Customer background: Guizhou Jinyuanxi Hydropower Plant urgently needs to improve its turbine preheating technology due to aging equipment, frequent frequency regulation and peak shaving, increased number of unit starts and stops, long cold start time, and high cost.

Proxy service content: Gain in-depth understanding of the technical details of a thermal power turbine preheating device in power plants, explore technological innovation points, that is, by changing the heating steam source, conventional compressed hot air is replaced with reheated cold section steam from adjacent units to preheat the cylinder. Carefully write utility model patent application documents, highlighting the technical challenges solved by the device and the economic benefits it brings. At the same time, assist the power plant in compiling technical application results into technical reports and case studies, and exchange and share them within the industry.

Achievement: Successfully obtained national utility model patent authorization, significantly reduced start-up costs for power plant units, and significantly improved economic benefits; Technical reports and case studies have attracted attention within the industry, providing reference for similar power plants to solve similar problems.
