 Experimental and theoretical investigation of a flat heat pipe heat exchanger for waste heat recovery in the steel industryHussam Jouhara, Sulaiman Almahmoud, Amisha Chauhan, Bertrand Delpech, Giuseppe Bianchi, Savvas A. Tassou, Rocio Llera, Francisco Lago and Juan José Arribas Energy, 2017, vol. 141, issue C, 1928-1939 Abstract: Most of the energy demand in the steel industry is used for heating purposes. The recovery of residual heat contributes to significant reductions in both production costs and greenhouse gas emissions. In this paper, the design, manufacture and testing of an innovative heat recovery system based on a Flat Heat Pipe heat exchanger (FHP) is described. The FHP system consists of stainless steel heat pipes linked by a bottom header and a shell and tube top header. The thermal performance of the FHP was investigated both in the laboratory and on an industrial plant and the energy recovered and the working temperatures of the FHP are reported. A theoretical modelling tool has been built to predict the performance of the device in the laboratory. Reasonable agreement has been obtained between experimental and theoretical results. It is concluded from the results that the FHP is an innovative high efficiency technology for waste heat recovery from such industrial applications.
