Abstract

Abstract

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.
