Summary

AN OPPORTUNITY WAS GAINED, WHEN EXPANSION OCCURRED AT A SLAUGHTER HOUSE, OF INSTALLING ADDITIONAL 2-STAGE PLANT WHICH COULD FORM THE BASE LOAD, CONTINUOUS OPERATION, PLANT FOR THE WHOLE SYSTEM. THIS ENABLED THE SCREW COMPRESSORS USED TO BE DRIVEN BY GAS ENGINES. THE GAS ENGINES WERE COOLED BY A WATER CIRCUIT WHICH ALSO TOOK HEAT FROM THE SCREW COMPRESSOR DESUPERHEATERS AND OIL COOLERS. FINAL HEATING CAME FROM AN EXHAUST GAS HEAT EXCHANGER BEFORE THE WATER AT 361 K (88 DEG C) WENT TO STORAGE FROM WHERE IT MAY BE USED. AT CURRENT FUEL COSTS, THE HEAT RECOVERY SYSTEM SHOWED A 4 YEAR PAYBACK ON ITS HIGHER CAPITAL INVESTMENT AND HENCEFORWARD CONSIDERABLE SAVINGS. D.W.H.
