摘要:

本工作研究了基于高密度复合相变储热材料电热锅炉的分时配比供热系统,对高密度复合相变储热材料及其电热锅炉进行了描述。结合冬季供热的负荷系数随室外环境温度的变化规律,对分时配比供热系统蓄热设备进行了优化设计,提出了分时配比供热系统的优化原则。结合城市供热的示范工程,分时配比供热系统与全蓄热式供热系统比较,不仅能够节省锅炉房空间31%,节约初投资33%,与传统直热式电锅炉比较节省运行费用46%,同时减少了锅炉房的用电负荷,降低了电力增容压力。通过供热负荷分析说明了分时配比供热系统具备极寒天气的供热调峰能力和设备备用功能。

Abstract:

This study explores a time-sharing heating system using an electric boiler, which is a high-density composite phase change material. By combining the variation law of the load coefficient of heating in winter with outdoor ambient temperature, the optimization design of the heat storage device of the time-sharing heating system was performed, and the optimization principle of the time-sharing heating system was proposed. Considering the demonstration project of urban heating as an example, the time-sharing and proportion heating system could save the boiler room's space by 31%, initial investment by 33%, and operating cost by 46%. Furthermore, the power load of the boiler room can be reduced and pressure of power capacity can be increased, compared with the traditional direct-heat electric boiler. The heating load analysis revealed that the time-sharing heating system could heat peak regulation and equipment reserve function in extremely cold weather.

Key words: composite phase change heat storage materials, time-sharing heating system, operating costs, heating support
