摘要： 现今的人们则对能源的利用已经到了离不开的地步。而随着不可再生能源的日益接近枯竭，人们也在不断寻找新的能源。而其中太阳能则是十分能满足我们需要的。从太阳光中，我们可以获得无限能源。几乎所有人都知道，用放大镜加热物体时的热量其实是十分客观的，而制作一面巨大的类似放大镜的镜面来加热物体，即是这篇论文的主题。本设计根据太阳能聚焦发热原理，结合所学的相关知识、查阅相关设计资料，针对有关的设计要求设计一套聚焦型太阳能加热装置。生物质低温预热解并不需要十分高的温度，通过太阳能转化的热能完全可以用于生物质低温热解预处理，用聚焦型太阳能加热装置来对其进行加热并且非常经济、合适。本文根据东南沿海地区（以上海为例）光照为基础，提出了聚焦型太阳能加热装置方案，设计功率为 10KW，在设计过程中指出了其可行性和实用性，解决可再生能源开发利用中的应用技术问题。 35870

Focus solar heating solid pretreatment plant design Abstract: Nowadays people to the sources of energy use has to leave With the increasingly close to depletion of non-renewable energy, people are constantly looking for new sources of energy The solar energy is very can meet our need In the light of the sun, we can obtain the infinite energy Almost everyone knows, a magnifying glass heating objects when heat is actually very objective, and making a huge similar magnifying mirror heating the object, that is the subject of this article. According to the design of solar energy focusing and heating principle, combining the knowledge, access to relevant design data, according to the design requirements and design a set of focusing type solar energy heating device The biomass under low temperature preheating solution does not require very high temperatures, through the conversion of solar energy heat energy can be used for biomass pyrolysis pretreatment, with focusing type solar energy heating device to be heated and very economical, suitable. In this paper, according to the southeast coastal region (for example of Shanghai) light is a foundation, put forward focusing type solar energy heating device, design power of 10KW, in the design process and points out the feasibility and practicability of the solution, the exploitation and utilization of renewable energy application technology.
Keywords: Focusing type solar energy heating equipment(PTC);solar power; Biomass heating
