Opening New Fuels for UK Generation

该项目旨在调查英国未来在燃烧系统中使用废物的潜力，以及此类废物的燃烧可能如何影响发电站应对电力需求变化的能力。目的不是看当今的电力系统和废物焚烧管理系统，而是考虑如何设计一个合理的系统，以利用所有潜在的燃料流(并考虑到不同的废物将含有不同水平的微量元素，其中一些元素可能相当轻微)。重要的一点是，目前许多废物都是被填埋的-这意味着废物的能量含量都会损失，大量材料最终进入堆填区。在这里，我们将进行实验，观察不同类型的“废物”材料(例如，拆卸现场的木材)在燃烧和混烧(与煤)过程中的微量元素排放，以及对产生的灰烬进行分析。然后，结果将被用来生成发电厂燃烧废物的模型，并用来确定，对于所检查的废物，最合理的废物利用是在专用设施中燃烧还是混烧。显然，我们目前将审查的一些废物属于废物焚烧指令的范围(尽管所有废物都将是非卤化的)。我们将检查这是否在科学上是有效的。

This project seeks to investigate the potential for using waste materials within combustion systems within the UK in the future, and how the combustion of such wastes might affect the ability of a power station to respond to changes in electricity demand. The purpose is not to look at today's electricity system and systems of governance with respect to combustion of wastes, but to consider how a rational system would be designed that utilised all potential fuel streams (and takes into account that different wastes will contain different levels of trace elements, some of which may be quite minor). An important point is that many wastes are currently landfilled - meaning that both the energy content of the waste is lost and a bulky material ends up in landfill.Here, we will conduct experiments looking at emissions of trace elements during combustion and co-firing (with coal) of different types of "waste" materials (for example, wood from demolition sites), together with analysis of ashes produced. The results will then be used to generate models of power plants burning wastes, and used to determine whether, for the wastes examined, the most rational use of the waste is combustion in dedicated facilities or co-combustion. It is clear that some of the wastes we will examine currently fall within the remit of the waste incineration directive (though all will be non-halogenated). We will examine whether this is scientifically valid.
