摘要
通过对新Ⅱ型生物质成型燃料热水锅炉进行正、反平衡计算和分析,得出新Ⅱ型生物质成型燃料热水锅炉的主要损失部位和参数,用反平衡效率分析得知燃烧不可逆损失最大,约为69.93%,其次为传热不可逆损失,约为14.50%,并用可避免损失概念对计算结果进行分析,表明采用可避免损失概念后,燃烧部位、传热部位、排烟部位的实用效率分别为42.6%、86.2%、92.1%。
Exergy analysis is a kind of scientific and comprehensive energy analysis method.By making positive and negative thermal balance analysis on new type Ⅱ biomass briquette hot-water boiler,we got the conclusion that the largest exergy loss lies on irreversible burning which reaches 69.93%,and irreversible heat transfer exergy losses follows,reaches 14.5%,then the calculation results were analyzed using the concept of avoidable exergy loss,the results show that the position of combustion,the position of heat transfer,the position of smoke and the practical efficiency of the exergy are respectively 42.6%,86.2%,and 92.1% after adopting the concept of avoidable exergy loss.
