Description:
The need for a cost effective and cleaner method for MSW disposal hardly needs emphasizing. with EnerTech's slurry carbonization technology, liquid fuels, with a extremely low chlorine content, can be produced from RDF and are suitable for clean combustion in pulverized coal boilers. Objective of Phase I and II research is to accumulate necessary engineering data, from continuous pilot plants, to construct an integrated demonstration facility in Phase III research. In Phase II, pilot plant experiments will be continued to accumulate remaining design data and further characterize environmental emissions.In Phase I, pilot scale slurry carbonization experiments produced a slurry fuel with a HHV up to approximately 6,600 Btu/lb at 51.7 wt.% total solids and viscosity of 500 cP. Atmospheric combustion of the carbonized RDF slurry fuel produced a carbon burnout exceeding 99.9%, with excess air as low as 15%. CO emissions averaged below 16 ppm, respectively, without acid gas scrubbing. NOx emissions depended on combustion temperature and averaged between 82-211 ppm, without SNCR or SCR. In addition, mercury emissions were measured at 0.003 mg/dscm. Combustion ash was non-hazardous based on a TCLP analysis.
