Scientific Research Instruments and Equipment

R&D platform on distributed energy system, supported by the National Energy Administration, was constructed and passed examination. The R&D platform consists of small scale power generation subsystem, solar thermal chemical power generation subsystem, cogeneration of power and cooling driven by surplus heat subsystem, which will support the researches on mutual beneficial use and cascade use of energy.

The experiment platform for the complementation utilization of the concentrated solar energy is developed, and the measurements of the solar energy resource, the optical focusing system parameters, and the key parameters in a receiver/reactor coupling the heat transfer and chemical reaction are achieved. The 300 kWt wide-range PTC experimental platform has been established and run; the 30 kWt PTC with variable mirror area has been established; the single DSG tube experimental rig has been established.

A 10 kWth CO2 enrichment experimental platform was developed (1200°C, 6 MPa). An experimental equipment combining coal gasification and chemical looping combustion was also developed. A gas analyzer Agilent Miro 490Pro was added to lab.

A Zeiss Scanning Electron Microscope (SEM; Model Merlin Compact) was installed and put into use. The maximum resolution is 0.8 nm, and maximum magnification is 2 million times. It’s mainly used for accurate measurements and analyses on chemical composition and microstructure of magnetic metal oxide material with high resolution observation, and for studying physical, chemical properties and microstructural change of such materials under various temperature and reaction conditions.

Major Projects

This year we've successfully taken 4 national-grade major science and technology projects and sub-projects. 3 projects belong to the following national key research and development plans, “Multi-Energy Hybridization and Comprehensive Cascade Utilization of Energy of the Distributed Energy Systems”, “Key Fundamental Scientific Research on CO2 Capture with Low-energy Penalty, Storage and Utilization”, and “Energy Conversion and Cascade Utilization of Energy in the Novel Thermodynamic System”, respectively. 1 project belongs to NSFC-funded major project "Fundamental Researches of EnergyTransfer and Conversion in Solar Energy Utilization".

Major Achievements in 2016

In distributed energy system direction, the distributed energy system project supported by the 13th National Five-year Plan on research and development emphasis was approved and started. Funded by this project, the researches on mutual beneficial use of multi-type of energy and cascade use of energy will make breakthroughs. A new method integrated air dehumidification and desalination driven by surplus heat was invented. A combined power, cooling, and dehumidification system was developed and passed auditing successfully. The key technology researches on solar thermo chemical power generation, cogeneration of power and cooling driven by surplus heat, and absorption heat transformer were promoted.

On the solar thermo chemical and the thermal power generation system integration, a mid-and-low temperature solar thermal power generation prototype (100 kWe) with stable operation is firstly created, the orderly transformation ways of fuels and new approaches of the complementation utilization of multiple energy resources are developed. The MWe class distributed energy system with the multiple energy complementation utilization pattern is created, and "source energy saving" and "source energy storage" in the distributed energy system are achieved. Advanced solar complementation system technologies with independent intellectual property rights and original innovations are obtained, which will contribute to future industrial applications and technology promotions. Development has been achieved in the study of system integration and active operation strategy optimization for solar-aided coal-fired power generation system. In theoretical studies: The wide-range active sun-tracking operation strategy has been proposed considering all latitudes and all year round conditions, especially for the specific weather conditions in China; In experimental studies: Based on the 300kWt wide-range PTC experimental platform, a large amount of data has been acquired from long-time running under trans-season conditions, covering various weathers. The theoretical predictions have been verified by the experimental data, which indicates a very promising future for the extensive application of this technology.

In greenhouse gas control and multi-generation direction, research was focused on greenhouse gas emission reduction technologies, including gasification by decomposition of coal, chemical looping combustion, low-energy-penalty CO2 capture and poly generation technologies. Energy saving mechanism, experiments and system integration were presented and investigated for the above technologies. In 2016, we acquired a project supported by the State's Key Project of Research and Development Plan. Two USA patents of the original coal gasification technologies were authorized. And an important research result about coal to alternative fuels was published on Nature Climate Change in March, 2016.
