First, the dynamic mathematical models for the typical components of the heat recovery steam generator are built up on the basis of fundamental physical laws, which are composed of the single-phase region models ( economizer 、 superheater and reheater) and evaporating zone model. 首先,从基本物理定律出发建立了余热锅炉典型部件动态数学模型,其中包括单相受热环节(省煤器、过热器和再热器)模型和蒸发区模型。
During a sustained stable-pressure steam purging the steam superheating of the separator has been controlled at about 20 ℃. Desuperheating water was used to control the superheater and reheater outlet temperature, thereby preventing the materials from being subjected to an excessively high temperature. 持续稳压冲管时分离器蒸汽过热度控制在20℃左右,利用减温水控制过热器和再热器出口温度,防止超过材料温限。
With steam parameter in boiler increased continuously, heating surface area of superheater and reheater became bigger and bigger, and the design and arrangement became more and more complex, and these lead to the flow and heat absorption capacity difference in parallel tubes unavoidably. 由于锅炉蒸汽参数的不断提高,过热器和再热器系统受热面积越来越大,设计和布置日趋复杂,不可避免地导致并联各管内的流量与吸热量发生差异。
Since the steam flow and pressure loss in headers of superheater and reheater tube banks is rather complicated, opinions differ on whether flow resistance of headers needs to be calculated. 由于电站锅炉过热器和再热器管组集箱中蒸汽的流动工况和压力损失机理比较复杂,所以对于是否需要计算集箱阻力这一项阻力一直有不同的看法。
