电蒸汽锅炉流量不均匀的原因

电蒸汽锅炉原理是是把水加热到一定的热度产生高温的水蒸气,为供应提供高效的生产力量。电蒸汽锅炉的热偏差是主要是由于锅炉的吸热不匀和流量不匀造成的,下面主要给大家介绍一下电蒸汽锅炉流量不均匀的原因。

1、电蒸汽锅炉蒸发受热面并联各管的流动阻力不同和分配联箱沿长度的压力变化,以及各管子之间的重位压头的不同均可引起流量不均匀。

2、电蒸汽锅炉http://www.jnshengxin.cn/流动阻力对热偏差的影响。由于蒸汽管的结构、质量、长度、管径、粗糙度和弯曲度不同,其流动阻力也不一样,在压差相同的条件下,阻力的大小,将引起流量的不均匀。

Since the structure of the steam pipe, quality, length, diameter, roughness and different curvature, which is not the same resistance to flow, under the same pressure conditions, the size of the resistance, will cause uneven flow.

3、电蒸汽锅炉http://www.jnshengxin.cn/重位压头对热偏差的影响。在垂直上升管屏中,由于管屏高度相对较大,当并联各管受热不均匀时,密度就差得多,因而要考虑重位压头的影响。当个别管子热负荷偏高时,该管流量降低。但由于管中工质密度减小,重位压头降低,会促使流量增大。因此,重位压头有助于减小热偏差。
Effect on the thermal electric steam boilers deviation bit heavy pressure head. In the vertical riser pipe screen, the screen height is relatively large because of the tube, when the uneven heating tubes in parallel, the density is much more backward, and thus to consider the impact of re-position the indenter. When the high heat load individual tubes, the tube flow is reduced. However, due to the working fluid density decreases tubes, heavy head lowered position, will lead to increased traffic. Therefore, re-position the head helps reduce thermal deviation.
