The invention discloses a flue gas desulfurization gypsum calcining furnace which comprises a calcining area, an air uniformizing plate, an air inlet pipe, a first air uniformizing area and a second air uniformizing area, the cross section of the calcining area and the cross section of the air uniformizing plate are both rectangular, the first air uniformizing area comprises a first air uniformizing cover arranged below the air uniformizing plate, and a first air uniformizing cone is arranged in the center of the first air uniformizing cover; the second air uniformizing area comprises a second air uniformizing cover arranged below the first air uniformizing cover, a second air uniformizing cone is arranged in the center of the second air uniformizing cover, and high-speed airflow sprayed out through the air inlet pipe enters the first air uniformizing area and the second air uniformizing area and then flows to the air uniformizing plate. Compared with an airflow with a rectangular section formed by using one air uniformizing area, the two air uniformizing areas can be used for adjusting the areas of the circular section and the four concave triangular sections, so that the flow of the airflow in the circular section and the four concave triangular sections is adjusted, the flow of the airflow in the circular section and the four concave triangular sections is basically the same, the airflow flows uniformly, and dead angles in the calcining area are reduced.
本发明公开了一种脱硫石膏的煅烧炉，包括煅烧区、均风板、进风管、第一均风区和第二均风区，煅烧区和均风板的横截面均是矩形的，第一均风区包括设置在均风板下方的第一均风罩，第一均风罩的中心设置有第一均风锥，第二均风区包括设置在第一均风罩下方的第二均风罩，第二均风罩的中心设置有第二均风锥，通过进风管喷出的高速气流分别进入第一均风区和第二均风区，然后流向均风板。与使用一个均风区形成矩形截面的气流相比，使用两个均风区能够调节圆形截面和四个内凹三角形截面的面积，进而调整两者中的气流的流量，使得两者的气流流量基本相同，从而使得气流均匀流动，减少煅烧区中的死角。
