Abstract

In this paper, straw and coal are used as raw materials to produce composite fuel pellets, and the energy consumption and environmental impact of fuel pellets for combustion heating are studied by using the whole-life cycle assessment method. The results show that the total energy input of fuel pellets is 908 MJ/t, the calorific value released by combustion is 15490 MJ/t, and the energy ratio of output to input is 17.1, indicating high energy conversion efficiency. The energy input of fuel pellets is mainly used for corn planting, in which the use of nitrogen fertilizer in the process of planting consumes more energy. The most significant contribution to climate change（GWP） and acidification（AP） is the combustion of fuel pellets, in which the direct contribution of combustion pollutants is the largest, accounting for 53.22% and 46.08% respectively; the most significant contribution to the water resources consumption（WU） is the production of fuel pellets, accounting for 71.56%; the most significant contribution to eutrophication potential（EP） is the discharge of waste residue from pellets combustion, with a contribution rate of 43.40%.
