Abstract:
The present disclosure concerns a mobile device for rendering harmless organic waste, particularly medical, catering and veterinary waste, including harmful waste, to be used to render the waste harmless by means of the process of carbonization directly in the vicinity of its production. A mobile device for rendering harmless organic waste, particularly medical, catering and veterinary waste, having at least two chambers and devices to recover heat, according to the disclosure is characterized in that it constitutes a carbonization reactor unit connected at its outlet to an exhaust gases after-burning reactor, placed in a mobile container and having microwave generators as its heating devices.
Abstract:
An apparatus and methods of using the apparatus are described to decompose plastic to form a fuel for use in generating energy such as electricity.
Abstract:
A method for pyrogasification of organic wastes that employs a vertical furnace filled with metal masses in the shape of metal toroids previously raised to a high temperature (500 to 1100° C.) and organic materials to be pyrolyzed. It also employs a furnace for heating toroids transported by an Archimedes screw driven by a gear motor, as well as a separator for recovering the mineral residues, whereby separation between the toroids and residues is effected with the aid of a screen and an Archimedes screw driven by a gear motor.
Abstract:
Char-handling processes for controlling overall heat balance, ash accumulation, and afterburn in a reheater are provided. Carbonaceous biomass feedstock is pyrolyzed using a heat transfer medium forming pyrolysis products and a spent heat transfer medium. The spent heat transfer medium is separated into segregated char and char-depleted spent heat transfer medium. The char-depleted spent heat transfer medium is introduced into a dense bed of heat transfer medium fluidized by a stream of oxygen-containing regeneration gas. All or a portion of the segregated char is combusted in the dense bed using the stream of oxygen-containing regeneration gas. A portion of the segregated char may be exported out of the pyrolysis system to control the overall heat balance and ash accumulation.
Abstract:
Fuel combustion and waste conversion can be achieved by passing an axial vortex stream in a combustion chamber in a first linear direction, and passing a peripheral vortex stream as a counterflow to the axial vortex stream in a direction generally opposing the first linear direction. The peripheral and axial vortex streams can be merged so that a first fuel and oxidant in the streams at least partially combust to form a product stream, the product stream moving in the first linear direction to an outlet at the second end of the combustion chamber. Vortices can be generated by tangentially introducing fluid streams into the one or more chambers. A primary chamber, a main chamber, and an afterburner chamber can be connected in series. Second fuel and pre-chambers can be used to stabilize and enhance combustion. Reagents can be introduced to refine gaseous streams including pollutants.
Abstract:
In a method for treating alternative, carbon-containing, low-caloric waste materials for use in furnace systems, in particular rotary tubular kilns for the production of clinker, the carbon-containing, alternative fuels are subjected to high-temperature gasification under anoxic conditions at temperatures above 1000° C., wherein water, water vapor or CO2 is injected to ensure a reaction forming CO and H2. The waste heat from a clinker cooler is used for the high-temperature gasification.
Abstract:
In a combustible energy recycling system and its method, the system includes an airtight incinerator body, a gas intake module and a blower. The incinerator body is filled with a combustible waste material, and the gas intake module installed in the incinerator body includes gas intake pipes, and one of the gas intake pipes is an ignition pipe for igniting the waste material in the incinerator body for a smoldering combustion, and an air outlet pipe of the blower is interconnected to the gas intake module for guiding outside air into the incinerator body, such that the outside air can move slowly upward with a high-temperature dense smoke produced in the smoldering combustion and surround every cross-section in the incinerator body for a uniform smoldering combustion, and a gas containing combustible energy in the dense smoke can be guided to a gas recycling mechanism for recycling and reusing the gas.
Abstract:
A Pyrogen waste treatment and electrical generation combination of systems which is comprised of a combination of pyrolytic combustion systems with a feed stock and a means to convey and pre-treat the feedstock to the combustion system, where the combustion system produces a syngas; co-generators produce hot water and electrical power; and where the co-generator systems may be powered from syngas. It features a means to transfer the syngas to the cogeneration hot water and electrical power generator; a means to transfer hot water and electricity from the cogeneration hot water and electrical power generator to the pyrolytic combustion system; and a means to transfer generated electricity from the co-generator to an end user. It provides significant benefits compared to other devices and is used for a symbiotic and synergistic combination of essentially two systems—a pyrolytic combustion system and a cogeneration electrical power generator.
Abstract:
Apparatus for the pyrolysis of solid waste material includes a thermal reactor including an elongate hollow housing with a reaction chamber disposed within the housing. The thermal reactor is vertically oriented in order to cause solid waste material fed thereinto to pass through said reaction chamber by the force of gravity and a plurality of vanes are disposed for both conducting heat into said reactor chamber and for tumbling said solid waste material as said solid waste material passes through said reaction chamber.
Abstract:
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.
