Cel CURRENTLY AVAILABLE HIGH TEMPERATURE GAS/GAS HEAT EXCHANGERS HAVE SEVERAL PROBLEMS ASSOCIATED WITH THEM. FOR EXAMPLE, SOME ARE EXPENSIVE AS THEY UTILIZE SPECIAL MATERIALS TO WITHSTAND CORROSION AND OTHERS HAVE UNRELIABLE MOVING SEALS. THE HEAT EXCHANGER WHICH IS UNDER DEVELOPMENT BY STONE FLUIDFIRE CAN OVERCOME THESE PROBLEMS. IT CONSISTS OF TWO ADJACENT FLUIDIZED BEDS. THE SEPARATING WALL BETWEEN THE TWO BEDS HAS AN OPENING AT THE HEIGHT OF THE FLUIDIZED BED. THIS ALLOWS THE FLUIDIZED MASS OF THE TWO BEDS TO MAKE A HORIZONTAL CIRCULAR MOVEMENT WHICH IS INDUCED BY BLOWING HOT GAS AND COLD AIR THROUGH THE TWO RESPECTIVE BEDS WITH A HORIZONTAL COMPONENT. THE PARTITION PLATES ALLOW FREE PASSAGE OF PARTICLES FROM ONE SECTION TO THE OTHER BUT MINIMIZE GAS LEAKAGE. THE HEAT EXCHANGER OPERATES IN PARALLEL FLOW AND HAS AN EFFICIENCY OF 50 %. THE FLUIDIZED BED WILL HAVE A TOTAL AREA OF 4 M2 AND THE UNIT WILL RECOVER 530 KW OF SENSIBLE HEAT. DIFFERENT BED GEOMETRIES HAVE BEEN TRIED IN SMALL SCALE PROTOTYPES WITH GAS TEMPERATURES UP TO 250 DEGREES C WHILE TESTING WILL CONTINUE UP TO 800 DEGREES C. THE MOST APPARENT ADVANTAGE OF THIS HEAT EXCHANGER IS IT SIMPLICITY, WITH GAS LEAKAGES BEING CONTROLLED WITHIN ACCEPTABLE LIMITS. THE POTENTIAL MARKETS FOR THE HEAT EXCHANGER ARE PREHEATING OF COMBUSTION GAS AND SPACE HEATING.
