【摘要】 通过试验研究了四角布置切向燃烧锅炉炉膛内的热负荷分布情况，比较了投入与不投入夹心风时炉内热负荷分布的变化。试验在一小型热态模拟试验台上进行，使用了一种自制的辐射式热流计。试验所用燃料为铜川贫煤。结果表明，投入夹心风后炉内热负荷沿炉膛高度方向的衰减速度加快。更多还原

【Abstract】 An experimental study has been conducted of the thermal load distribution in a tangentially fired boiler furnace with burners installed at the four corners of the boiler.The variation of the thermal load distribution is compered for cases with or without the use of tertiary air. With the help of a self-made radiation type heat-flux meter the test has been performed on a small-size hot-state simulation test rig with lean coal of Tongchuan serving as the test fuel.The tset resuits have shown that the injection of tertiary air can lead to a quickening of the damping tempo of the infurnace thermal load along the furnace height.更多还原
