Résumé

The European market study carried out by IFP and CREUSOT-LOIRE in the present framework has shown that a 2 millions toe/year savings can be expected from new gas - gas heat recovery systems in the present industrial context. The main constraint to be overcome is the cost of setting up in industrial plants. The compactness and modular conception of the new stacked perforated plates (SPP) gas- gas heat exchanger will undoubtedly help in getting this new equipment on to the market. The exchanger consists of a block formed by the stacking of judiciously superpositioned perforated metal plates whose apertures create the fluid flow passages. This compact gas - gas cross flow heat exchanger is easy to manufacture, with low pressure drops and easy to clean fume passages. The different plates perforations geometries, tested in laboratories on small models (exchange area : 0.35 m**2) showed the possibility of attaining specific areas of 125 m**2/m**3 and heat transfer coefficients up to 70 W/m**2 degrees K. The data obtained from these tests serve as a basis for planning industrial devices and have been used to design a prototype (exchange area : 12.5 m**2) which includes cleaning devices. The tests of this prototype carried out on a 1.6 MW boiler with fume flow rates in the range of 2000 m**3/h and outlet temperatures up to 400 degrees C showed a good agreement with the laboratory tests and demonstrated that specific heat transfers in excess of 5 kW/m**3. degrees C should be achievable, an order of magnitude better than tubular radiator-type units. A comparison of the expected cost price of the SPP unit with a number of other heat exchangers indicates that the SPP unit could be very competitive on the market for energy saving devices."
