Resumen
AN EVALUATION OF THE ENERGY POTENTIAL OF ORGANIC WASTE CALLED SLUMGUM, GENERATED IN THE BEE-WAX INDUSTRY, IS DEVELOPED. THE MAIN OBJECTIVE IS TO DETERMINE WHETHER THIS WASTE CAN BE USED AS FUEL TO GENERATE THE STEAM REQUIRED IN THE PLANT, CONSIDERING ITS COMBUSTION IN A FLUIDIZED BED BOILER. CURRENTLY, THERE ARE NO STUDIES IN THE LITERATURE ASSOCIATED WITH THE USE OF SLUMGUM FOR ENERGY PURPOSES; ONLY ITS USE FOR AGRICULTURAL PURPOSES IS STUDIED, THUS HIGHLIGHTING THE NOVELTY OF THE PRESENT RESEARCH. THE SLUMGUM S MAIN PHYSICAL?CHEMICAL AND ENERGY PROPERTIES ARE DETERMINED, COMPLEMENTING THE INFORMATION AVAILABLE IN THE LITERATURE AND MATHEMATICAL CORRELATIONS, OBTAINING A HIGHER HEATING VALUE OF 17,076 MJ/KG IN THE DRY BASE. AN ENERGY BALANCE WAS MADE IN THE BOILER, CONSIDERING A BUBBLING FLUIDIZED BED SYSTEM S OPERATING CONDITIONS. RESULTS SHOW THAT FOR TYPICAL TEMPERATURE VALUES IN THE HEARTH OF 850 °C AND EXCESS AIR OF 20%, ONLY 25% OF THE HEAT RELEASED IN COMBUSTION IS USED TO GENERATE STEAM; THE REST IS LOST AS SENSIBLE HEAT IN THE EXHAUST GASES. THE PLANT S STEAM DEMAND COULD BE FULLY SATISFIED USING THE SENSIBLE GASES HEAT, FEEDING 1.778 KG OF SLUMGUM OF 8.000 KG PRODUCED DURING THE ALL SEASON, INDICATING THAT 77% OF THE FEEDSTOCK REMAIN AS ENERGY RESERVE. THE PROPOSED PROCESSS ENERGY-ECOLOGIC-EFFICIENCY IS 0,8; THE ECONOMIC SAVINGS OBTAINED BY FUEL REPLACEMENT, TAKING NATURAL GAS AS A REFERENCE, CORRESPONDS TO 716 USD PER SEASON.
