Recently, the waste heat utilization project designed, supplied and commissioned by Boxu New Energy for Zhejiang Rongxiang Heating Co., Ltd. has been successfully put into operation! The project innovatively integrates three core subsystems: high-pressure flash evaporation system, saturated steam turbine power generation system, and ORC (organic Rankine cycle) power generation system, and builds an efficient and complex power energy station, marking an important breakthrough in the field of deep utilization of industrial waste heat and resource recovery.
Live shooting
Efficient collaboration, turning waste into treasure
The core process of the project lies in the cascade energy recovery of waste heat:
High-pressure flash evaporation: 14MPa, 298°C high-pressure condensate enters the flash evaporation system, and instantly produces saturated steam with a pressure of 1.1MPa and a temperature of 185°C.
Steam turbine power generation: The saturated steam generated drives a high-efficiency saturated steam turbine unit to generate electricity.
ORC re-power generation: The waste heat contained in the remaining 1.1MPa and 185°C saturated water after flash evaporation further drives the ORC generator set to conduct deep power generation and realize the "dry and clean energy".
Excellent performance and efficiency leadership
Even when the owner's total heat load is only 50%, the system has shown excellent operating performance: the measured efficiency of the saturated steam turbine unit is more than 76%, and the measured efficiency of the reactionary axial flow ORC generator set is more than 80%. Such impressive data lays a solid foundation for the project to achieve higher efficiency goals at full capacity, and all parties are full of confidence.
Execute efficiently, get it right the first time
Fast installation: Boxu New Energy's technical team provided professional guidance throughout the process, and efficiently completed the mechanical installation and commissioning of the flash system, steam turbine system and ORC system in only 50 days.
Perfect joint commissioning: In the system joint commissioning stage, Boxu New Energy engineers worked side by side with partners to overcome many technical challenges, working day and night, and finally ensured that the three sets of subsystems were successfully connected to the grid for the first time, demonstrating strong technical strength and project execution.
Linkage debugging
Significance: Green power, double value
The successful operation of this project lies not only in the construction of a technically complex integrated power power station, but also in its dual core missions:
Deep waste heat utilization: Efficiently converts high-grade thermal energy into valuable electrical energy, significantly improving the energy utilization efficiency of enterprises.
The key to resource recycling: The project has successfully achieved temperature and pressure reduction of condensate while high-efficiency waste heat utilization, creating necessary conditions for the safe reuse of high-quality demineralized water, and has significant environmental protection and economic value.
The success of Zhejiang Rongxiang Thermal Waste Heat Utilization Project is a strong proof of Boxu New Energy's comprehensive strength in the field of complex energy system integration and efficient waste heat power generation technology. The project provides innovative solutions and successful examples for the industrial field to achieve cascade utilization of energy, energy conservation and emission reduction, cost reduction and efficiency increase. Boxu New Energy will continue to innovate to help customers create greater green value!
