PARTICULATE EMISSIONS BY DIESEL ENGINES ARE A SERIOUS HEALTHHAZARD AND HAVE BEEN THE FOCUS OF RECENT EPA RULEMAKING RESTRICTING EMISSIONS BY LARGER DIESEL VEHICLE ENGINES. AVAILABLE TECHNOLOGY AND ECONOMIC CONSIDERATIONS HAVE RESTRICTED USEFUL DECISIONS ON HOW MUCH TO RESTRICT PERMIS SIBLE PARTICULATE EMISSION LEVELS. WILLIAM C. PFEFFERLE ASSOCIATES (WCP) HAS INVENTED A PROPRIETARY CATALYTICALLY- ...

STATIONARY GAS ENGINES PRODUCE A DISPROPORTIONATELY LARGE SHARE OF THE TOTAL NOX EMISSIONS IN THE U.S., BUT NO AVAILABLE TECHNOLOGY OFFERS A SATISFACTORY MEANS OF REDUCING THEIR EMISSIONS. THESE ENGINES ARE PREDOMINANTLY TWO CYCLE AND PRODUCE AN EXHAUST HAVING A HIGH RATIO OF OXYGEN (O2) TO NITRIC OXIDE (NO). THUS, A SELECTIVE NO REDUCTION TECHNIQUE IS NEEDED WHICH CONVERTS THE NO TO NITROGEN (N2) ...

N/A

THE COST OF PLATINUM AND RHODIUM IN THE THREE-WAY CATALYST ACCOUNTS FOR A MAJOR FRACTION OF THE COST ASSOCIATED WITH TREATMENT OF AUTOMOTIVE EXHAUST. THEREFORE, STRIVING TO ACHIEVE A HIGHER LEVEL OF POLLUTANT REMOVAL BY INCREASING THE PLATINUM AND RHODIUM CONTENTS IN THE THREE-WAY CATALYST IS NOT ECONOMICALLY ATTRACTIVE. IN THIS RESEARCH, AN ALTER-NATIVE METHOD FOR ACHIEVING A HIGHER LEVEL OF POLL ...

N/A

DURING HAZARDOUS WASTE INCINERATION A PHENOMENON KNOW AS PUFFING OCCURS, I.E., A LARGE AMOUNT OF ORGANIC MATTER SUDDNELY VAPORIZES IN THE COMBUSTION CHAMBER. SINCE THE SUPPLY OF COMBUSTION AIR IS NOT ADEQUATE FOR COMPLETE OXIDATION OF THIS SUDDENLY RELEASED ORGANIC MATTER, IT CANNOT BE COMPLETELY OXIDIZED, AND ESCAPES FROM THE INCINERATION IN A PUFF. THE FACT THAT COMMERCIAL HAZARDOUS WASTE INCINE ...

THIS PROJECT IS FOCUSED UPON RESOLVING THE INCOMPLETE COMBUSTION PROBLEMS ENCOUNTERED IN RESIDENTIAL WOOD STOVES DUE TO LOW COMBUSTION TEMPERATURES, UNCONTROLLED AIR DRAFT RATES, VARIABILITY IN WOOD FUEL AND MOISTURE. A PROTOTYPE RETROFIT KIT IS TO BE FABRICATED AND TESTED TO DEMONSTRATE THE FEASIBILITY OF THE DEVICE AS AN INEXPENSIVE, EASILY INSTALLABLE AND OPERABLE EMISSIONS CONTROL DEVICE THAT ...

INCREASED PUBLIC OPPOSITION TO PROPOSED PERMITS FOR LAND-BASED INCINERATOR FACILITIES AND THE GROWING MARKET TREND FOR THERMAL DESTRUCTION OF HAZARDOUS WASTES HAVE RESULTED IN A NEED FOR INNOVATIVE, COST-EFFECTIVE, AND RELIABLE TRANSPORTABLE INCINERATOR FACILITIES. THIS PROJECT PROPOSES TO ADAPT A PULSED ATMOSPHERIC FLUID-BED COMBUSTION SYSTEM FOR THERMAL DESTRUCTION OF SOLID AND LIQUID HAZARDOUS ...
