对前拱高度与炉排长度之比为0.333、后拱高度与炉排长度之比为0.12和前拱倾角为45°的层燃垃圾焚烧炉进行了8种工况的冷态试验分析,实验得出:较合适的前后拱动量流率比在1∶2.1~1∶5.4范围内;在垃圾层表面以上空间,湍动度沿炉排长度方向分布的总趋势呈炉前、炉后的湍动度值小,在3.5%~6%范围内变化。
Eight kinds of working conditions of the cold-burning test were carried out on the layer burning waste incinerator with the ratio of the height of the front arch to the length of the grate of 0.333, the ratio of the height of the rear arch to the length of the grate of 0.12 and the inclination of the front arch of 45 °. The results show that the suitable flow rate ratio of anterior and posterior arch is within the range of 1: 2.1 to 1: 5.4. The general trend of the turbulence along the length of the grate is above the surface of the refuse layer, Dynamic value is small, in the range of 3.5% to 6% change.
