锅炉热效率的高低与其运行、维护、管理各环节有着直接关系.为了提高效率,降低能耗,我们采取了如下措施.1.有效控制空气过剩系数锅炉运行中,为追求较低的排渣含碳量,往往采取加大风量的办法,致使空气过剩系数太人,严重影响厂燃料与空气的混合,也使炉膛温度降低.不利着火,降低厂锅炉热效率.其原因在于操作无统 标准可依.WGC-450/39~(20)型中压中温层燃炉的正确操作,在于炉床上的不同燃烧过程需要供给不同的空气量,即加热干燥区段和灰渣段无需配给空气;干馏段和残余固定碳燃烧段仅需少量空气;需要大量配给空气的是主燃烧区段.因为现有锅炉未配备空气过量系数表计,运行人员仅能凭经验观察火焰或烟气颜色判断空气量的多少,从而影响了锅炉经济运行.
Boiler thermal efficiency level and its operation, maintenance, management has a direct relationship between the various sectors.In order to improve efficiency and reduce energy consumption, we have taken the following measures: 1. Effective control of air excess coefficient Boiler operation, in order to pursue lower slag carbon content Volume, often to increase the amount of wind approach, resulting in too much air excess coefficient, a serious impact on plant fuel and air mixture, but also to reduce the furnace temperature. Adverse unfavorable fire, reducing boiler thermal efficiency. The reason is that there is no standard operating procedures. The correct operation of WGC-450/39 ~ (20) medium pressure medium temperature stope combustion furnace is that different combustion processes on the hearth need to supply different amount of air, that is, heating and drying section and ash section need not be equipped with air; Only a small amount of air is required for the remaining fixed carbon combustion section, and the main combustion section, which requires a large amount of air distribution, is not available in the existing boilers, so operators can only judge the amount of air by empirical observation of flame or flue gas color , Thus affecting the economic operation of the boiler.
