Abstract

THIS REPORT PRESENTS THE MOST IMPORTANT RESULTS OF A DEMONSTRATION PROJECT TO ESTABLISH A FOUNDRY SANDS THERMAL REGENERATION PROCESS WITH LOW RUNNING COSTS, THROUGH HIGH ENERGY RECOVERY AND REASONABLE INVESTMENT COSTS. THIS UNIT IS A SINGLE COLUMN SATURNE TYPE, INCLUDING FLUIDISED BED AND DOUBLE GAS/SOLIDS HEAT RECOVERY UNITS. THE ENERGY SAVED IS AT LEAST 0.02 TOE PER MTON OF SAND, SO THE COST SAVING PER TON OF SAND CAN BE AS HIGH AS 200-250 F FR, DEPENDING ON THE NEW SAND PRICE AND ON THE DUMPING COSTS OF THE USED SANDS. THE GROSS ROI TIME IS BETWEEN 1.25 AND 2.5 YEARS, WITH REFERENCE TO THE INDUSTRIAL OPERATING TIME (3600 HOURS TO 7000 HOURS/YEAR).
