我国目前的酸雨区已超过国土面积的三分之一，2005年的S排放量达到2549万t，超过总量控制指标749万t，加剧了我国的大气污染火电厂是S的主要排放源，我国2004年1月1日实施的GBl3223-2003《火电厂大气污染排放标准》按时段规定了火电厂的大气污染物最高允许排放值，加快了我国火电厂脱硫装置的投入使用，对于单机容量超过20MW的大型燃煤火电机组，国内外目前流行的脱硫工艺是采用湿法脱硫，在完成脱硫要求的同时，可以同时产生副产品石膏，实现脱硫副产品的资源再利用，我国现在运行的许多火电厂在原设计中没有考虑脱硫装置的安装位置，这使运行的火电厂增加脱硫装置带来了困难，未来10年装机容量3×10MW的火电机组均需要安装脱硫'>烟气脱硫装置，因此，我国现在运行的火电厂急需一种既具有高脱硫效率且节省占地面积的湿法脱硫新工艺，母公司为德国鲁尔集团公司(Ruhr AG)的德国斯特雅克集团公司(steag AG)自1969年开始研发以CaO或CaCO为脱硫剂的紧凑式湿法脱硫新工艺，该工艺具有脱硫效率高、占地面积小的独特优点，1977年在德国wilhelmshaven第一套具有商业化使用价值的紧凑式湿法脱硫工业化试验设备对5×10Nm/h的燃煤电厂烟气进行脱硫，相应的汽轮发电机组的电功率为140 MW；1982年第一台工艺脱硫设备在该电厂投入运行，脱硫的烟气量为1.5×10Nm/h，相应的汽轮发电机组的电功率为450 MW，该工艺到2000年已成功应用的火电机组容量超过2×10MW，单台锅炉的最大额定烟气流量为2.29×10Nm/h，单台汽轮发电机组的最大额定电功率为750MW，紧凑式湿法脱硫工艺特别适用于已运行电厂增加脱硫装置的改造方案，对我国大批火电厂的增加脱硫装置的改造方案具有重要的实用价值 ......
Experimental study on the width of the turbulent area Around bridge pier
Abstract
At present，the method of calculating of the turbulent flow width around the bridge pier is not given in the "Standard for Inland River Navigation"(GB50139—2004)in China,and the bridge designer usually increases the bridge span in order to ensure the navigation safety,which increases both of the structural design difficulty and the project investments．Therefore．It is extremely essential to give a research on the turbulent flow width around the bridge pier．Through the experiments of the fixed bed and the mobile bed，the factors influencing the turbulent flow width around the bridge pier have been analyzed，such as the approaching flow speed，the water depth，the angles between the bridge pier and the flow direction，the sizes of bridge pier,the shapes of the bridge pier,and the scouring around the bridge pier,etc.Through applying the dimension analytic method to the measured data,the formula of calculating the turbulent flow width around the bridge pier is then inferred．
Keywords：bridge pier；mobile bed experiment；fixed bed；width of turbulence area
1Introduction
The fluid state nearby the bridge pier normally changes shortly after the new birdge is built.Meanwhile,there exists unsafe navigation region(turbulent flow width) around the bridge pier.Thus,the accidents that the ships collide with bridge piers occurred frequently.Chen Mingdong,wang Duoyin have researched that the route width B plus the margin width equals Navigational clearance width of the bridge in the Mountainous areas rivers，the Three Gorges district and the Yangtze downriver areas．Hu Xuyue from Changsha University of Technology has researched the turbulent flow width around the bridge pier to a Certain extent．The research has been obtained that the turbulent flow width around bridge pier equals 3D(D：the diameter of the pier)within the experimental Fr scope．
At present，in the computation of the navigational clearance width of the bridge，the formula ......
