特殊场合下的温度测量技术

对于测量条件恶劣，不能用常规传感器实现的特殊场合，如高温强腐蚀性介质、真空、高温熔体及核辐射条件下的温度测量，必须开发特种专用传感器。本文阐述了钨铼热电偶等特种温度传感器的特点、性能及应用，并着重探讨了当前测温领域热点问题。铝液、铜液及熔盐等高温溶体连续测温；高温渗碳、真空粉末治金烧结炉(气)等强还原性气氛下的温度测量：流化床等流动粉体等高温强磨损条件下的温度测量技术等。实践证明，新开发的特殊场合下专用温度传感器，不仅与国际接轨，替代进口产品，而且还可以打入国际市场。

Mineralogy of clean coal combustion by-products

Coal combustion technologies are changing in order to burn coal more cleanly. Many “clean combustion“ and postcombustion technologies are developed to remove SO2 and NOx gases, particulate matter during combustion, or from the flue gases leaving the furnace. This paper focuses on three types of fly ash (flue gas desulfurization (FGD) residuals, atmospheric fluidized bed combustion (AFBC) residuals and sorbent duct injection (SDI) residuals) which produced by “the clean combustion“ and postcombustion technologies. The residuals formed by FGD are PCFA (pulverized coal fly ash) grains entrained with reacted and unreacted sorbent and have lower bulk densities than PCFA grains because it contains higher concentrations of calcium and sulfur, and lower concentrations of silicon, aluminum and iron than PCFAs. AFBC residuals consist of spent bed which is a heterogeneous mixture of coarse-grained bed material and irregularly shaped, unfused, spherical PCFAs. The main crystalline phases in AFBC residuals are anhydrite (reacted sorbent), quartz and lime (unreacted sobent), calcite, hematite, periclase, magnetite and feldspars.The residuals produced by SDI contained 65%-70% PCFA with the larger sizes material being irregularly shaped, fused or roughedged. The reaction products of sorbent (portlandite and lime) included calcium sulfate (anhydrite) and calcium sulfate. The chemical properties of these residuals are similar to those of high calcium PCFAs because of the high alkalinity and high pH of these residuals.

珠江三角洲典型区域土壤重金属污染探查研究

以珠江三角洲典型区域研究高强度经济开发下土壤环境中重金属污染的状况。测定了84份样品中铜、锌、镉、铬、铅的含量水平。土壤中镉、铬、铅、镍、铜、锌的含量分别在0.166～0.433mgkg-1、2.28～94.28mgkg-1、20.36～143.3mgkg-1、2.29～63.55mgkg-1、4.8～65.1mgkg-1、10.06～131mgkg-1之间。从分析结果可以看出,镍、铅等元素在有些地方普遍偏高,且有的极为明显,已高出背景值108.3mgkg-1。其他元素也存在不同水平的富集,普遍高出背景值。     

克拉2气田异常高压特征及成因

克拉2气田异常高压的主要特征是：异常高压储层的顶部存在下第三系巨厚的盐岩、膏泥岩盖层,封闭性能良好;含气面积大,储量高;断层对气藏的形成和保存起关键作用。本研究区异常高压形成的主控因素是构造抬升和水平构造挤压应力。喜山晚期构造运动导致地层大幅抬升,遭受剥蚀而垂向、侧向上良好的封闭性使得孔隙流体压力得以保存;侧向挤压应力又加剧了异常高压的程度。

Comprehensive Utilization of Complex Titania Ore

 To fully utilize Panzhihua titanium resources, a new process was proposed. In the process, Panzhihua ilmenite concentrate was first reduced in a rotary hearth furnace (RHF) to produce a titanium rich material and iron. The titanium rich material was then used in a new chlorination process to produce TiCl4. The comparison of different groups of experimental results or calculation results showed that the utilization ratio of material was improved by using the titanium rich material after pretreatment other than low level titanic ilmenite directly and the combined fluidized beds (FTF) were more likely to reduce bed height and reaction time than the single fluidized beds (Single F or Single T) under the condition of the same chlorination conversion ratio. Finally, the influence of reduction temperature and the anti agglomeration capacity of the combined fluidized bed was analyzed.
