分布式小型燃气锅炉调峰研究

Research on peak load regulation of distributed gas fired boiler

随着供热技术和运行水平的不断提高,在热力站内二次网侧增设调峰锅炉成为研究者们重点关注的问题。本文主要以太原市的供热现状为基础对热力站内分布式燃气调峰锅炉与供热系统串联进行研究,通过理论分析给出了一次网分阶段质调节和等供水温度的量调节、一次网等供回水温差的量调节两种调节方式。在此基础上,深入研究两种调节方式下供热系统在调峰前后运行参数的计算方法,本文的研究结果将对分布式调峰锅炉的优化运行提供有利指导。

With the continuous improvement of heating technology and operation level, adding peak shaving boiler in the secondary network side of the heating station has become the focus of researchers. Based on the current situation of heating in Taiyuan City, this paper analyzes the series connection of distributed gas peak shaving boiler and heating system in the heating station. Through theoretical analysis, two kinds of regulation modes are given, i.e.,the staged quality regulation of primary network, the quantity regulation of equal water supply temperature, and the quantity regulation of equal water supply and return temperature of primary network. On this basis, the calculation methods of operation parameters of heating system before and after peak shaving under two kinds of regulation modes are deeply studied. The research results of this paper can provide beneficial guidance for the optimal operation of distributed peak shaving boilers.
