Jiangsu Pengfei group, the old building materials machinery enterprises which is built in the last century in 80s, mainly engaged in building materials, environmental protection, metallurgy, chemical engineering design, equipment manufacturing, sales, mechanical and electrical equipment supply, installation and commissioning, project contracting and technical services, is China's cement machinery enterprises. In recent years, in the background of high energy consumption and high pollution industry macro-control, the company joined the Tsinghua University and other well-known colleges and universities to carry out the innovation.  "Pengfei" trademark was identified as A Well-Known Trademark in China, Products also won the title of China famous brand. Three years ago,  Jiangsu Pengfei group cooperate with the Chinese Academy of Sciences, and invested 1 million yuan of R & D funds on the development and application of modular mobile waste heat energy storage and utilization technology.

Li Gang, the technology center director of Jiangsu Pengfei Group , said large building materials calcining process system will produce high temperature flue gas emissions, direct air, produce carbon dioxide and sulfur dioxide will not only cause some pollution to the air, will result in a waste of resources. Therefore, Jiangsu Pengfei group join hands to the Chinese Academy of Sciences to try in the field of waste heat recovery and reuse. Now the country has put forward higher requirements for energy saving and emission reduction, we also get inspiration from the field of energy saving and emission reduction to do a series of new technical research, develop some new products. The project, which is working with the Chinese Academy of Sciences, is to keep the heat in the high temperature waste heat stored in new materials and new technologies to make it more efficient.

According to reports, the project help to lay the foundation for the quality and scale of the efficient utilization of waste heat.through finding out the characteristics of cement, heat emission power and high energy consumption enterprises, fluctuation and spatial distribution characteristics; combined with cement, electricity and other high energy consumption enterprises, the characteristics of large temperature fluctuations, finish the preliminary design of heat storage and heat transfer module, numerical simulation and preparation of phase change heat storage material and the development of heat transfer enhancement technology, analyse  the mechanism of multi phase transfer and transfer of heat transfer and heat storage materials in multi-scale structures, find the optimal design scheme of heat storage and heat exchange module; construct the mobile waste heat energy storage and utilization equipment test platform, establish a nonlinear thermal management system in order to realize the dynamic control of waste heat resource; combined with the simulation and experimental results, to further improve the whole set of equipment for the pilot and industrialization of solid foundation.

Li Gang said，this project can be applied to cement plants, power plants, some high energy consumption and high emissions enterprises.  He said, Pengfei group will go on further exploration in the field of energy conservation.” Later, we will cooperate with the Chinese Academy of Sciences derived for other projects, this kind of product can be applied not only in industrial production, but also in civil life. ” (from china building materials)
