译自英国Edie环境新闻网站2007/03/30报导 （原文网址http://www.edie.net/news/news_story.asp?id=12828） 更小更乾净的垃圾发电厂 比垃圾焚化炉更小更乾净的创新垃圾发电厂即将在英国问世。 这种发电厂利用新技术将不可回收的废弃物转化成乾净的发电 用合成气体（syn-gas）与高强度建筑材料，而电厂本身运作 所需能源也来自於产生的气体。 这种气体电浆（Gaspalsma）技术除了二氧化碳净排放量为零 （carbon neutral），其他污染排放也很低，电厂占地更只有 焚化炉的三分之一，跟焚化炉相比有许多优点。拥有该技术专 利的先进电浆电力（Advanced Plasma Power）公司总裁Andrew Hamilton表示：「我们的秘诀是把气化与电浆技术结合。这两 种现有技术结合的好处是能源需求大幅降低，整个过程的经济 效益也就因此完全不同。」 「中间会有一些二氧化碳排放，但因为有一半到三分之二的废 物是可生物分解的（自然分解过程原本就会产生二氧化碳）， 所以在发电过程中产生的二氧化碳是零。」二氧化碳排放量是 这个技术远胜过传统焚化炉的因素。 他还表示，这项技术已经顺利在测试厂中通过测试，现在准备 好要以更大规模组装。大小也是它赢过焚化炉的优点之一，更 是一大卖点：一个十五公尺高的发电厂只需要约一个焚化炉三 分之一的空间。 Andrew也提到：「因为所需建筑空间小，建筑高度跟烟囱高度 低，又非常乾净，所以非常适合都市环境使用。」 「但另一方面，因为它是模组化的，在一个幅员广阔的郡内设 置两三个点，跟集中到单一一个焚化炉相比，废物需要被运输 的距离减短很多。」 虽然目前鼓励减低包装、回收、再利用、垃圾减量的整体行动 可能会影响到这个公司的生意，Andrew并不认为垃圾发电厂会 面临无废物可烧的地步。 「我们的业务范围是那些无法消除、不能回收的东西，永远都 会有很多废物是需要被处理的。我们绝对支持回收与垃圾减量 ，但还是应该务实地考虑要怎麽对付其他垃圾。」 关於先进电浆电力的其他资讯可参考 www.advancedplasmapower.com. （该网站首页的简介（英文）附在本文最末） ---------------------------------------------- Waste-to-energy process promises smaller, cleaner plants (30 March 2007) Cutting edge waste-to-energy plants that are smaller and cleaner than incinerators could soon hit the UK market. The plants run a new process that transforms non-recyclable waste into a clean syn-gas, used to generate clean power and a high- strength building material, with the plant itself powered by the syn-gas it produces. Carbon-neutral and very low in emissions with plants around a third of the size of incinerators, the Gasplasma process can compete with incinerators on a number of counts, according to Andrew Hamilton, CEO of Advanced Plasma Power, the company that patented the process: "The trick here for us has been the combination of gasification and plasma. The benefit of combining these two existing technologies is that you substantially reduce the power requirements, and that transforms the economics of the process," he told edie. "You will get some CO2 coming out but a half to two-thirds of the waste is biodegradable so it's carbon neutral," he said, adding that the process beats incineration when it comes to the carbon balance. The process has passed tests in a pilot plant with flying colours and is now ready to be implemented on larger scale, he said. Numerous advantages over incinerators include size, a major selling point as the 15m-high plant takes up around a third of the space needed for an incinerator. "Because it's got a small building footprint with a low profile building and small stack, and it's very clean, it is very suitable for urban settings. "But equally, because it is modular, having two or three of these in a large spread-out county means the waste has to travel a lot less than if you have one incinerator in the middle of the county," he said. And while the company could feel threatened by increasing efforts to minimise packaging, recycle, re-use and cut out waste altogether, Andrew Hamilton does not see waste-to-energy plants ever running out of feedstock. "Our business is dealing with what can't be eliminated, what can't be recycled, there's always going to be a big volume of waste that has to be treated. Absolutely support recycling and waste minimisation but one has to be realistic about what to do with the rest of it." For more information on Advanced Plasma Power see www.advancedplasmapower.com. --- Advanced Plasma Power The Gasplasma Process is an Advanced Conversion Technology to convert a pre-treated waste feedstock into two recyclable products: a hydrogen rich synthetic or Syn gas and a vitrified material suitable for use as a replacement aggregate or building material. It is a two-stage gasification process; firstly gasifying the pre-treated waste feedstock in a fluid bed gasifier producing a syngas contaminated with tars and soot as well as solid chars and ash and secondly, using a plasma arc treatment to convert the residual soot tars and chars into further syngas which has consistent calorific values while simultaneously vitrifying the ash. It has been developed to: * maximise the generation of renewable energy * produce minimal waste residues and benign emissions * operate on a small footprint with minimal environmental impact. --
