木质颗粒与碳化颗粒:哪个更环保?

发布日期:2016-5-17 13:34:52  浏览量:

木质颗粒被广泛认为是时下最环保的燃料之一。这意味着其可以减少能源生产行业的温室气体排放量。更重要的是,从完全可再生途径获取的木材废物能使百万吨生物质得以留存。

Wood pellets are widely recognized as one of the most eco-friendly types of fuel nowadays. It means that their quality could reduce the greenhouse gas emissions of the energy production industry. What is more, getting wood residues from completely renewable sources leads to the preservation of millions tons of biomass.


然而,碳化颗粒被认为是燃料市场的一个新的未来。因此,碳化生物质是相对统一的产品,可以在发电厂进行焚烧,运作很像煤。这也有助于降低温室气体排放和空气污染。

However, torrefied wood pellets are considered as a new future of the fuel market. Thus, torrefied biomass is a relatively consistent and uniform product that could be burned at power plants, functioning much like coal. Herewith, it also helps to lower greenhouse gas emissions and much lower air pollution. 


木质颗粒的不足

Wood Pellet disadvantages

然而,木质颗粒也有一些不足。在购买和安装锅炉中花费的初始成本。更重要的是,需要花时间在定期清理锅炉和清空灰箱上。木质生物质比其他类型的燃料体积大得多,所以需要大量的空间(料斗或木材商店)来存储木质颗粒。

However, there are some disadvantages of wood pellets. Thus, the initial costs should be spent on buying and installing the boiler. What is more, it is needed to be spent some time on cleaning boilers and empting ash bins on regular basis. Wood biomass is much bulkier than other types of fuel, so it is needed a lot of space (hopper or wood store) to store wood pellets dry.

而最重要的,如果你想真正环保,你应该了解你所在地区木质颗粒可用性,在运输过程中随着颗粒运输距离越大,排放的碳越多。

And the most important, if you want to be really eco-friendly, you should check out availability of wood pellet in your region, as the further pellets are transported the greater amount of carbon is released while transporting.


碳化木质颗粒的优势

Advantages of torrefied wood pellets

碳化木质颗粒被广泛用于发电厂,由于其运作很像煤炭,能量密度很高。应当注意的是,工业木质颗粒比碳化木质颗粒燃烧效率低。碳化木质颗粒可以保留90%原始生物质能。这样一来,使用碳化颗粒的话,燃煤电厂可以接近最大容量运作。

Torrefied wood pellets are widely used by power plants due to its functioning much like coal and high level of energy density.It should be noted that industrial wood pellets are burned less efficiently than torrefied wood pellets. Thus, torrefied wood pellets could retain up to 90% of the original biomass energy. As a result, coal plants on torrefied wood granules could operate at closer to their maximum capacity.

 

与普通木质颗粒比较,更高一级的体积和能量密度使碳化木质颗粒运输更经济。此外,碳化生物质的疏水能力使其不太可能分解,使颗粒更容易存储。

A higher level of bulk and energy density allows pelletized torrefied wood be much more economical to ship and transport in comparison with regular wood pellets. In addition, the hydrophobic ability of torrefied biomass makes it less likely to degrade than regular wood granules, making pellets easier to store.

 

碳化生物质的热值比木质颗粒热值的水平高出1.5倍。碳化木质颗粒的水分含量为1%左右,而木质颗粒的水分含量可以达到10%左右。因此,碳化木质颗粒可以减少化石燃料的使用,并使燃煤发电厂降低温室气体排放,改善空气质量。

The caloric value of torrefied biomass is 1.5 times higher than the level of caloric value of wood pellets. The moisture content of the torrefied wood pellets is around 1%, while the moisture content of wood pellets could reach 10 and more percent. So, torrefied wood pellets reduce the use of fossil fuel and allow coal power plants to lower GHG emissions, improving air quality.


碳化木质颗粒:缺点

Torrefied wood pellets: drawbacks

乌克兰生物燃料门户pellets.wood.com的分析师介绍了一些碳化生物质的缺点。首先,与普通的木质颗粒相比,碳化木质颗粒更难得到,因为碳化木质颗粒行业尚未被广泛开发。其他缺点是与碳化颗粒制作过程联系相关。因此,二氧化碳的排放量与过程中的温度和时间相关。每种类型的木材有其理想的燃烧温度,在较高或较低的温度下燃烧木材可能会增加排放,使能量产率降低。碳化过程有很多不确定性因素。

The analysts of Ukrainian Biofuel Portal pellets.wood.com described some disadvantages of the torrefied biomass. For the first, torrefied wood pellets are more difficult to find in comparison with regular wood pellets, as torrefied wood pellet industry has not been so widely developed yet. Other drawbacks are linked with the process of making torrefied pellets. Thus, CO2 emissions are connected with temperature and time the process takes. Each type of wood has its ideal burning temperature and burning wood at a higher or lower temperature could increase emissions and make a lower energy yield. And still, so many uncertainties about the torrefaction are needed to be explained.


总结

综上所述,木质颗粒和碳化木质颗粒都可以用于供热和发电。木质颗粒以及碳化木质颗粒是碳中性的,被公认为能够改善空气质量,减少温室气体排放的可再生燃料。但哪个是更环保的燃料?

So, according to the above information, both wood pellets and torrefied wood pellets are used for heating and generating electricity. Wood pellets as well as torrefied wood pellets are carbon neutral and recognized as a renewable fuel that improves air quality, reducing greenhouse gas emissions. But which one is a greener type of fuel?


据我们所知,碳化木质颗粒比普通木质颗粒热量更高。它的防水性能,使其比木质颗粒燃料更易于储存。碳化生物质可与煤共烧,使燃煤电厂符合可再生能源标准。同时,具有较高的能量含量意味着需要更少的颗粒的出货量,能够减少运送颗粒燃料给客户时的二氧化碳的排放量。碳化生物质最大的好处是,它可以碳化林业副产品和家具厂锯木。否则,他们进入垃圾填埋场,释放甲烷,比排放二氧化碳对环境的负面影响更大。

As far as we now, torrefied wood pellets have a much higher heat content than regular wood pellets. Its water-repellent property has a great positive influence on moisture problems that appears while storing fuel in comparison with wood pellets. Torrefied biomass could be co-fired along with coal, allowing coal-fired power plants comply with renewable energy standards. To have a higher energy content means that it will be needed less pellet shipments, what much reduces CO2 emissions while transporting pellet fuel to customers. And the most important benefit of the torrefied biomass is that it could be used industrial bi-product from forestry sawmills or furniture manufacturers for torrefaction. Otherwise, they go into landfill and release methane, which has much higher negative environmental impact than CO2 emissions.
