Cel THERE ARE CONSIDERABLE TECHNICAL AND ECONOMIC BENEFITS TO THIS RESEARCH PROJECT. IN MODERN INTEGRATED STEELWORKS THERE HAS RECENTLY BEEN AN INCREASE IN COAL INJECTION PRACTICE INTO BLAST FURNACES. THIS HAS RESULTED IN A LOWER SPECIFIC PRODUCTION OF RICH FUEL (COKE OVEN GAS) COMBINED WITH A STEADILY FALLING CALORIFIC VALUE OF THE LEAN FUEL (BLAST FURNACE GAS). THE RESULT OF THE TREND IS THAT MANY INTEGRATED STEELWORKS NOW IMPORT EXPENSIVE RICH FUELS SUCH AS NATURAL GAS OR OIL FOR THEIR HIGH TEMPERATURE REHEATING PROCESSES WHILST THE BLAST FURNACE GAS IS ONLY FIT FOR STEAMRAISING. A CONSIDERABLE QUANTITY OF THIS STEAM CAN ONLY BE UTILIZED FOR ELECTRICAL GENERATION, USUALLY AT POOR EFFICIENCIES (AND THUS POOR ECONOMY) COMPARED WITH NATIONAL GRID SYSTEMS. SINCE THESE GRID SYSTEMS USUALLY HAVE AN INCREASING NUCLEAR COMPONENT IN THEIR GENERATION FACILITIES, IMPORTED ELECTRICITY COSTS ARE FALLING VIS-A-VIS RICH FUELS. THESE TRENDS TAKEN TOGETHER POINT TO THE UTILIZATION OF BLAST FURNACE GAS IN HIGH TEMPERATURE PROCESSES AS THE ONLY SOLUTION TO THIS TECHNICAL AND ECONOMIC IMBALANCE. WHILST BLAST FURNACE GAS PERFORMANCE CAN BE RAISED BY COMBUSTION WITH OXYGEN, ENRICHING NATURAL GAS TEC. THESE MEASURES CAN ONLY BE PALLIATIVES. THE USE OF DOUBLE-REGENERATIVE BURNERS CAN PRODUCE THE FLAME TEMPERATURES NECESSARY FOR REHEATING FURNACE (> 2000 C) WHILST OFFERING A THERMAL EFFICIENCY EQUAL TO OR BETTER THAN THE VERY BEST OF CURRENT PRACTICE ON RICH FUELS, AND CONSIDERABLY BETTER THAN CURRENT AVERAGE PRACTICE ON RICH FUELS, UP TO A 30% ADVANTAGE IN FURNACE FUEL CONSUMPTION. THE PURPOSE OF THIS RESEARCH IS TO ACQUIRE THE ABILITY TO UTILIZE BLAST FURNACE GAS IN HIGH TEMPERATURE (1250 C) PROCESSES SUCH AS IN REHEATING FURNACES. THIS IS TO BE DONE BY EXTENDING THE PRINCIPLE OF REGENERATIVE BURNERS IN WHICH COMBUSTION AIR IS PREHEATED BY MEANS OF A SMALL, RAPID REVERSAL REGENERATOR TO THE PREHEATING OF BOTH THE COMBUSTION AIR AND THE BLAST FURNACE GAS. THIS RESEARCH PROGRAMME IS TO FIND SOLUTIONS TO THE FOLLOWING ENVISAGED DIFFICULTIES: 1. FLAME INSTABILITY AT COLD LIGHT-UP 2. PRODUCTION OF A SATISFACTORY FLAME ENVELOPE SHAPE 3. WHEN THE BURNER IS IN THE REGENERATION PHASE, TO BALANCE THE FLOWS THROUGH EACH REGENERATOR TO OPTIMIZE THERMAL EFFICIENCY 4. TO EVOLVE APURGING PROCEDURE OF THE BLAST FURNACE GAS FROM ITS REGENERATOR PRIOR TO REVERSAL, SO AS TO MINIMISE BOTH LOSS OF FUEL GAS AND CARBON MONOXIDE EMISSIONS. 5. TO STUDY THE EFFECT OF IMPURITIES IN THE GAS ON THE REFRACTORY COMPONENTS OVER AN EXTENDED TRIAL PERIOD.
