This data set describes a biomass boiler with a capacity of 30MW that is used for the direct combustion process to generate electricity. The primary fuel for generating the 10,000 kWh of electrical energy is straw, with a consumption rate of 1.4 kg/kWh. This process is typically utilized in power plants that use renewable biomass resources to produce electricity for a variety of applications, such as residential, commercial, or industrial energy supply. When utilizing this data set for Life Cycle Assessment, consider integrating it within the energy supply chain, especially focusing on biomass energy production. Attention should be paid to regional differences in straw availability and quality, which can impact the overall efficiency and emissions of the process. Users should also consider the end-of-life processes for the biomass infrastructure, potential emissions from straw procurement and transportation, and any energy inputs required during the operation of the biomass boiler. Ensure that these parameters are consistently applied in the LCA model to avoid misinterpretation.
