연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A pyrolysis oven configured for vertical conveyance of material for incineration. The oven makes use of gravity and multiple plates to control the movement of material through the oven chamber. The plates and oven interior are heated in a low oxygen, pressurized environment to effect the decomposition of material as it freefalls down the chamber and makes contact with heated plates. The configuration and angle of declination of plates determines the freefall rate and retention time within the incinerating environment. The decomposition produces char and gas resultants, each of which are carried off through separate exits configured in the oven. The oven may be used as part of a waste management system in connection with a thermal oxidation chamber for the treatment of volatile organic compound gases that are a by-product of the pyrolytic process.

We claim: 1. A vertical retort oven for thermal conversion of material, comprising: a heating shell chamber including an interior wall surface; a reaction vessel including an exterior wall surface and an interior having an interior wall surface and positioned within the heating shell to define a cavity formed between the heating shell interior wall surface and the reaction vessel exterior wall surface, the reaction vessel further including an inlet; a plurality of plates positioned within the reaction vessel interior to direct the freefall of material from the inlet through the reaction vessel interior; a heat source positioned within the cavity; and means for transmitting heat from the heat source to the reaction vessel interior; wherein: the plates have a mounted end and have an opening at the mounted end, and the reaction vessel includes thermal energy ports disposed in alignment with openings on the mounted plate ends; the reaction vessel includes a gas exit coupled to a gas discharge conduit configured to project outward from the gas exit, through a cavity between the reaction vessel and the heating shell, and through the surface wall of the heating shell; the gas discharge conduit further comprises a pipe leading back into the heat source for supplying the heat source with the gas expelled by the oven through the gas exit; the plates are arranged vertically in overlapping succession and positioned to direct materials from one plate to succeeding lower plates; the plates are mounted adjustably hinged to the reaction vessel interior wall surface; and a bolt hinge including a first closed end, a second open end and a hollow shaft, the shaft including bores positioned along the shaft, the bolt hinge pivotally connecting respective plates to the reaction vessel interior wall surface and configured to permit heat from the heating shell to travel through the bolt open-end and through the shaft into respective plates. 2. A system of processing material through thermal conversion and combustion, comprising; a vertical retort oven including a reaction vessel with at least one interior wall surface defining a reaction vessel interior, an inlet, and a material exit, the reaction vessel housed at least partially within a heating shell forming a cavity therebetween, a heat source positioned within the cavity for heating the cavity and reaction vessel interior, a series of plates mounted to the reaction vessel interior wall surface and positioned to angle downwardly and inwardly therefrom to thermally convert the material dropped in through the inlet whereby entering the reaction vessel interior and contacting the plates thermally converts the material resulting in char and gases, the plates configured to direct the char to the material exit, a gas outlet positioned on the reaction vessel interior wall surface and coupled to a pipe configured to project out of the heating shell for expulsion of gas; a thermal oxidation chamber comprising a gas entrance and a burner for the combustion of gases expulsed from the vertical retort oven; and a gas discharge conduit coupled to the pipe between the vertical retort oven gas outlet and the thermal oxidation chamber gas entrance whereby the gases produced from thermal conversion of material in the vertical retort oven are communicated into the thermal oxidation chamber through the conduit; wherein the reaction vessel interior wall surface includes a plurality of slots each adapted to receive a respective plate, whereby the plates may be selectively spaced within the reaction vessel interior; and the system includes slot covers for covering slots into which plates have not been inserted. 3. The system for processing material of claim 2, wherein: the thermal oxidation chamber is set at a lower pressure in the system than the vertical retort oven. 4. The system for processing material of claim 2, wherein: the thermal oxidation chamber is cyclonic. 5. The system for processing material of claim 2, further comprising: a secondary heat source line; a heat exhaust port on the oxidation chamber coupled to a first end of the secondary heat source line; a secondary heat source port formed through the walls of the heating shell coupled to a second end of the secondary heat source line whereby a secondary heat source for the vertical retort oven is formed from a heat expelled from the combustion of gases within the thermal oxidation chamber. 6. The system for processing material of claim 2, wherein: a reaction vessel interior is maintained within a vacuum environment. 7. The system for processing material of claim 2, further comprising: a condenser in operative connection to the pipe wherein the gases are removed from the oven and condensed into oils in the condenser. 8. A vertical retort oven for thermal conversion of material, comprising: a heating shell chamber including an interior wall surface; a reaction vessel including an exterior wall surface and an interior having an interior wall surface and positioned within the heating shell to define a cavity formed between the heating shell interior wall surface and the reaction vessel exterior wall surface, the reaction vessel further including an inlet; a plurality of plates positioned within the reaction vessel interior to direct the freefall of material from the inlet through the reaction vessel interior; a heat source positioned within the cavity; and means for transmitting heat from the heat source to the reaction vessel interior; wherein: the plates are mounted adjustably hinged to the reaction vessel interior wall surface; and the oven further comprising bolt hinges pivotally connecting respective plates to the reaction vessel interior wall surface. 9. A vertical retort oven for thermal conversion of material as defined in claim 8, wherein the bolt hinges each include a first closed end, a second open end and a hollow shaft, the shaft including bores positioned along the shaft, the bolt hinges configured to permit heat from the heating shell to travel through the bolt open-end and through the shaft into a respective plate.
