en.Wedoany.com Reported, On March 24, the #1 and #2 units of the Kailin Fertilizer Steam Energy Efficiency Comprehensive Utilization Project, contracted by Guizhou Donghua Engineering Co., Ltd., a subsidiary of China National Chemical Engineering (CNCEC) Donghua Company, successfully achieved steam integration and grid-connected power generation.
The project is located in the Xiaozhaiba Industrial Park, Xifeng County, Guiyang City, Guizhou Province. It involves the construction of two sets of turbine generator units, each with an installed capacity of 2500kW, along with ancillary facilities. By installing a bypass at the steam pressure and temperature reduction point of the phosphoric acid concentration process and replacing the pressure/temperature reduction device with a turbine generator, the project converts high-temperature, high-pressure steam into low-temperature, low-pressure steam for the process steam system after power generation, thereby improving energy efficiency by saving steam and electricity.
The steam integration and grid connection operations were strictly carried out according to the established plan and safety procedures. During the commissioning period, the #1 and #2 units operated stably, with power generation output exceeding design parameters, and all systems demonstrated good regulation performance. Upon full operation, the project will significantly enhance the comprehensive energy utilization level of the phosphoric acid concentration unit, providing strong support for the goals of energy conservation, consumption reduction, and green, low-carbon development.
In the next step, the project team will organize participating construction units to complete subsequent rectification, performance assessment, and other milestone tasks, striving to win the battle for project handover and lay a solid foundation for project completion.
