Gaseous renewable bioenergy sources, in the form of biogas and bio-syngas from biomass gasification, are facing a major issue in their utilisation because of the variable fuel properties and accordingly variable combustion performance. The vast change in CH4 concentration of biogas leads to strong fuel variability effects. For the cleaner bio-syngas, which is the gasification product of biomass, the issue of fuel variability is equally important. With variable fuel mixtures, there are concerns over the combustion efficiency/stability as well as the pollutant emissions. To deal with this challenge, a good understanding of the underlying physical and chemical processes of the combustion of biogas and bio-syngas is required. Based on fundamental research, this project is intended to obtain a thorough understanding on the important issue of fuel variability through integrated modelling and experimentation studies. The research has academic, environmental, social, as well as potential economic impacts.This joint project between the Universities of Lancaster and Sheffield aims to develop realistic and predictive physicochemical models for biogas and bio-syngas combustion and mappings between the combustion and emission characteristics and the fuel compositions for clean energy utilisation from renewable gaseous fuels. Based on rigorous modelling and experimentation, the project will deliver a thorough understanding of the utilisation of biogas and bio-syngas, highlighting the effects of variable composition. The project is intended to provide a better understanding of the complex physicochemical processes of bioenergy utilisation, which can advance bioenergy technology towards deployment.The project is composed of four inter-connected work packages: (1) WP1: development of chemical kinetic mechanisms, where a range of kinetic mechanisms for biogas and bio-syngas combustion will be developed and optimised; (2) WP2: large-eddy simulation of biogas and bio-syngas combustion, where parametric studies of fuel variability effects will be performed using advanced turbulent combustion models; (3) WP3: experimentation of biogas and bio-syngas combustion, where advanced combustion diagnostics will be systematically carried out; and (4) WP4: validation, integration and optimisation, where guidelines on the utilisation of biogas and bio-syngas with different compositions will be drawn.

以生物质气化产生的沼气和生物合成气为代表的气态可再生生物能源，由于燃料性质的变化以及相应的燃烧性能的变化，在其利用方面面临着重大问题。沼气中甲烷浓度的巨大变化导致了强烈的燃料变异性效应。对于生物质的气化产物--更清洁的生物合成气，燃料的可变性问题同样重要。对于不同的燃料混合物，人们对燃烧效率/稳定性以及污染物排放感到担忧。为了应对这一挑战，需要对沼气和生物合成气燃烧的基本物理和化学过程有很好的了解。在基础研究的基础上，本项目旨在通过综合建模和实验研究，对燃料可变性这一重要问题有一个透彻的了解。这项研究具有学术、环境、社会和潜在的经济影响。兰开斯特大学和谢菲尔德大学的这个联合项目旨在为沼气和生物合成气燃烧开发现实和预测的物理化学模型，并将燃烧和排放特性与燃料组成之间的映射关系用于可再生气体燃料的清洁能源利用。基于严格的建模和实验，该项目将提供对沼气和生物合成气利用的透彻了解，突出不同成分的影响。该项目旨在更好地了解生物能源利用的复杂物理化学过程，从而推动生物能源技术的部署。该项目由四个相互关联的工作包组成：(1)WP1：开发化学动力学机制，其中将开发和优化一系列沼气和生物合成气燃烧的动力学机制；(2)WP2：沼气和生物合成气燃烧的大涡模拟，其中将使用先进的湍流燃烧模型进行燃料变化影响的参数研究；(3)WP3：沼气和生物合成气燃烧的实验，其中将系统地进行先进的燃烧诊断；和(4)WP4：验证、整合和优化，其中将制定关于不同成分的沼气和生物合成气的利用指南。
