| 1 | 煤粉燃烧中NO_x和SO_x生成的详细反应机理模拟显示文摘采用详细化学反应机理与CFD方法耦合的煤粉燃烧数值模拟程序,计算了煤粉燃烧过程中CO,NO_x和SO_x等的浓度分布特性.通过与实验对照,验证了数值模拟方法的可靠性,并分析了燃烧温度和煤粉细度等因素对于NO生成的影响.结果表明温度对于NO的生成影响较大,随着温度的增加,NO的生成浓度明显增加;对于不同煤种,可能存在一个温度点,这时NO的生成速率将非常快;在计算范围内,温度对SO_2的最终生成浓度没有明显影响,而只影响SO_2的释放过程.煤粉细度对于NO生成有较小的影响. | 魏小林 韩小海 Uwe Schnell Günter Scheffknecht Benedetto Risio | 2008 | 力学学报2008，40，6： | 8 |

| 18 | Sulphite measurement and its influence on Hg behaviour in wet-limestone flue-gas desulphurization显示文摘The most abundant and typical reducing agent for oxidized mercury in the slurry of wet flue-gas desulphurization(FGD)is the absorbed sulphur dioxide(SO_(2)),which is present as different species of bisulphite or sulphite,depending on the pH of the slurry.In this study,two different measurement principles for continuous sulphite measurement in the slurry of lab-scale FGD were investigated to check their feasibility to be implemented in a wet FGD.The first method is based on light absorbance at the characteristic wavelength of sulphite measurement using a spectrophotometer and,in the second method,sulphite is measured as sulphur dioxide using a gas sensor.In addition,the correlation of sulphite concentration and mercury(Hg)in the slurry can be shown by measuring sulphite semi-continuously.It was concluded that using a spectrophotometer leads to distorted results.In contrast,measuring sulphite as SO2 in the gas phase proved to be more selective.The implementation of the measurement technique in the lab-scale FGD showed promising results for sulphite measurement.Thus,the correlation of Hg and sulphite concentration could be shown at different synthetic slurries containing different halides.Using a slurry without halides demonstrated the ambivalent influence of sulphite in reactions involving Hg,in which sulphite acts as a ligand for Hg complexes as well as a reducing agent,depending on the existing concentration.However,in the presence of halides,the role of sulphite was less significant. | Ida Masoomi Sophia Bruttel Marc Oliver Schmid Günter Scheffknecht | 2020 | Clean Energy2020，4，4： | 0 |
| 19 | Experimental study of the effect of friction phenomena on actual and calculated inventory in a small-scale CFB riser显示文摘Accurate information concerning riser inventory in a fluidized bed is required in some applications such as the calcium looping process,because it is related to the CO_2 capture efficiency of the system.In a circulating fluidized bed(CFB),the riser inventory is normally calculated from the riser pressure drop;however,the friction and the acceleration phenomena may have a significant influence on the total riser pressure drop.Therefore,deviation may occur in the calculation from the actual mass.For this reason the magnitude of the friction and the acceleration pressure drop in the entire riser is studied in small-scale risers.Two series of studies were performed:the first one in a scaled cold model riser of the 10 kW_(th)facility,and the second one in the 10kW_(th) fluidized bed riser under process conditions.The velocities were chosen to comply with the fluidization regimes suitable for the calcium looping process,namely,the turbulent and the fast.In cold-model experiments in a low-velocity turbulent fluidization regime,the actual weight(static pressure drop) of the particles is observed more than the weight calculated from a recorded pressure drop.This phenomenon is also repeated in pilot plant conditions.In the cold-model setup,the friction and acceleration pressure drop became apparent in the fast fluidization regime,and increased as the gas velocity rose.Within calcium looping conditions in the pilot plant operation,the static pressure drop was observed more than the recorded pressure drop.Therefore,as a conservative approach,the influence of friction pressure drop may be neglected while calculating the solid inventory of the riser.The concept of transit inventory is introduced as a fraction of total inventory,which lies in freefall zones of the CFB system.This fraction increases as gas velocity rises. | Ajay R.Bidwe Glykeria Duelli(Varela) Heiko Dieter Gnter Scheffknecht | 2015 | Particuology2015，13，4： | 0 |
