摘　　要：文章以养猪场为例,对合肥地区利用太阳能加热生产沼气进行了研究分析。合肥地区冬季寒冷,自然温度条件下沼气产量较低,沼气发酵原料存在很大浪费。采用太阳能加热方式,发酵温度在冬季可以维持在25℃,沼气产量比自然温度条件下可提高84%以上,存栏量相当于10头生猪的家庭养殖场生产的沼气可以基本满足3个家庭的日常用能需要。Taking a pig farm as the example, the paper studies and analyzes the solar energy assisted biogas production in Heifei area. The winter in Hefei area is chili, biogas output is lower under natural conditions, and there is large waste for the fermenting materials. By Adopting solar heating method, the fermenting temperature is able to be maintained over 25 ℃ in winter, and the biogas output may be increased by 84% above that under natural conditions. In this case, the biogas from a family hoggery of 10 live pigs could satisfy the daily energy requirements of three households.
