No full textA Code for the Preliminary Design of Cooled Supercritical CO2 Turbines and Application to the Allam Cycle
No full textThis paper documents a thermo-fluid-dynamic mean-line model for the preliminary design of multistage axial turbines with blade cooling applicable to supercritical CO2 turbines. Given the working fluid and coolant inlet thermodynamic conditions, blade geometry, number of stages and load criterion, the model computes the stage-by-stage design along with the cooling requirement and ultimately provides an estimate of turbine efficiency via a semi-empirical loss model. Different cooling modes are available and can be selected by the user (stand-alone or combination): convective cooling, film cooling, and thermal barrier coating. The model is applied to attain the preliminary aero-thermal design of the 600 MW cooled axial supercritical CO2 turbine of the Allam cycle. Results show that a load coefficient varying from 3 to 1 throughout the machine, and a reaction degree ranging from 0.1 to 0.5 lead to the maximum total-to-static turbine efficiency of about 85%. Consequently, as opposed to uncooled CO2 turbines, a repeated stage configuration is an unsuited design choice for cooled sCO2 machines. Moreover, the study highlights that film cooling is considerably less effective compared to conventional gas turbines, while increasing the number of stages from 5 to 6 and adopting higher rotational speeds leads to an increased efficiency

No full textThis study aims at estimating the energy and environmental performances of a new cogenerative configuration of the waste to energy (WTE) plant in Piacenza. At present, the plant is authorized to treat 120,000 t/y of waste, but this limit does not represent the full treatment capacity of the facility. To exploit the plant potential and, at the same time, to reduce total equivalent emissions of the WTE process, a cogenerative configuration has been proposed. In this new scenario a back pressure turbine would be installed in parallel to the existing one, in order to supply heat to the district heating network of Piacenza and the total amount of waste treated per year by the facility would be increased to 134,100 t. The increase of 14,100 t should be satisfied by industrial and commercial waste, which would otherwise go to landfill. To compare the cogenerative scenario with the current situation, the environmental impact for the two cases has been evaluated by means of a life cycle assessment methodology. The results of the analysis show that the new configuration can ensure significant energy and environmental benefits.</jats:p
