沸腾炉布风板设计,必须满足气体分布均匀,运行阻力小,小孔不漏料、不堵塞,风帽不过热烧坏,清渣方便,结构简单,日常维修工作量小等要求。jNe—Ay型布风板的设计,对上述要求作了充分的考虑。一、布风板阻力的确定布风板的通风阻力,是布风板设计的一个十分重要的参数。一定的布风板阻力是必要的。它可以使沸腾床配风更均匀一些,沸腾床层的沸腾工况和稳定性更好一些。从冷态试验台我们可以观察到,由于沸腾层过程料层间存在着气泡和料层剧烈波动,床层中
Boiler furnace wind board design, must meet the gas distribution, running resistance, small holes do not leak material, not blocked, the hood is not hot burn, slag easy, simple structure, small daily maintenance workload and other requirements. jNe-Ay-type design of the wind plate, the above requirements have been fully considered. First, determine the resistance of the wind board Wind board ventilation resistance, wind board design is a very important parameter. Certain windshield resistance is necessary. It can make the ebullated bed with a more uniform distribution of wind, ebullition boiling conditions and stability better. From the cold state test bench we can observe that because of the violent fluctuation of air bubbles and material layer between the material layers of the boiling layer,
