蒸汽节能设备和适用范围是如何监测的？监测合格主要表现在哪几方面？

日期： 2025-08-20 作者：

蒸汽加热设备能源利用的监测内容、方法和合格指标主要依据国家标准 GB/T 15914-2021，适用于用汽功率≥325kW或用汽负荷≥0.5t/h的蒸煮、蒸发与蒸馏、干燥及综合用汽设备。

蒸汽加热设备包括四类：

一、烹饪设备；

二、蒸发蒸馏设备；

三、蒸汽加热干燥设备；

四、综合汽车设备。

根据我国目前的实际情况，蒸汽加热设备的蒸汽功率设置为≥325kW（蒸汽量≥0.5t/h）。如果蒸汽量小于此，则不会进行热效率监测。但在特殊情况下，如果某企业的蒸汽加热设备较多，但每台蒸汽量小于0.5t/h，但总蒸汽量大于10t/h，则仍可监测和测试项目，并评估其蒸汽加热设备的能源利用水平。

现场测试：包括疏水温度、排气温度、溢流水温度等关键参数的实时测量。

本标准不适用于蒸汽动力设备。

由于本标准不包括蒸汽动力设备的效率测试和计算方法，如汽轮机（发电）、蒸汽机车（运输）、蒸汽锤等节能监测方法，因此需要单独制定监测标准。

监测合格指标主要体现在以下三个方面：

一、热效率：不同设备类型（如蒸煮、蒸发、干燥）的热效率需达到标准规定的最低值（如蒸煮设备≥85%，蒸发设备≥80%）。

二、保温性能：蒸汽管路保温层需保持完好，避免热量过度散失。

三、凝结水回收：回收率需≥90%。

蒸汽余热回收主要有以下两种方案：

一、工业蒸汽系统在蒸汽换热后存在高温冷凝水、低品质蒸汽、乏汽等余热未回收的问题蒸汽排气阀冷凝水系统热泵引射器余热回收冷凝水回收装置闪蒸罐蒸汽减温减压晟德亿蒸汽发生器蒸汽调节阀高温冷凝水回收水浴式减温减压装置及厂家水浴式减温减压器通过热泵引射提温增压系统将蒸汽转化为满足用汽设备工艺参数的高品质蒸汽冷凝水回收闪蒸罐装置彻底解决了锅炉连排损失问题。
