长输供热系统大温差机组实际效能评价

吸收式大温差机组是长输供热系统中降低一次网回水温度的关键,其实际效能对长输供热项目的节能、环保以及经济性起着决定作用。大温差机组的性能受诸多因素的影响,本文将针对一次网、二次网供回水温度及水质对机组性能的影响,选取太古长输供热系统中部分大温差机组,对其实际效能进行评价,以便更好地指导实际生产运行工作。

The absorption large temperature difference unit is the key to reduce the return water temperature of primary network in the long-distance heat supply system.Its actual efficiency plays a decisive role in the energy saving,environmental protection and economy of the long-distance heat supply project.The performance of large temperature difference units is affected by many factors.In this paper,some large temperature difference units in the taigu long distance heating system are selected to evaluate their actual performance according to the influence of the primary and secondary network water supply temperature and water quality on unit performance,so as to better guide the actual production and operation.
