摘要
以某厂四角燃煤锅炉为例，进行一、二次风同心正反切时炉内冷、热态试验研究，并进行数值模拟与之对照。试验和数值模拟结果均表明：当一、二次风气流以一定角度交叉送入炉膛时，合理调节一、二次风气流配风角度，采用合适的一、二次风动量矩的比值，能够改善炉内空气动力结构，减少煤粉气流刷墙贴壁。
his report has one pulverized coal boiler in a plant as an example, and carries on cold and hot state experimental research while opposing tangential circle direction of primary air flow and secondary air flow, comparing with numerical simulation. The results of the experiments and the simulation show that when primary air flow and secondary air flow enter a boiler with same degree, adjusting reasonably the direction of primary and secondary air flow and adopting a appropriate number of air flow momentum torgue devided by primary air flow momentum torgue, we can get a better flow field in a boiler, and modulate pulverized coal air flow close to water walls, and prevent from slagging in a boiler.
