On October 17th, Xinran ORC organic Rankine screw expansion generator sets were exported to the Middle East to assist in geothermal power generation projects. Xinran ORC organic Rankine screw expansion generator sets are devices that utilize medium and low-temperature waste heat (80°C-300°C) to generate electricity by converting thermal energy into electrical energy through a screw expander. This technology is efficient and stable, and is suitable for various scenarios such as industrial waste heat and geothermal energy.

10月17日，信然ORC有机朗肯螺杆膨胀发电机组出口（Middle East）中东助力地热发电项目。信然ORC有机朗肯螺杆膨胀发电机组是一种利用中低温废热（80℃-300℃）进行发电的设备，通过螺杆膨胀机将热能转化为电能。该技术具有高效、稳定的特点，适用于工业余热、地热等多种场景。

Working principle: Organic working fluid (such as R245fa) is used as the medium to achieve the conversion of thermal energy into mechanical energy through evaporation, expansion, and condensation cycles. Hot fluids (waste steam, flue gas, etc.) enter the evaporator to heat the working fluid, generating high-pressure steam that drives the screw expander to do work. Finally, the heat is released through the condenser to complete the cycle.

工作原理：采用有机工质（如R245fa）作为媒介，通过蒸发、膨胀、冷凝循环实现热能到机械能的转换。热流体（废蒸汽、烟气等）进入蒸发器加热工质，产生高压蒸汽推动螺杆膨胀机做功，最终通过冷凝器释放热量完成循环。
