Abstract:
A pyrolytic converter for treating waste materials has an elongated oven that has different channels. The different channels share the length of the elongated oven and divided to occupy different portions of a cross section of the oven. The pyrolytic converter also has a heating source that is configured to supply heat to a portion of the waste materials located within a channel at a specific temperature and to supply heat to another portion of the waste materials located within a different channel at a different temperature.
Abstract:
A method for conducting combustion in a fluidised bed furnace, in particular having a sand bed, according to which a flow of primary combustion air is blown through the bed, the fuel consisting in particular of organic waste, or of municipal waste, or of sludge from purifying stations, it being possible to inject secondary air (5a) into the space (5) in the furnace located above the bed; in order to limit the production of nitrogen oxides NOx and nitrous oxide N2O: the nitrous oxide N2O and nitrogen oxide NOx content of the fumes at the outlet of the furnace are measured (12, 20); the temperature of the fluidised bed is controlled to keep it at the highest admissible value at which the production of nitrous oxide N2O is substantially reduced, while the production of nitrogen oxides NOx is not substantially increased; and the excess air in the fluidised bed is controlled to keep it at the lowest admissible value at which the production of nitrogen oxides NOx is reduced without adversely affecting the combustion and the temperature of the bed.
Abstract:
The present disclosure is directed to a treatment system for medical and toxic waste. The system comprises two parts, a heterogeneous gasification system, in which syngas is produced from non-homogeneous waste, and a pyrolysis system, in which medical and hazardous waste are pyrolyzed using the syngas produced from the heterogeneous gasification system. The heterogeneous gasification system comprises a gasifier reactor having a reactor zone connected with an ash distillation zone, a re-fueling structure, an open-top water tank that wraps around the entire bottom section of the gasification system, and a gasification-agent supply module having a supply-end connected to the bottom of the gasifier reactor and a demand-end connected to the pyrolysis system. The pyrolysis system comprises a rotatable pyrolysis reactor having a horizontal and hollow cylindrical shape, a pyrolyzed-ash precipitator, which is connected to the pyrolysis reactor zone, and a condenser connected to the pyrolyzed-ash precipitator.
Abstract:
A waste melting furnace comprises: a furnace main body; an injection hole door; a discharge hole door; a dust collector; a punched plate; and an anion oxygen supply unit. The furnace main body has a waste injection hole and a cracked gas discharge hole which are formed in the top surface thereof and at least one ash discharge hole which is formed in a side surface. The injection hole door opens or closes the waste injection hole. The discharge hole door opens or closes the ash discharge hole. The dust collector is arranged in the cracked gas discharge hole and collects ashes which are contained in the cracked gas in the furnace main body so as to recover the same. The punched plate is disposed at a distance from the bottom surface of the furnace main body in the furnace main body. The anion oxygen supply unit supplies magnetized anion oxygen towards the upper side area of the punched plate which is disposed in the furnace main body.
Abstract:
The invention relates to a two stage process for the thermal treatment of wastes consisting of a batch gasification process followed by a syngas combustion process. A system and method are provided comprising of one or more first process stage batch gasification chambers (1) which are connected to a common second process stage chamber, the syngas combustion chamber, or alternatively a syngas conditioning chamber (13) and afterwards a combustion of the syngas in either a combustion chamber, reciprocating engine, boiler, gas turbine or an internal combustion device. The process can also be used to process biomass and fuels by gasification. The gasification chamber (1) has separated nozzle areas corresponding to plenum sections of the bottom where a mixture of air and recirculated flue-gas (8) is blown under the combustible material. Flue gas flow is regulated by varying the production of syngas in the gasification chambers (1) by a feedback signal from devices such as draught sensors, thermocouples, fan speeds indicators, steam flow meters, oxygen concentration meters and power production indicators.
Abstract:
A biomass energy system utilizes an automated biomass distribution system for evenly distributing biomass within a furnace of the biomass energy system. The even distribution of biomass dramatically increases efficiency of the biomass energy system. The automated biomass distribution system includes a control unit, a set of UP control boxes, and a set of valve assemblies. Each valve assembly includes a pneumatic actuator, a plug and a discharge duct matching the shape of the plug.
Abstract:
A gas processor includes a burner chamber including a first end and a second end, a gas/fuel burner having an inlet receiving air and an inlet for receiving a first combustible gas including a nozzle providing a flame extending out from the nozzle. A syn-gas chamber including injection holes and a syn-gas feed line and a syn-gas nozzle plate is coupled between the second end of the burner chamber and the gas/fuel burner including over the nozzle, wherein syn-gas is directed by the injection holes into a path of the flame for combustion of the syn-gas. An air pipe having a plurality of air discharge ports extending from the first end to within the burner chamber having an air blower coupled thereto is configured to pump air into the burner chamber.
Abstract:
An apparatus for mixing tank contents including sedimentary material is disclosed. The apparatus includes an agitator connected to a support including a plurality of detachable sections. The apparatus further includes a frame adjacent an opening in a top of the tank. The apparatus also includes an actuatable connector for interconnecting the frame to the support. The connector is configured to be actuated in order to lift a first portion of the support above the frame while a second portion of the support below the frame is maintained, to thereby cause a gap between the first portion and the second portion enabling at least one of the detachable sections to be inserted into the gap. The apparatus also includes at least one actuator for causing the connector to lift the first portion in order to cause the gap, and for lowering the first portion and the second portion.
