The sludge and bituminous coal co-combustion power generation process and the sludge and rice straw co-combustion power generation process are the actual operation cases of a sludge co-combustion co-combustion power generation company in Kunshan, which uses the plant's 45 t/h circulating fluidized bed boiler and is equipped with a 6 MW back-pressure generator set. Users who apply this dataset for Life Cycle Assessment should carefully consider the specific technological and geographical context of the process, ensuring that methodological assumptions such as system boundaries and allocation methods are consistent with their study's goals. Users should account for regional differences that may affect emissions and resource consumption. Additionally, users must adjust for any discrepancies between the functional unit of this process (1 tonne of 65% moisture content wet sludge) and their study's functional units. Attention should be paid to the potential emissions associated with co-incineration and the relative proportion of sludge to coal used in the process.
