国家颁发的“供热系统节能工作暂行规定”,对企业的疏水阀应用管理以及凝结水的回收节能提出了具体的标准和要求。供热系统中疏水阀的选用和布置,以及凝结水回收系统的论证和设计,必须确定用热设备的蒸汽需要量,掌握凝结水排放的特点和数据。本文根据国外有关资料经编译整理而成,介绍用热设备蒸汽需要量的确定方法,以及一些常见用热设备的蒸汽耗量(或凝结水量)的估算,其中还提及各种应用场合下疏水阀排水量的确定。
The “Provisional Regulations on Energy Saving for Heating Systems” issued by the government puts forward specific standards and requirements for the application and management of steam traps and the recovery and energy saving of condensed water. The selection and arrangement of traps in the heating system and the demonstration and design of the condensate recovery system must determine the steam requirements of the heating equipment and master the characteristics and data of the condensate discharge. This article has been compiled according to relevant foreign data, describes the method for determining the steam requirements for thermal equipment, and the estimation of steam consumption (or condensed water) for some common thermal equipment. It also mentions the hydrophobicity of various applications. The determination of valve displacement.
