摘要

针对某新建供热锅炉房,分析一级管网循环泵(以下简称一级循环泵)初选方案中存在的扬程过大等配置不合理问题。结合锅炉配置(配置3台热功率相同的锅炉)及一级管网运行调节方式(分阶段变流量质调节),提出两种优化方案。优化方案1:分别配置小流量、中流量、大流量一级循环泵(均为定频泵),小流量泵满足1台锅炉运行流量要求,中流量泵满足2台锅炉运行流量要求,大流量泵满足3台锅炉运行流量要求。优化方案2:配置小流量、大流量一级循环泵(均为变频泵),小流量泵满足1台锅炉运行流量要求,大流量泵满足2台和3台锅炉运行流量要求。根据设备造价及设备配置是否有利于节能等因素,选取优化方案2。根据2016—2017年供暖期实测运行参数,将优化方案1作为对照组,对优化方案2进行后评价。与优化方案1相比,优化方案2的设备造价、供暖期电费均比较低,优化方案2的经济性最优。
        In view of a new heating boiler room project,the unreasonable configuration problem of the primary scheme of circulating pump in primary circuit( hereinafter referred to as primary circulating pump) is analyzed,such as too large head. Combined with the boiler configuration( 3 boilers with the same thermal power) and the operation regulation mode of the primary circuit( centralized control with flow varied by steps),two optimization schemes are proposed. Optimization scheme 1: small flow,medium flow and large flow first-stage circulating pumps( constant frequency pumps) are set up respectively,small flow pump meets operating flow requirement of 1 boiler,the medium flow pump meets operating flow requirements of 2 boilers,and large flow pump meets operating flow requirements of 3 boilers. Optimization scheme 2: small flow and large flow circulating pumps( variable frequency pump) are set up,small flow pump meets operating flow requirement of 1 boiler,and large flow pump meets operating flow requirements of 2 and 3 boilers. According to whether the equipment cost and equipment configuration are advantageous to the energy saving and other factors,the optimization scheme 2 is selected.According to the measured operating parameters during the heating period from 2016 to 2017,the optimization scheme 1 is taken as the control group and the optimization scheme 2 is evaluated after the optimization scheme 1. Compared with the optimization scheme 1,the equipment cost of the optimization scheme 2 and the electric charge during heating period are lower,and the economy of the optimization scheme 2 is the best.
