This paper presents the cold-state aerodynamic field simulation test results for a WG 300 MW boiler furnace. The test results have shown that the different dynamic pressure ratio of the primary air and secondary air, the feeding mode fo the primary air and the layout format of the burners will all exercse a certain influence on the in-furnace aerodynamic field. The said results can be employed to guide the furnace design and operation of the home-made 300 MW boiler units and other tangenti... 文中给出了对ＷＧ３００ＭＷ机组锅炉炉膛进行冷态空气动力场模化试验的结果。试验结果表明，不同的二次风与一次风动压比、一次风的投运方式。燃烧器的布置方式等均会影响到炉内的空气动力场。这些结果对我国３００ＭＷ机组锅炉及其它切向燃烧锅炉炉膛的设计和运行均有重要的指导意义。 文摘来源 The diameter of actual tangential circle in furnace has major effect on the coking and the gas deviation in gas ducts.This paper discusses several schemes of tangential circle layouts, which are advantageous to reduce the coking in furnace and the deviation of gas in ducts, as well as existing problems in actual operation; and introduces the adjusting method for supposed tasngential circle. In the actual operation of boilers, adjusting the rocking angles and the dynamic pressure ratio of p... 炉内实际切圆的大小对炉膛结渣和水平烟道的烟气偏差有重要的影响，本文讨论了几种利于减缓炉膛结渣和水平烟道烟气偏差的切圆布置方式，以及在实际运行中存在的问题，介绍了假想切圆的调整方法。在锅炉的实际运行中，调整燃烧器摆角和一、二次风的动压比，间隔投用燃烧喷口，避开上大下小的配风方式等对减缓结渣和烟气偏差有一定的好处。 文摘来源 A row of jets discharging normally into a confined cylindrical crossflow was numerically investigated using the control volume based finite difference method. The relationship between the temperature trajectory and the upstream flow and geometric variables was determined.Parameter variations studied include nozzle diameter, nozzle number, duct radius, jet and mainstream volume flow, temperature ratio and dynamic pressure ratio.
