在能源轉換的精密舞臺上，燃氣發電機組扮演著將化學能轉化為電能的魔術師角色。當每立方米天然氣在氣缸內迸發能量時，僅有約40%的能量被轉化為電能，其余則以熱能形式散失。提升這看似微小的百分比，成為工程領域永恒的追求。這場效率革命，需要從燃燒控制、熱能管理到系統集成的全鏈條創新。

　　On the precise stage of energy conversion, gas generators play the role of magicians in converting chemical energy into electrical energy.

Improving this seemingly small percentage has become an eternal pursuit in the field of engineering. This efficiency revolution requires full chain innovation from combustion control, thermal energy management to system integration.
