Objective
THIS RESEARCH CONCERNS THE APPLICATION OF FLUIDIZED BED HEAT EXCHANGERS FOR HEAT RECOVERY FROM DIRTY AND CORROSIVE EXHAUST GASES. HEAT RECOVERY FROM DIESEL EXHAUST GASES OR, GENERALLY, FROM FACTORY HOT FLUE GASES CAN BE DIFFICULT BECAUSE OF PARTICLES CONTAINED IN THEM. IN CONVENTIONAL HEAT EXCHANGERS, TUBE FOULING LEADS TO A RAPID DECREASE IN HEAT EXCHANGERS EFFICIENCY, WHILE FLUIDIZED BED HEAT EXCHANGERS MAY BE ABLE TO OVERCOME THIS PROBLEM.
FIAT DESIGNED A SEMI INDUSTRIAL FLUIDIZED BED HEAT EXCHANGER PROTOTYPE OF 62 KW WHERE THE BED IS FLUIDIZED BY SOOT-BEARING EXHAUST GASES AT 500 - 600 DEGREES C OBTAINED FROM A DIESEL ENGINE. THE HEAT WAS EXTRACTED FROM THE BED BY COOLING WATER CIRCULATING IN AN IN-BED HEAT EXCHANGER. THE FLUIDIZED BED HEAT EXCHANGER HAS SHOWN VERY GOOD BEHAVIOUR BOTH FROM THE POINT OF VIEW OF HEAT EXCHANGE AND SOOT REMOVAL. MOREOVER THE ENGINE PERFORMANCE WAS BARELY AFFECTED.
EXPERIMENTS SHOWED THAT SOOT PARTICLES ARE AGGLOMERATED IN THE FLUIDIZED BED AT DIAMETERS 10 - 100 TIMES LARGER THAN THOSE AT THE ENGINE OUTLET. THE EFFICIENCY OF SOOT REMOVAL IS STRONGLY IMPROVED BY THIS AGGLOMERATION WHILE THE BED TEMPERATURE HAS A SMALL INFLUENCE ON SOOT REMOVAL EFFICIENCY. HOWEVER, THE DIESEL ENGINE AIR/FUEL RATIO STRONGLY AFFECTS THE AGGLOMERATION, AND CONSEQUENTLY THE REMOVAL EFFICIENCY, OF THE SOOT. A HIGHER AIR/FUEL RATIO RESULTS IN BETTER ADHESION OF THE SOOT TO THE HEAT EXCHANGER TUBES. THIS IS PROBABLY DUE TO THE DIFFERENT CHARACTERISTICS OF THE SOOT ITSELF AND/OR TO A HIGHER CONDENSABLE HYDROCARBON CONTENT.
A SCALED UP INSTALLATION WITH A DIESEL ENGINE OF 200 KW WITH A HEAT RECOVERY BY THE FLUIDIZED BED HEAT EXCHANGER OF 100 KW OPERATED SATISFACTORY. LONG TERM TESTING HAS NOT BEEN CARRIED OUT. YEARLY ENERGY SAVINGS WITH THIS INSTALLATION AMOUNT TO 14000 ECU. NO DATA HAVE BEEN GIVEN ON INVESTMENT AND MAINTENANCE COST.
