【摘要】 在北方高寒地区,农村多数农户一直延续生物质直燃的单一模式采暖,不仅浪费了可再生能源还造成环境污染等问题,本文以节能减排、减少环境污染和提高农村的生活水平为宗旨,参照大中型锅炉的设计方法,提出了一套适用于小型户用沼气锅炉热力计算的方法。通过理论计算和选取相应的参数,利用炉膛出口温度和排烟温度先假设与后校核的方法,对沼气锅炉辐射换热面和对流换热面进行理论设计计算,并设计出沼气锅炉的整体结构。本设计计算误差为0.22%远小于2%,本设计符合锅炉的设计要求。更多还原

【Abstract】 In the north,rural alpine region continues the single mode of straight burning biomass to heat,not only wasting renewable energy also causing environmental pollution.This paper aims at energy conservation and emission reduction,and reduces environmental pollution and improves the rural life level.Basing on the design method of large and medium-sized boiler,this paper puts forward a set of suitable thermodynamic calculation method for small domestic biogas boiler.Through theoretical calculation and select the corresponding parameters,it first assumes the chamber exports and smoke exhaust temperature,and later checks.It affords the overall structure of the methane boiler after theory calculation of the radiation heat transfer surface and convective heat transfer surface.This design calculation error is 0.22%less than 2%showing this design conforming to the boiler design requirements.更多还原
