A Japanese heavy industrial company was responsible for general design of the FGD project of 2 x 600 MW for Hebei Guohua Dingzhou Power Plant, phase I and Hebei Provincial Electric Power Survey Design Research Institute undertook the design of detailed drawings as a subcontractor. The design features of FGD duct are as follows: large stiffness of flue gas duct, application of reinforced ribs and internally supported bridge structure, installation of leading plate, prevention of internal overarm support resonance ; consideration of hanger and support with thermal expansion, special requirement done for welding duct, erection of manhole and drainage of duct.

河北国华定洲发电厂2×600 MW一期工程烟气脱硫工程,总体设计由日本川崎重工业株式会社负责,河北省电力勘测设计研究院作为分包商承担烟道的详图设计。该烟气脱硫工程烟道的设计特点是:烟道的刚性较大;采用了加固肋及内撑桁架;设置了导流板;防止了内撑杆共振;考虑了支吊架及热膨胀的问题;烟道的焊接作了特殊要求;设置了人孔门和烟道疏水等。

The problems and uneconomic steel consumption as well as large space occupation existing presently in the FGD flue design show the neccssity of design optimization.The optimization analyses of the flue thickness,type and dimension of reinforcement ,and distance between reinforcements etc.are condueted.The concusions are obtained from the curves of optimization calculation results :rigidness and distance between reinforcemeuts increase as increasing flue thickness.If H profile steel is adopted as flue reinforcement,the...

对目前脱硫烟道设计中存在的问题和耗钢材及空间大的不经济性提出了优化的必要性。对烟道壁厚及其加固肋采用的型钢种类、尺寸、肋间距等进行了优化分析。由优化计算结果曲线得出了结论:烟道壁厚增加可使其刚度和加固肋间距增加,若采用H型钢加固肋,效果更为明显,可节省大量钢材造价和布置空间。另外,对于需防腐的净烟道,若采用有防腐措施的内撑杆,可大幅降低加固肋的高度和钢材消耗。

At present,the method to design the pipeline in power plants in China and abroad are different.In China,the version of the ex-Soviet Union was used for many years.But it proved not very rational in practice.After many designing methods have been proposed many times,the method now widely used in China is offered.It is a method like this: the pressure is mostly born by the cross stiffening ribs,and a part of the pressure is taken on by the inside fit bear.The plate of the pipes is computed as a thin plank with...

At present,the method to design the pipeline in power plants in China and abroad are different.In China,the version of the ex-Soviet Union was used for many years.But it proved not very rational in practice.After many designing methods have been proposed many times,the method now widely used in China is offered.It is a method like this: the pressure is mostly born by the cross stiffening ribs,and a part of the pressure is taken on by the inside fit bear.The plate of the pipes is computed as a thin plank with large plastic deflection.In this article,the rationality of this method was checked using the software ANSYS.The finite element method were used to check the rationality of the method mentioned above.

国内外火力发电厂烟风煤粉管道加固肋设计计算方案不尽相同。我国沿袭了前苏联的设计计算方案,经实践证明并不十分合理后,经改良设计,提出了横肋为主,适当考虑内撑杆承受内外荷载,按照薄板大挠度塑性变形计算模式进行板的控制计算。文章通过ANSYS建模模拟烟风煤粉管道的实际情况,用有限元方法校核这种加固肋设计的合理性。
