燃气锅炉房供热系统运行调节实际效果

Actual Effect of Operation Regulation of Heating System with Gas Boiler Room

某燃气锅炉房供热系统采取分阶段改变流量的质调节方法。对供暖期运行调节的实际效果及耗气量、供热参数进行分析。在基本满足室内温度要求的前提下，严寒期一级管网供、回水温度变化范围分别为46～67℃、40～55℃，低于设计供、回水温度95、70℃，系统能耗在合理范围内。

In a district heating system with gas boiler room, the flow rate is changed at different stages and the water temperature is adjusted. The actual effect of operation regulation, gas consumption and heating parameters during the heating period are analyzed. Under the premise of basically meeting the indoor temperature demand, the supply and return water temperatures of the primary circuit vary from 46℃ to 67℃ and from 40℃ to 55℃ respectively during the severe cold period, rather than being fixed at the design supply and return water temperatures of 95℃ and 70℃. The energy consumption of the system is within a reasonable range.
