The Energy Saving Renovation Project of Electric Feed Pump of Liupanshan Thermal Power Generation Plant Awarded the First Prize for the "Technological Achievements of National Power Employees"


Recently, the 2014 (6th session) "Technological Achievements of National Power Employees" prize was formally announced by the National Committee of China Energy & Chemical Engineering Union and China Electricity Council ("CEC"). After the preliminary assessment, reassessment and final review by experts, the "Energy Conservation Renovation Project of Electric Feed Pumps" for the Liupanshan Thermal Power Generation Plant, which was implemented by Guangzhou Zhiguang Energy-saving Co., Ltd. ("Zhiguang") for CHINA ALUMINUM NINGXIA ENERGY GROUP CO., LTD., was awarded the first prize for the "Technological Achievements of National Power Employees". It was also the only project winning such prize in the electrical engineering field.

After completion of such renovation project, Unit #2 of this plant had a year-round operation duration of 7,900 h, among which 5,960 h was available. Its average annual load rate was up to 75%. The frequency converter renovation of two feed pumps led to the annual power saving of 1,795 kWh, equivalent to 5,745 t standard coal. The power saving rate was 26%, equivalent to approx. 1% (330 MW, 100 ECR) reduction in the plant power consumption. Such integrated energy conservation renovation project of variable-speed feed pumps with hydraulic couplers for boilers complied with national development policies for this industry. It was conductive to energy conservation and emission reduction and also achieved good economic benefits.
Zhiguang's such project winning the first prize for the "Technological Achievements of National Power Employees" (6th session) in 2014 highlighted its cutting-edge technologies and global leading role in the field of electric feed pump system renovation. As a pioneer and professional leader in this industry, Zhiguang provided integrated solutions for hydraulic, oil and electrical engineering and control regarding such energy conservation renovation of electric feed pumps for boilers in thermal power plants. It had unique proprietary technologies, renovation approaches and abundant experience in testing. In 2014, Zhiguang has made a major breakthrough in the field of integrated energy conservation renovation for coal-fired power plants. Its energy conservation project of the domestic first electric feed pump has passed the scientific and technological achievement appraisal in this industry. Its overall technology has been up to the international advanced level. For this project, the applications for five national patents have been filed and three have been granted national authorization.
