Opening New Fuels for UK Generation

该项目旨在研究英国未来在燃烧系统中使用废物材料的潜力，以及这些废物的燃烧如何影响发电站应对电力需求变化的能力。其目的并不是审视当今的电力系统和废物燃烧治理系统，而是考虑如何设计一个合理的系统，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，其中一些可能很小）。重要的一点是，目前许多废物都被填埋，这意味着废物中的能量损失，体积庞大的材料最终被填埋。在这里，我们将进行实验，研究不同类型的“废物”材料（例如，拆除现场的木材）在燃烧和共烧（与煤）过程中的微量元素排放，并分析产生的灰烬。然后，将利用这些结果生成发电厂焚烧废物的模型，并利用这些结果确定对所审查的废物而言，最合理的废物利用方式是在专门设施中焚烧还是混合焚烧。很明显，我们将研究的一些废物目前属于废物焚烧指令的范围（尽管所有废物都是非卤化的）。我们将研究这是否科学有效。

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.
