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.

生物量气化的沼气和生物合成形式形式的气态可再生生物能源由于燃料性能的可变性能和相应的可变燃烧性能而面临其利用中的主要问题。 CH4浓度的巨大变化会导致强烈的燃料变异性效应。对于生物质的气化产物的清洁剂生物同伴，燃料可变性的问题同样重要。有了可变的燃料混合物，人们担心燃烧效率/稳定性以及污染物的排放。为了应对这一挑战，需要对沼气和生物同步的燃烧的潜在物理和化学过程有很好的了解。基于基本研究，该项目旨在通过综合建模和实验研究对燃料可变性的重要问题进行彻底的了解。这项研究具有学术，环境，社会以及潜在的经济影响。这是兰开斯特大学和谢菲尔德大学之间的联合项目，旨在开发现实和预测的物理化学模型，用于沼气和生物同步的燃烧以及燃烧和排放特征之间的生物同步和映射，以使能源特征与燃料的燃料组成，以使清洁能源从可腐烂的Case fuuels中使用。基于严格的建模和实验，该项目将对沼气和生物同步的利用进行透彻的了解，从而强调可变组成的影响。该项目旨在更好地了解生物能利用的复杂物理化学过程，该过程可以将生物能源技术推向部署。该项目由四个相互连接的工作包组成：（1）WP1：化学动力学机制的开发，其中biogas and Biogas and Bioogas and BeioSyngas and Beogas and Beogustiion范围是（2）WP2：沼气和生物联合燃烧的大涡模拟，其中将使用先进的湍流燃烧模型对燃料可变性效应进行参数研究； （3）WP3：沼气和生物合成燃烧的实验，在该实验中，将系统地进行先进的燃烧诊断； （4）WP4：验证，集成和优化，其中将得出有关沼气和具有不同组成的生物同步的指南。
