供热二级网侧设置燃气调峰锅炉的探讨及节能分析

Discussion and energy efficiency analysis of installing peak-shaving gas boilers in secondary heat supply network side

提出了在供热二级网侧设置燃气调峰锅炉的二级调峰供热节能方案,针对国内集中供热现状分析了该方案的运行特点与优势。采用温频法计算了某供热工程的年耗热量,对该工程就二级调峰方案和现有供热方案进行比较,分析了两种方案在能耗、初投资及年运行费用方面的差异,结果表明二级调峰方案具有良好的节能效果和经济优势。

Proposes an energy efficiency scheme of heat supply in which gas boilers are installed in the secondary heat supply network side as peak-shaving boilers. According to the present situation of central heating in China, analyses the characteristics and merits of the scheme. Calculates annual heat consumption of a real project by BIN method. Compares the scheme with the Present heating scheme in energy consumption, initial investment and annual operation expenses. It is shown that the new scheme is feasible in energy efficiency and is more economic,
