A More Efficient Incinerator for Hazardous Waste

危险废物焚化炉的许可程序通常 要求进行一次燃烧试验，试验表明焚化炉 实现至少99.99%的主要危险物质销毁 件. 危险废物焚烧炉的设计目的是 实现这一目标，具有相当大的安全裕度。 然而，不幸的是，他们有时无法实现 材料的破坏程度，特别是 当危险物质以低初始浓度存在时， 浓度的 提出了理论论据，表明 传统的焚化测试 谬误，可以高估的程度，一个危险的 材料将被销毁。 这些论点得到以下方面的支持： 计算机建模并由实验室直接确认 测量. 一种提高焚烧炉效率的新方法， 提出了 计算机模拟表明，该方法可以 高效率和实验与一些困难， 焚烧，危险化学品表明， 可以实现1,000或更高的焚烧炉效率。 这项技术的商业化将使焚化炉 销毁有毒有机物质，减少排放 这些物质进入大气层。 虽然这是至关重要的 用于销毁二恶英，多氯联苯， 神经毒气和其他剧毒物质， 这种改善被认为是适度的，该计划是 预计具有广泛的适用性。

Permitting procedures for hazardous waste incinerators usually require a test burn in which the incinerator is shown to achieve at least 99.99% destruction of the principal hazardous components. Hazardous waste incinerators are designed to achieve this goal with a substantial safety margin. Unfortunately, however, they sometimes fail to achieve the required degree of destruction of the material, especially when the hazardous materials are present in low initial concentrations. Theoretical arguments are advanced which show that the conventional tests of incinerability involve a fallacy and can overestimate the extent to which a hazardous material will be destroyed. These arguments are supported by computer modeling and directly confirmed by laboratory measurements. A novel method for improving incinerator effectiveness is proposed. Computer modeling shows that this method can be highly effective and experiments with a number of difficult to incinerate, hazardous chemicals show that improvements in incinerator effectiveness of 1,000 or more can be achieved. Commercialization of this technology would allow incinerators to destroy toxic organic materials with reduced emissions of those materials to the atmosphere. While this is of critical importance to incinerators used to destroy dioxins, PCBs, nerve gases, and other extremely toxic materials, the costs of this improvement are thought to be modest, and the scheme is expected to have broad applicability.
