Abstract
A flueless combustion system which accepts materials nominally designed as trash and waste, including the solid and gaseous combustion products of the system itself, and converts these materials and combustion products to marketable products. Pyrolytic conversion is employed to reform these materials and combustion products. The gaseous combustion products of this system are exhausted to an underwater distribution system which permits the gaseous combustion products to percolate through water which contains cellulosic materials to further absorb and entrap gases. The water, cellulosic materials, as well as sediments resulting from the cooling of the exhaust gases, are utilized within the pyrolytic process. The gases, steam, and heat resulting from the pyrolytic process are used in conversion processes such as the Fisher-Tropsche Process to provide marketable products. For example, the Fisher-Tropsche Process produces liquid fuels. The process utilizes the gases resulting from pyrolysis as feedstock for the reactions required to produce the liquid fuels. Residues representing only three to five percent of the materials input to the combustion system remain to be disposed of at landf…
