摘要
蓄热电锅炉又称储能式电锅炉,其供热是利用峰谷电价政策,将低谷电能以热能的形式储存在储能设备中,在电力峰期释放对外供热。本文根据国内外蓄热电锅炉供热技术的发展和应用现状,归纳总结了水蓄热、固体蓄热和相变材料蓄热电锅炉供热的特点,并对水蓄热电锅炉供热技术展开了研究,提出了针对其供热系统的容量设计计算方法,并编制了一款专门计算软件。某项目实际工程应用表明,采用该蓄热电锅炉供热技术年净收益约为1200万元,年消纳风(光)电量约为17964.06万kW·h,年供热量约为854245 GJ,节煤减排效果明显,市场潜力巨大,值得推广应用。
Thermal storage electric boiler is also known as energy storage type electric boiler,which works depending on the peak-valley electricity price policy.It stores the valley electricity in form of heat energy with energy storage equipment,and releases during peak periods for external heating.According to the development and application status of energy storage electric boiler heating technology in China and abroad,this paper summarizes the heating characteristics of thermoelectric boiler with water,solid and phase change material,and studies the technology of water storage thermoelectric boiler heating in depth.Moreover,a new computing method is presented for design capacity of the system,and a specialized calculation software is compiled.The actual engineering application of a project shows that,the annual net income of using the thermal electric boiler heating technology is about 12 million yuan,the annual absorption of wind(solar)electricity is about 179.6406 million kW·h,the annual heating load is about 854245 GJ,and the coal saving and emission reduction effect is obvious.In a word,the technology suggested has huge market potential,which is worth popularizing and applying.
