由于地理、用户使用条件和峰段要求的限制，LNG槽车在输送天然气方面有着巨大的市场需求，是管道输配的重要补充手段。LNG槽车往往需要在没有机械动力的情况下，依靠配套的增压汽化器提供压力源，采用顶部气相空间加压方式卸载液体。槽车常配用的汽化器有空温式汽化器和水浴式汽化器两种形式，空温式汽化器使用空气作为热源，节约能源，操作费用低廉。对于长江三角洲地区，常年气候温和湿润，最低气温在零度以下的天数屈指可数，使用空湿式气化器完全满足生产要求。文章介绍LNG槽车自增压空温式汽化器的设计计算，其中包括天然气气相和液相物性的计算方法，以及空温式汽化器的热力计算。然后给出空温式汽化器的换热面积和结构尺寸等设计参数。

Effect of Fe2O3 addition on consolidation and properties of 8 mol% yttria-stabilized zirconia by high-frequency induction heated sintering (HFIHS)

Dense nanophase 8 mol% yttria-stabilized zirconia was sintered by high-frequency induction heated sintering (HFIHS) within 6 min from 8YSZ nanopowder prepared by co-precipitation method. Sintering was accomplished under the combined effects of an induced current and mechanical pressure. Highly dense 8YSZ with relative density of up to 96% was produced under simultaneous application of a 60-MPa pressure and the induced current. The effects of Fe₂O₃ additions on the sintering behavior, mechanical properties and ionic conductivities of the 8YSZ were investigated.

有机热载体炉设计中常见问题的探讨

文章着重对有机热载体锅炉结构型式的选择、受热面的布置,以及工艺流程等作了阐述。对于大容量加热炉应考虑布置尾部受热面,不仅是为了提高锅炉的热效率,同时对引风机的使用寿命大有益处。对受热面布置,应考虑到介质的流动方向。“低进高出”更有利,即低温导热油从锅炉的最低点输入,加热后的高温导热油应从锅炉的最高点输出,有利于导热油的脱水排汽。     

Growth and dielectric properties of Ta_2O_5 single crystals grown by laser heated pedestal growth technique

Ta2O5 single crystals have been grown by the laser heated pedestal growth (LHPG) technique up to several centimeters length with diameter of 1.1 mm. The crystal, characterized by X-ray diffraction, dielectric measurement, and thermal expansion analysis, has Htri-Ta2O5 symmetry. Dielectric permittivity, loss tangent along [001] and [110] direction were investigated over the temperature range from -80 ℃ to 100 ℃. Large dielectric anisotropy in Ta2O5 single crystal was observed. At room temperature, the dielectric permittivities (1 MHz) along [001] and [110] are 33.2 and 231.9, respectively. The reason of dielectric enhancement in Ta2O5 crystal grown by LHPG was also discussed.     

加热非燃烧状态下烟草制品的TSNAs释放规律

为了解加热非燃烧烟草制品加热时TSNAs的释放情况,以烟草薄片颗粒（RTPs）为原料,研究甘油含量、加热温度等对TSNAs释放的影响,并探究了其中NNN与NNK释放之间的关系。NNK和NNN释放量随加热温度升高而增加,达到240℃之后增量变小;NAB的释放量随温度升高不断上升;NAT的释放量先随温度升高而增加,达到240℃后基本稳定。同时,原料中添加甘油会不同程度地减少TSNAs的释放量。因此,烟草薄片颗粒中的甘油含量、加热温度显著影响TSNAs释放行为,合理的甘油含量和低温加热均可有效减少TSNAs的释放。原料中添加NNN后,NNK的释放量显著增加,推测原料中NNN含量增加可能促进气溶胶中NNK的释放。
