摘要
对3种余热利用途径(工艺方式、能量方式和综合方式)进行了研究,导出了节能量的计算公式。对常见的余热回收方法——利用换热器预热空气进行了详细的分析,讨论了换热器型式及大小对炉子燃料利用率和节能率的影响,提出了换热器优化设计和选择的方法。
Three methods of waste heat recovery, including technological, energetical and comprehensive method, are studied. The formulae of energy savings of these methods are derived. The practical waste heat recovery method, preheating combustion air by the heat exchanger is also analysed and the effects of type and size of the heat exchanger on fuel utilization coefficient and energy savings of furnace are discussed. The optimum method of designing and selecting heat exchanger is proposed.
