    摘要: A process of making a fuel product from spent grain from a beer brewing process. In the brewing process, the grain is pulverized to a particle size whose mean particle size is approximately 0.25 mm to 0.6 mm with less than 1% greater than 2 mm. After the brewing sugars are extracted from the grain, the spent grain is pressed against a filter to reduce moisture below sixty-five percent (65%), and then the grain is dried to further reduce its moisture to less than ten percent (10%). The dried spent grain, after the aforementioned processing, is fed into a combustion chamber for a steam boiler that is used for beer brewing, and the spent grain is separated during combustion by agitation such as spraying of the grain in the combustion chamber.

    摘要: A process of making a fuel product from a non-combustible high protein organic material such as a biological by-product or waste material. The moisture content of the high protein organic material is mechanically reduced and dried to reduce the moisture content to less than ten percent (10%). The high protein organic material is pulverized to a particle size of less than about 2 mm. The high protein organic waste material is fed into a combustion chamber and separated during combustion such as by spraying high protein organic waste material within the combustion chamber. Temperature and combustion reactions within the combustion chamber are controlled by controlling the moisture in the combustion atmosphere and energy injections at or downstream of the combustion chamber. The concentration of protein thermal decomposition by-products, temperature, and residence time and/or additions of energy plasma within the combustion chamber environment are controlled to degrade hazardous polyfluoro compounds.

Temperature and nitrogenous hydrocarbon combustion reactions within the combustion chamber are also controlled by injection of steam within the combustion chamber. The concentration of protein thermal decomposition by-products, the temperature and/or pressure within the combustion chamber is also controlled to degrade hazardous polyfluoro compounds into less hazardous compounds.
