生物质能-太阳能互补供热系统优化设计

为了提高生物质能-太阳能互补供热系统的经济效益,该文从经济性角度对系统的主要参数进行优化设计,提出了一种生物质能-太阳能互补供热系统设计方案,建立了系统的经济分析模型,并采用线性规划的方法进行优化,并以北京地区一供热面积为200m2的办公楼为例进行了优化。结果表明,建立的经济分析模型可用,其中,太阳能集热器的价格、生物质颗粒燃料的价格、蓄热水箱的价格、生物质颗粒燃烧器的价格对系统中各部分参数的优化结果有影响,且影响程度依次降低。这可为今后生物质能-太阳能互补供热系统的设计提供参考。

Optimal design of biomass-solar complementary heating system

In order to improve the economic benefits of the biomass-solar complementary heating system, optimization design on the economical efficiency is necessary. In this paper, a design scheme of biomass-solar complementary heating system was put forward. The economic analysis model on this system was set up. A linear programming method was used to optimize the scheme .The system was optimized taking a 200m2 building in Beijing for example. The results showed that the established economic analysis model was available, in which the price of the solar collectors, biomass pellet fuel, heat storage tank and the biomass pellet burner effected on the optimization results of the various parts parameters in the system, and the degree of influence decreased systematically. It can provide areference for the design of biomass - solar complementary heating system in the future.
