A boiler design method and system for a supercritical carbon dioxide unit, and a storage medium are provided. The boiler design method includes the following steps: step 1, determining a boiler type, known design parameters and unknown design parameters of boilers to be designed; step 2, acquiring operating parameters of each selected supercritical carbon dioxide unit respectively, and establishing a relational expression among a plurality of operating parameters in the operating parameters of each supercritical carbon dioxide unit respectively; and step 3, substituting the known design parameters in step 1 into the relational expression determined in step 2, and calculating the unknown design parameters. The operating parameters of the boilers, with the optimal performance, of the supercritical carbon dioxide unit are selected to establish the relational expression, and the determined operating parameters are substituted into the relational expression to calculate design parameters to be determined.
