＜正＞The layer of the sintering cooling process is a typical packed bed,in which air flow through the sintering *** voidage distribution in packed beds has relationship with the flow pattern and characteristics of heat transfer in gas-solid ***,it is difficult to measure the voidage of sinter layer in the sintering cooling *** this paper,a new cross-section image analysis method is used to measure the voidage of sinter ores in different standpipes under the laboratory *** results show that voidage changes slightly as the particle size varies,and the height of the standpipes was considered to be a constant in the *** voidage increases as the diameter of standpipes increase（parabolic growth pattern）,finally,a fitting curve between voidage and the diameter of standpipes is given in the *** results are good for designing the waste heat recovery in the industrial practice.

研究了表面涂覆ＣｅＯ２对Ｃｏ４０Ｃｒ合金在１０００℃、空气中恒温氧化和循环氧化的影响。并用扫描电镜／能谱（ＳＥＭ／ＥＤＸＳ）、电子探针（ＥＰＭＡ）、高分辨电子显微镜（ＨＲＥＭ）等测试手段对氧化膜的形貌和成分进行了观察分析。此外，还用声发射（ＡＥ）方法对氧化膜在热应力作用下发生的开裂和剥落进行了监测。结果表明，涂覆ＣｅＯ２后极大地提高了合金的抗恒温氧化和抗循环氧化性能。研究表明，涂覆的ＣｅＯ２主要以细小颗粒的形式高度弥散存在于氧化膜的外表面，并且主要分布于氧化物晶界上，其中部分ＣｅＯ２以更加细小（１０～２０ｎｍ）的形式存在于Ｃｒ２Ｏ３晶粒内部。这些弥散分布的ＣｅＯ２颗粒改变了Ｃｒ２Ｏ３氧化膜的生长机制，通过阻碍Ｃｒ３＋阳离子向外扩散，降低了氧化膜的生长速率，细化了氧化膜的晶粒并提高了膜的高温塑性。

Experimental Study on Characteristics of MSW Pyrolysis Gas

7th World Congress on Recovery, Recycling and Re-integration

作者： Hanqiao Liu, Jiuju Cai SEPA key laboratory on Eco-industry, Northeastern University, P.O Box 345, shenyang, Liaoning, china Xiangjun Bao Shougang Technical research institute, Beijing, china

Based on metallurgical coking technology, a new interlayer pyrolysis system of municipal solid waste (MSW) is put forward by combining out-heating pyrolysis technology with regenerate combustion technology. The system has such advantages as quit innocuity, little secondary pollution and high recycling efficiency. There is certain requirement for the quantity and quality of the pyrolysis gas to supply the energy for maintaining the reaction temperature of the pyrolysis system. To provide reasonable operating conditions of the system, experiments were carried out in a homemade indirect resistance furnace (20 kW). 1 kg sample consisting of vegetable, plastics, paper and woods as typical components of MSW was used The effects of process conditions including temperature, heating rate, moisture and amount of blending coal on pyrolysis gas characteristics such as yield, composition and calorific value were studied. Some conclusions can be drawn from the experimental results: (1) In pyrolysis of MSW, the gas yield increases with final pyrolysis temperature increasing. High heating rate favors cracking of the hydrocarbons in gaseous products, and thus increases the content of H2, (2) There is a prominent influence of the moisture of MSW on pyrolysis gas. The lower the moisture, the higher the yield and the calorific value of recycled gas, (3) The pyrolysis time is shortened when the amount of blending coal is increased because it increases the bed porosity, improving the heat transfer. The blending coal can also improve the stability of gas products

采用电化学噪声技术,结合电化学阻抗谱及极化曲线测量,研究了峰时效AA2195-T8铝合金在3.0％NaCl溶液中的腐蚀电化学特征.结果表明,腐蚀初期,合金表面钝化膜上不断有孔核的形成与修复,并导致阻抗谱上感抗成分的存在.随腐蚀时间的延长,其感抗成分消失且阻抗模值降低.阳极极化时,由于其孔蚀电位与自腐蚀电位接近,钝化电位区间很小;随腐蚀时间的延长,极化电阻先增加而后减小,自腐蚀电流则呈相反趋势变化.

The function that carbon fiber reinforced polymer(CFRP)bonded extemally to prevent effectively chloride ions from diffusing into concrete is confirmed by 2 groups of laboratory accelerated penetration *** effectiveness of CFRP material to prevent Cl is confirmed by tests of 1group;and similar conclusion also is drawn in 2groups of test for CFRP externally bonded on concrete ***,for coastal concrete structures,there is not only strengthening function of bonding CFRP,but also that of preventing chloride ion from penetrating into concrete,and consequently to prolong the initiation period of rebars *** is also confirmed by test that there is similar function of CFRP and coating on the surface of concrete to shield concrete against chloride ***,it is suggested that CFRP bonded externally and coating or other surface protection measures are applied jointly to form an integrated surface prevention system when CFRP is applied in strengthening coastal concrete structures. Considering the limitation involving with time of the effective shielding function of CFRP,an equation used for residual lifetime prediction of concrete structures bonded externally with CFRP is derived from Fick’s diffusion ***,the conclusion may be used for recommendation when CFRP is applied to strengthen coastal concrete structures.
