AI Technical Summary

⚠Technical Problem

When the gas pressure in the existing gas storage device is lower than the rated inlet pressure, the efficiency of the high-voltage module decreases, which limits the power generation time of the air turbine and causes a blower phenomenon, affecting the power generation efficiency.

⚗Method used

It employs components such as a single-flow ultra-high pressure cylinder module, a single-flow high pressure module, a single-flow medium pressure module, a dual-flow low pressure module, an ultra-high pressure thrust support combined bearing, a high pressure thrust support combined bearing, a self-meshing clutch, an ultra-high pressure valve group, and a high pressure valve group. By controlling the intake air volume and speed, it achieves four heating cycles and three reheat cycles, extending the efficient operating time of the air turbine.

🎯Benefits of technology

By extending the power output time of the air turbine within a limited volume, ensuring high efficiency of each cylinder, continuous high-power operation is achieved, and the power generation efficiency of the air turbine is improved.
