2010年土耳其Sanko公司所属的Baztin水泥厂决定拆除旧的湿法窑,兴建一条3000t/d级预分解窑生产线,委托在该国具有多项业绩的德国IKN公司设计,同时提供生产线的主要工艺装备.
由IKN公司制造的预分解窑的生产线的关键主机装备为:
单系列六级低压损Lucy型预热器.塔高110m.生料喂入C1~C2管道,C2~C6预热器直径为Φ7.5m.
在线分解炉高68m,底部宽4.35m,三次风旋流进入.分解炉下部为NOx还原区,上部为富氧区.燃烧器可100%的使用石油焦、煤、重油. 相似文献

某公司2 500t/d生产线窑尾采用五级预热器和KDS型分解炉,回转窑规格为Φ4m×60m。该线于2013年3月8日开始检修,检修后于3月21日投料。投料后窑系统频繁塌料,分解炉和预热器负压偏大,烟室负压和温度偏低,窑电流低,分解炉出口温度不稳定,出窑熟料黄心料较多,熟料质量差,窑产量提不上去。检修前后操作参数对比见表1。 相似文献

我公司是近期投产的2500t/d预分解窑生产线,回转窑规格为!4m×60m,分解炉采用TDF炉,预热器为五级双系列,燃烧器采用FLS生产的三通道燃烧器。2006年3月份,窑内出现飞砂料,影响了预分解窑的正常生产。经过分析,在操作管理上采取了几项措施,基本上消除了飞砂料,稳定了窑内的热工制度。 相似文献

0引言 小型五级旋风预热器窑的规模大多为 300t/d和 600t/d水泥熟料,规格多为Φ 2.5m× 42m、Φ 2.7m× 48m和Φ 3.2m× 52m。有人将它归为新型干法生产线,因而认为其熟料的配料方案和煅烧操作应与大型预分解窑一样。实际上,小型五级旋风预热器窑由于未设分解炉,生料入窑分解率低,加上大多采用单筒冷却机,二次风温度不高以及窑的直径小致使单位熟料的窑筒体表面散热损失大等原因,窑内熟料煅烧温度不高,因此其熟料的配料方案和煅烧必然不同于大型预分解窑。本文拟在分析五级旋风预热器窑的热工特性基础上,讨论其配料方案及熟料… 相似文献

A semi-empirical equation of state for metals is described. Its capabilities are demonstrated by the example of the equation
of state for aluminum. New experimental data are presented on the location of the isentrope of aluminum for unloading from
the state at p = 229.71 GPa on the shock adiabat to an aerogel (SiO2) of density 0.08 g/cm3.

A thermochemical rather simple experimental technique is applied to determine the enthalpy of formation of Diperoxide of ciclohexanone. The study is complemented with suitable theoretical calculations at the semiempirical and ab initio levels. A particular satisfactory agreement between both ways is found for the ab initio calculation at the 6–311G basis This set level. Some possible extensions of the present procedure are pointed out. 相似文献

A perturbation viscometer is a differential capillary viscometer that measures the logarithmic viscosity gradient of the viscosity-composition curve for gas mixtures. Measurements are made at different gas mixture compositions. Integration of the logarithmic viscosity gradients measured over the full composition range gives the mixture viscosity relative to the viscosity of one of the pure components of the gas mixture. This method is attractive because, for measurements of equal precision, integration of the gradients is potentially an order of magnitude more precise than measurement of the viscosities directly. It can also work at high and low temperatures and perhaps high pressures.The perturbation viscometer has been used to make measurements on ideal gas mixtures at ambient and elevated temperatures. The situation is more complicated when the gas mixtures are non-ideal. Extra effects due to density differences, molar volume change on mixing and differential thermal expansion may be measured in addition to the desired viscosity change producing systematic errors in the results. Thus, a more sophisticated apparatus is required. The standard perturbation viscometer has been modified to separate out the extra effects to permit measurement of the true change in viscosity. In addition, the theoretical operation of the modified apparatus has been revised to account for the design changes to permit calculation of the viscosity-composition profiles from the results.The apparatus has been tested using helium-HFC-125 mixtures and two new viscosity-composition profiles are presented for these mixtures at 23 and . Internal consistency tests have been used to confirm that the data produced are of high quality with an estimated uncertainty in the viscosity ratio data at of 0.9% and at of 1.5%. 相似文献
