NITROGEN OXIDE POLLUTION (NO(X)) EMITTED FROM COMBUSTORS FIRING FOSSIL FUELS (GAS, OIL, OR COAL) IS A MAJOR CONTRIBUTOR TO THE ACID RAIN PROBLEM. THE MOST EFFECTIVE TECHNOLOGIES FOR REDUCING NO(X) INVOLVE THE INJECTION OF AMMONIA (NH(3)) INTO THE FLUE GAS TO REACT WITH NO(X), RESULTING IN THE FORMATION OF INERT MOLECULAR NITROGEN (N(2)) AND WATER. THESE PROCESSES INCLUDE THE USE OF BOTH CATALYSTS ...

EMISSION OF SULFUR OXIDES (SOX) AND NITROGEN OXIDES (NOX) IN FLUE GASES IS A MAJOR CAUSE OF AIR POLLUTION AND ACID RAIN. CURRENT TECHNOLOGIES FOR SOX REMOVAL ARE EXPENSIVE AND CUMBERSOME. SULFUR DIOXIDE IS CONVERTED TO SULFURIC ACID, WHICH IS VERY CORROSIVE AND DIFFICULT TO STORE AND TRANSPORT. REMOVAL OF NOX IS ACCOMPLISHED BY CATALYTIC CONVERSION USING PLATINUM CATALYSTS. PLATINUM CATALYSTS ARE ...

AUTOMATIC PIPE WELDING, FOR BOTH NEW CONSTRUCTION AND REPAIRWELDING, CURRENTLY DEPENDS UPON OPERATOR SKILL AND OTHER CONTROLS TO ASSURE SOUND WELDED JOINTS. ADDITIONAL EXPENSESSUCH AS X-RAY INSPECTION COMBINE TO MAKE THE COSTS OF ANY NECESSARY REWORK OF WELDED PIPES PROHIBITIVE. ELECTRODYNAMIC ARC AND PUDDLE CONTROL (EDAP) IS A THROUGH-THE-ARC METHOD OF SENSING BOTH WELD PUDDLE SIZE AND PENETRATIO ...

THE AERATED FLOW COMBUSTOR (AFC) IS A NEW, ADVANCED CONCEPT OF COMBUSTOR DESIGN, APPLICABLE TO THE HIGH EFFICIENCY, CLEAN, DIRECT COMBUSTION OF COAL, COAL SLURRIES, MOST SOLID AND LIQUID FUELS, AND HAZARDOUS WASTES. AFC IS BASED UPON AN ADVANCED, INTEGRATED, INTERDISCIPLINARY COMBINATION OF TECHNOLOGIES, INCLUDING FLUIDIZED BED COMBUSTION, AERATED FLOW OF SOLIDS, AND CIRCULATION-LOOP GAS-SOLIDS CA ...
