| 1 | Investigation of the Evolution Behavior of Light Tar During Bituminous Coal Pyrolysis in a Fluidized Bed Reactor显示文摘The evolution behavior of the light tar fraction of tar during large bituminous coal particle pyrolysis in afluidized bed reactor at 500--900 ℃ was investigated to optimize the industrial process. The coal residence time wasvaried from 30 s to 150 s. The crude tar obtained was distilled and separated into the light fraction and the heavyfraction through an evaporator under conditions of 280 ℃ and 104 Pa. The light tar was subjected to GC-MS analysis,and the 300 main species in each spectrum were determined and analyzed. The experimental results showed that theevolution behavior of the light tar fraction and the heavy tar fraction presented spectacularly different variation trendswith pyrolysis temperature and coal residence time. The molecular weight and number of rings per aromatic com-pound molecule contained in the light tar fraction increased with increasing pyrolysis temperature because of poly-merization. It was also observed that the amount of methyl substituents decreased with an increasing number of ringsper molecule of poly-aromatic ring compounds. The chain aliphatic compound evolution was suppressed and under-went heterocyclization with increasing temperature. | LI Chao FANG Mengxiang XIAO Ping SHI Zhenghai CEN Jianmeng YAN Qike WANG Qinhui LUO Zhongyang | 2016 | Chemical Research in Chinese Universities2016，32，6： | 1 |
| 2 | Supercritical Characteristics of a Relaxation Oscillator显示文摘A relaxation oscillator can be described by two maps:one circle and one inverse circle.The order of map depends on the function form of the modulation signal.Supercritical behaviors of the oscillator were studied experimentally and numerically.Two scaling laws S(f)∝f^(-δ) and τ∝|f-f_(c)|^(-γ) were verified.Both the scaling exponents δ and γ2 increase when the order m getting larger. | JI Feng LIU Hui YANG Zhenghai SHI Kangjie HE Daren WANG Dalcai | 1991 | Chinese Physics Letters1991，8，1： | 0 |
| 3 | Independent Research and Design of 600-MW Supercritical CFB Boiler显示文摘In order to further develop and improve the technologies for large-capacity supercritical CFB boiler, the key technologies for large CFB boiler were systematically studied, based on the development of first domestically-made 210-MW and 330-MW CFB boilers. The scheme of 600-MW supercritical CFB boiler was designed, including the furnace structure, key components, steam-water system and auxiliary systems, which laid a technical foundation for the engineering applications. | Sun Xianbin, Li Zhiwei, Shi Zhenghai, Huang Zhong, Jiang Minhua Xi’an Thermal Power Research Institute Co., Ltd.
