摘要:
A method of converting animal litter biomass into useful energy includes the steps of both combusting and pyrolising the biomass, of mixing the resultant combustible gas from the pyrolysis step with the gases from the combustion step, of igniting the mixture of gases ad and feeding the hot mixture of gases to a thermal recuperator; and apparatus therefor.
摘要:
A thermal conversion pyrolysis reactor system (10) is provided for use in providing a continuous flow type pyrolysis reaction for conversion of carbonizable input materials ("MW") (12). The reactor system (10) utilizes a diffusion material ("MD") (14) which is preheated and admixed with the MD (12) in order to facilitate pyrolysis and to partially catalyze reactions. Subsystems are provided to receive gaseous (30), liquid (32) and solid (32) phase outputs. The reactor system (10) includes further component subsystems for waste material MW input (22), MD input (26), reactor chamber (24), and heating (28). The MD (14) is preheated by being carried through the reactor chamber (64) prior to admixing with the MW (12) and further by exhaust gases (94) from the furnace space (88) being directed through a heat exchanger (126). The system (10) provides for recycling of MD (14) and is substantially self powered as a result of using combustible hydrocarbon gases produced by the pyrolysis reaction as fuel for turbulent burners (72). Input materials are evacuated of oxygen and a positive internal pressure is maintained in the reactor chamber (66) in order to maximally facilitate oxygen free pyrolysis. The system (10) is particularly adapted for use with tire chips, medical waste and industrial plastic waste input materials. Carbon black and pelletized metallic and alloy materials are preferred MD (14).
摘要:
A particulate delivery system is disclosed for particulate burners in which a hopper is provided for supplying particulate fuel to a hopper discharge opening. A rotating turntable is provided below the hopper discharge opening and includes at least one and preferably a plurality of flexible resilient vanes rotating with the turntable. A wall partially encircles the vanes and is closed on its bottom end by the upper surface of the turntable. The wall includes a lateral discharge opening that facilitates controlled discharge of the particulate fuel over the peripheral edge of the turntable. A chute receives the discharged particulate material, and drops it into a burn pot of the associated particulate burner.
