Agro-residue is one of the important biomass resources in China and its efficient utilization is crucial for providing bio-energy, releasing risk of environmental pollution, and enhancing rural incomes. Densification is one of the important utilization routes of agro-residues. The objective of this paper is to explore the development of agro-residue densified fuel in China based on energetics analysis. The energetical property and energy potential of main agro-residues in China were firstly analyzed and then the development of agro-residue densified fuel in every region was evaluated based on energetics analysis. The results show that the main agro-residues in China are good feedstocks as densified fuel and they constitute enormous energy potential for developing densified fuel. However, the situation of every region should be considered for the development of agro-residue densified fuel. The primary energy embodied per unit of useful energy indicates that most of the regions in China are suitable for developing agro-residue densified fuel as it is energetically advantageous compared with coal, whereas only about 25% of regions near coal production locations are not suitable as they are less energetically advantageous.
农业残留物是中国重要的生物质资源之一，其高效利用对于提供生物能源、释放环境污染风险和提高农村收入至关重要。浓缩是农业残留物的重要利用途径之一。本文旨在基于能量学分析探讨中国农业残留物浓缩燃料的发展。首先分析了中国主要农业残留物的能量学特性和能量潜力，然后基于能量学分析评估了每个地区农业残留物浓缩燃料的发展情况。结果表明，中国的主要农业残留物是作为浓缩燃料的良好原料，它们构成了开发浓缩燃料的巨大能源潜力。然而，对于农业残留物浓缩燃料的发展，应考虑每个地区的情况。单位有用能量所包含的初级能源表明，与煤炭相比，中国大部分地区都适合开发农业残留物浓缩燃料，因为从能量角度来看具有优势，而只有约 25%的靠近煤炭生产地的地区不适合开发，因为从能量角度来看不具有优势。
