On March 17, China National Solar Thermal Energy Alliance organized expert team to carry out site inspection and qualification assessment for Beijing CSP Engineering Laboratory of Rayspower Energy Group Co., Ltd.This Laboratory applied for joining public CSP technology (solar heat collection) service platform of the Alliance. Assessment experts include researcher Li Jin of Institute of Electrical Engineering, Chinese Academy of Sciences, Vice-general Manager Na Mingliang of Consumer Products Services Division of China General Certification Center in Beijing, and Vice-Chief Engineer Wang Li of China Building Material Test & Certification Group Co., Ltd.
Assessment expert group firstly listened to application report of Rayspower related to joining into public technology service platform of Solar Thermal Energy Alliance (solar thermal power generation, light condensation, and solar collecting technology); later, the group carried out site inspection for Beijing Engineering Laboratory of solar thermal power generation, light condensation, and solar collecting system technology of Rayspower and also conducted question communication; in their opinion: 3D photogrammetry system of trough collector, mirror-reflection test system, test system for reflector reflectivity, performance test system for high-temperature fused salt material, and laser-tracking commercial measurement system declared by Rayspower meet basic technical requirements of public technology service platform of Solar Thermal Energy Alliance and also possess corresponding detectability; therefore, it is suggested to bring them into public technology service platform of Solar Thermal Energy Alliance.
At this time, there are 5 items in total which are applied by Rayspower for joining into public technology service platform of the Alliance, and they are part of Beijing Engineering Laboratory of solar thermal power generation, light condensation, and solar collecting system technology of Rayspower Energy Group Co., Ltd. This Laboratory is the first engineering laboratory in Beijing which is related to solar thermal power generation, light condensation, and solar collecting system technology approved by National Development and Reform Commission in Beijing, and it was accepted in December, 2016. It is learned that the indoor part of this Laboratory covers an area of 1138 square meters. Under this Laboratory, there are thermotechnical and material laboratory, optic test system laboratory, mechanical structure laboratory, automatic control system laboratory, comprehensive laboratory as well as Changping photothermal experimental base and Yanqing photothermal experimental base which mainly focus on research and development related to photothermal innovation and comprehensive utilization of solar energy.
The assessment expert group suggests Rayspower further improve such contents as the test items and technical index accuracy of all test platforms and further standardize and establish the relevant management system as public technology service platform.
The public technology service platform of China Solar Thermal Energy Alliance relies on the existing experimental detection platform of member organizations of the Alliance and it will be included in the resource database of the Alliance. These public technology service platforms can not only integrate the existing power, but also avoid the waste due to repeated investment in the same or similar projects to realize the maximization of resource benefits. At present, with the identification of public service platform, Solar Thermal Energy Alliance has been equipped with the fast detector for surface accuracy of reflector, movable detector for surface accuracy of trough solar collector, mirror surface measuring instrument of coordinate machine, specular reflectance measuring instrument, platform for weathering resistance performance test of materials, platform for heat loss detection of trough heat-absorbing tube, platform for optical efficiency of trough heat-absorbing tube, detector for energy flux density of trough solar collector, detector for energy flux density of solar furnace, platform for steady-state thermal performance detection of trough solar collector, tester for tracking accuracy of heliostat, platform for performance detection of heat reservoir and heat storage materials, platform for design wind load and wind tunnel test of solar collector, platform for sand-wind abrasion test of reflector and heat-absorbing tube, platform for tracking accuracy and facula characteristic test of tower-type heliostat, platform for electric heat tracing reliability test, platform for heat exchange performance, flowing performance and reliability test of heat exchanger and platform for measuring performance of instruments and etc. Theses platforms will provide support for the development of scientific and reasonable detection standards and provide guarantee for the quality of critical products with solar thermal power generation.
