燃煤热风炉改造生物质热风炉环境与经济效益并存

2018-05-31 21:38:43 常州亿创钣金加工厂 阅读

受我国能源分布影响,大部分工业热风炉均是燃煤热风炉,燃煤过程中产生的SO2、NOx等污染物,对大气环境造成较大的污染,为改善空气质量,许多城市已逐步对中小型燃煤热风炉进行淘汰或改造。生物质热风炉是根据生物质燃料的燃烧特性研发的,具有清洁环保、节能高效的优势,生物质成型燃料经过粉碎、压缩而成,密度高、水分含量大,若现运行中的燃煤热风炉不加以改造而直接使用生物质成型燃料,热风炉容易出现出力小、容易冒黑烟等现象。

Influenced by the energy distribution in China, most of the industrial hot blast furnaces are all coal fired hot air furnaces. The pollutants such as SO2 and NOx produced in the process of coal combustion have caused great pollution to the atmosphere. In order to improve the air quality, many cities have phased out or modified the small and medium coal-fired hot blast furnaces.Biomass hot blast furnace is developed on the basis of the combustion characteristics of biomass fuel. It has the advantages of clean environmental protection, energy saving and high efficiency. The biomass briquette fuel has been crushed and compressed, with high density and high moisture content. If the coal-fired hot air stove is not reformed in the current operation, it is easy to use biomass briquette fuel and the hot blast furnace is easy. The emergence of small power, easy to smoke black smoke and other phenomena.

   将燃煤热风炉改造成成型生物质热风炉,一方面能有效降低SO2、NOx的排放量,另一方面可避免改用燃油(气)热风炉带来的经济负担,还对促进可再生能源的发展、实现农业和林业有机废弃物的综合利用、优化能源结构具有重要作用。

The transformation of a coal-fired hot blast stove into a biomass hot blast stove can effectively reduce the emission of SO2 and NOx, on the other hand, avoid the economic burden of using the fuel (gas) hot blast stove. It also plays an important role in promoting the development of renewable energy, the realization of the comprehensive utilization of organic wastes in agriculture and forestry and the optimization of energy structure. Use.

   但由于我国生物质成型燃料产业正处在发展初期,市场尚未成熟,质量、价格相差较人,供求不稳定,行业标准还不健全,需要国家有关部门制定相应的配套政策扶持和推动产业发展。

   将燃煤热风炉改造为成型生物质热风炉在经济和技术上均可行:可有效降低SO2的排放,烟气经除尘可达到国家排放标准,具有明显的环境效益;可促进可再生能源的发展,实现农业和林业有机废弃物的综合利用,具有一定的社会和经济效益。

However, because of our country's biomass fuel industry is in the early stage of development, the market is not mature, the quality and price are different, the supply and demand are not stable, the industry standard is not sound, and the relevant government departments should formulate corresponding policies to support and promote the industrial development.

It is feasible both economically and technically to transform a coal-fired hot blast stove into a biomass hot blast stove, which can effectively reduce the emission of SO2. The flue gas can reach the national emission standard and has obvious environmental benefits. It can promote the development of renewable energy and realize the comprehensive utilization of organic waste materials of Agriculture and forestry, and has a certain society. And economic benefits.
