摘要:
Reactors for conducting thermochemical processes with solar heat input, and associated systems and methods. A system may include a reactor having a reaction zone, a reactant source coupled in fluid in communication with the reactant zone, and a solar concentrator having at least one concentrator surface positionable to direct solar energy to a focal area. The system can further include an actuator coupled to the solar concentrator to move the solar concentrator relative to the sun, and a controller operatively coupled to the actuator. The controller can be programmed with instructions that, when executed, direct the actuator to position the solar concentrator to focus the solar energy on the reaction zone when the solar energy is above a threshold level, and direct the actuator to position the solar concentrator to point to a location in the sky having relatively little radiant energy to cool an object positioned at the focal area when the solar energy is below the threshold level.

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.

Methods and products for cleanup of fluid medical waste. In one illustrative embodiment, a product may include coconut coir in a loose granulated grade, a compressed pellet grade, or mixture thereof allowing users to choose between grades more ideal for their application while achieving the same results of absorbing and solidifying all human waste and fluids for safe removal and disposal. In a second illustrative embodiment, a product may include coir in a proportion of from about 85% to about 99% and a suitable microbe for initiating bioremediation in an appropriate form in a proportion of from about 20% to about 1%, by weight.
摘要:
Improved combustion of biomass is achieved by injected first and second streams of biomass from a burner where the first stream of biomass has a median particle size larger than the biomass of the second stream and oxygen is injected with the first stream to provide an oxygen-enriched environment around the larger median sized particles. The oxygen-enriched environment is achieved either by injecting the oxygen directly into the first stream or by premixing the oxygen with the conveying air of the first stream.

A municipal or like refuse is crushing, separating ferrous metals, mixing with crushed limestone, drying up and loading in furnace of pyrolysis. An electronic and electric scrap is crushing, drying up from surface water and warming on 2-4° C. above temperature of transporting air, divide into concoction nonferrous and precious metals and dielectric fraction, which go in furnace of pyrolysis by specified air, cleaned from dust and moistened up to 100% moisture by water. At mixing with dielectric fraction temperature of the air increases, relative moisture falls down to level, excluding condensation of moisture and spark formation in system. Pyrolysis is carried out under simultaneous neutralization of allocated hydrogen chloride by limestone with reception of calcium chloride. Gas allocated at pyrolysis condensing and dividing to water and organic phases (liquid fuel). Solid products of pyrolysis together with ash and slag supplied from landfill blade of heat power station, washing by specified water phase for dissolving of calcium chloride and extracting ions of heavy metals, then centrifuging. Filtrate and washing water cleanse from heavy metals. Solid products of pyrolysis move for incineration in combustion chamber. Combustion chamber slag, cleanse from heavy metals and not burned-out fuel in slag of heat power station, cool by air, which is then used in combustion chamber. Slag concrete products expose by the thermohumid processing by part of humid chimney gases after drying the calcium chloride, the other part gas is going to production of the carbonic acid.
摘要:
Process for solid waste treatment, and particularly municipal solid waste, with recovery of the thermal energy, which is based on the general pyrolysis process modified in order to improve, on the one hand, the energy yield and, on the other, to reduce the quantity of unusable solid residues to be sent to the waste disposal, the unusable solid waste being limited to 10-15% of the total weight of the initial residue. The process and relative plant include a boosted treatment of the incoming waste, with a preliminary separation into three solid fractions, the first one of which is separately subjected to a preliminary drying step and the third one undergoes further shredding. The process and relative plant also include a section for recovering energy from the pyrolysis coke, wherein the latter is subjected to a thermochemical treatment with the production of a further quantity of synthesis gas.

摘要:
There is provided a method of incinerating a waste material to process incineration residues produced in a gasification furnace easily with existing equipment. A combustible gas generated when a waste material A is dry-distilled in a gasification furnace 1 is introduced into a combustion furnace 3 and combusted therein. The combustible gas is generated in the gasification furnace 1 in order to keep the temperature in the combustion furnace 3 at a temperature capable of melting incineration residues. The incineration residues are charged into the combustion furnace 3 while the combustible gas is being combusted therein, and melted into a melted material B that is discharged from an outlet 3 of the combustion furnace 3 into a receptacle 33 in which the melted material B is solidified. Air supplied to an air jacket 6 and oxygen supplied to the gasification furnace 1 and the combustion furnace 3 are heated by a heat exchange with waste gases from the combustion furnace 3. The heat exchange is carried out by providing a heat exchanger 36 with a conduit 8 disposed therein in a passage of the waste gases from the combustion furnace 4, and passing air or oxygen through the conduit 8 upstream in the passage of the waste gases.
摘要:
Process and plant for producing a refuse derived solid fuel (RDSF), including a first component having a dry fraction of a solid urban waste (MSW) in a shredded form and at least one second component in a shredded form selected from an elastomeric material and a thermoplastic material, or mixtures thereof, wherein the dry fraction of the MSW, the elastomeric polymer material and/or the thermoplastic polymer material are stored in separate containers and when required are metered and fed in subsequent layers onto a continuous conveyor which discharges into a temporary accumulating container, for example, the box body of a motor vehicle, intended to directly feed the combustion plant wherein the RDSF is burned. In this way, there is no need to premix the various fractions of the RDSF during the production stage and to maintain the resulting mixture constantly stirred in order to prevent compaction and/or separation of fractions. In fact, mixing between the various fractions only takes place at the end of the production process when the RDSF is placed in the temporary accumulation container which feeds the combustion plant.
摘要:
Solid combustible waste materials are converted into highly efficient fuel by subjecting such materials to size reduction in suitable size-reducing equipment. The last piece of the equipment is a mill which pulverizes the waste materials into fine particles having a high surface to mass ratio and forming a highly efficient fuel when these particles are directly injected into a combustion reactor operating at high temperature.
