pellets. The results show that there is stronger chemisorption between organic functional groups in MHA binder molecular and specularite particles, improving the green pellet strength. MHA binder has obvious effect on the strength and microstructure of preheated pellets due to the thermal decomposition of organic matters in MHA binder. Appropriately increasing preheating temperature or time can......
J. Cent. South Univ. (2018) 25: 1464-1474 DOI: https://doi.org/10.1007/s11771-018-3840-6 Energy and exergy recovery from exhaust hot water using organic Rankine cycle and a retrofitted.... However, the excess heat carried by EHW is typically ignored and discharged into the environment, resulting in heat loss and heat pollution. An organic Rankine cycle (ORC) is an attractive technology......

溶剂先转变为氧氟化钽(TaO2F)和Ta2O5等中间相; 在1500℃热处理后, Ta全部转变为TaC. 热力学计算表明, C还原Ta2O5生成TaC的温度为1109℃, 与1200℃热处理后TaC的X射线衍射结果一致. 关键词: Ta有机溶剂; C/C复合材料; 热处理 中图分类号: TB332 文献标识码: A Conversion process of Ta organic...) Abstract: C/C-TaC composites with well-distributed TaC particles were made by C/C composites infiltrated with Ta organic solvent and heat treated. The forming process of TaC is characterized by XRD......
300072, China) Abstract: Considering the isentropic efficiency of steam turbine and pump, the theoretical calculation formula of thermal efficiency for the small organic Rankine cycle (ORC) system was deduced. According to the formula derived, the thermal efficiency of four organic working fluids (R134a, R123, R245fa and R227ea) for the small ORC system were calculated under the same condition......
