Thermal Power Plants (GB13223-2003).

4、单台出力65t/h及以下采用甘蔗渣、锯末、树皮等生物质燃料的发电热风炉,参照《热风炉大气污染物排放标准》(GB13271-2001)中燃煤热风炉大气污染物最高允许排放浓度执行。

4. The maximum allowable emission concentration of air pollutants from a coal-fired hot-blast stove with a single output of 65 t/h or less, which uses biomass fuels such as bagasse, sawdust and bark, is executed in accordance with the "Standard for Discharge of Air Pollutants from Hot-blast Stove" (GB13271-2001).

5、有地方排放标准且严于国家标准的,执行地方排放标准。

5, local emission standards should be implemented if there are local emission standards and are strictly national standards.

6、引进国外燃烧设备的项目,在满足我国排放标准前提下,燃气热风炉其污染物排放限值应达到引进设备配套污染控制设施的设计运行值要求。

6. On the premise of meeting the emission standards of our country, the emission limits of pollutants from gas-fired hot-blast stoves should meet the design and operation requirements of pollution control facilities for imported equipment.
