随着对发电设备的效率和运行可靠性的要求不断提高,就要求所有部件具有先进技术。从而对容克式空气预热器(包括风、烟道)的结构和设计的要求更为严格。影响空气预热器受热面效率的因素之一是预热器入口截面的气流动力工况,而且空气侧和烟气侧都是一样的。进入空气预热器受热面的烟气入口处气流不均匀时,传热量就减少,也就影响到空气的加热程度。同样,沿通道截面空气不均匀
As the requirements for the efficiency and operational reliability of power generation equipment continue to increase, all components are required to have advanced technology. As a result, the requirements for the structure and design of Junker air preheaters (including wind and flue) are stricter. One of the factors that affect the efficiency of the heating surface of an air preheater is the aerodynamic condition of the inlet section of the preheater, and the air side and the flue gas side are the same. Into the air preheater heating surface of the flue gas inlet uneven, heat transfer will be reduced, it will affect the degree of air heating. Likewise, the air along the passage cross-section is not uniform
