Phase: II
Project Period: September 1, 1991 through June 1, 1993

Description:

Sonotech, Inc., in Phase II proposes to build on the success of its Phase I efforts which demonstrated that an incinerator's performance can be improved significantly by retrofitting it with a tunable pulse combustor which excites pulsations inside the incinerator. These pulsations increase the rates of heat, mass, and mixing processes which, in turn, improve the incineration process performance. The Phase I tests, conducted with surrogate wastes, have demonstrated that pulsations decrease exhaust soot emissions, improve high destruction and removal efficiencies (DRES) of princi- pal organic hazardous constituents (POHCs), and improve efficiency of oxygen use. The goal of Phase II will be to obtain additional design data and develop a liquid fuel-fired pulse combustor which are needed for commercialization of the technology with von Roll, a major incinerator systems manufacturer. To meet these goals, Task 1 will determine the benefits of pulse combustion technology in batch type Incineration of various surrogate wastes. Task 2 will de- velop a liquid fuel-fired tunable pulse combustion needed for the commercialization of the technology, and Task 3 will determine the benefits provided by the developed liquid fuel pulse combustor during steady incineration of contaminated liquid fuels which will be also used to fire the pulse combustor. In summary, Phase II will develop an extensive design and incineration data base and a liquid fuel-fired pulse tunable combustor needed for commercial- ization of the developed pulse combustor technology with von Roll under Phase III of this progrwn.
