The invention discloses a novel steam turbine structure. The novel steam turbine structure comprises a stator shell, wherein a sealing cover is arranged at an opening of the stator shell. A rotating main shaft is arranged between the stator shell and the sealing cover, and a fan wheel is arranged outside the main shaft. A plurality of fan blades are formed outside the fan wheel, nozzle mounting sleeves for mounting nozzles are disposed at the stator shell, and the nozzles push the fan wheel to rotate. According to the novel steam turbine structure, the installation of the main shaft is realized through a deep groove ball bearing, an angular contact bearing I and an angular contact bearing II in a mounting sleeve, the sealing and buckling of the stator shell are realized through the sealingcover, the installation of the nozzles is realized through the nozzle mounting sleeves, the nozzles blow the fan wheel on the main shaft to convert gas into mechanical energy, and the energy utilization rate is improved by the outer wall of the fan wheel, a back plate, the inner wall of the sealing cover and closed gas storage cavities formed between every two fan blades. The novel steam turbinestructure can greatly improve the utilization rate of gas work conversion, and is convenient to install and easy to popularize.
