沼气工程太阳能双效增温系统热平衡分析

Heat Equilibrium Calculation of Solar Two Calefacient Effects on Biogas Digester

根据我国北方冬季气温偏低、沼气池产气慢且少的特点,结合日照特点,设计了由太阳能温室和集热室两部分组成的太阳能双效增温沼气系统。利用传热学的基本理论,建立了沼气系统的热平衡方程,并通过理论计算,分析了太阳能双效增温沼气系统内各部分的热利用效率。

According to low temperature in winter in northern China, and the biogas digester generate slowly and less biogas, combined with abundant sunlight, we design a solar two calefacient effects on biogas. Build the Heat equilibrium equation based on the diathermanous theories. Through theoretical calculations, analyze the thermal effect of every part in this system.
