摘　　要：针对现有固体蓄热电锅炉换热效率较低、锅炉房占地面积大的不足,主要对新型固体蓄热电锅炉的对流管束部分进行优化,将对流管束蓄热体进行系统分析。考虑资金的时间价值,从技术经济动态角度进行分析,将系统的费用通过费用现值法折现至初期,以系统寿命期内的成本折现值最小为目标,以对流管束物理结构与热量守恒为约束构建数学模型,对该模型提出求解方法以及算法的程序说明。最终通过优化固体蓄热电锅炉的对流管束直径、管间距和长度这三个自变量,在满足采暖热负荷的情况下,使寿命周期内的成本折现值达到最小。In response to the shortcomings of low heat transfer efficiency and large footprint of the boiler room in existing solid heat storage electric boilers,this article mainly optimizes the convection tube bundle part of the new solid heat storage electric boiler,and systematically analyzes the convection tube bundle heat storage body.Considering the time value of funds and analyzing from the perspective of technological and economic dynamics,the system costs are discounted to the initial stage through the cost present value method.The goal is to minimize the discounted cost value within the system's lifespan,and a mathematical model is constructed with the physical structure of the convection tube bundle and heat conservation as constraints.A solution method and program explanation of the algorithm are proposed for this model.Finally,by optimizing the three independent variables of convection tube bundle diameter,tube spacing,and length of the solid thermal storage electric boiler,the cost discount value during the service life is minimized while meeting the heating load.
