Abstract:
Waste disposal plant comprising a tank (3) for holding reactant substances (5) with a high carbon content; a tank (9) for holding dry products; a water pipe (20) for supplying the plant with water (21); a reactor (24) with a plasma torch (25); a logic control unit for channeling, to the reactor (24), controlled amounts of reactant substances, dry products and water (21), determining their disintegration through pyrolysis forming wastes (32) and a synthesis gas (31) having carbonaceous compounds, water vapour and oxygen contents measures through diagnostics means (36, 37, 39) arranged to intercept the synthesis gas (31) and controlled in feedback by the logic control unit through the controlled actuation of transport means and a valve (23) of the water pipe (20).
Abstract:
The process of the invention describes a set of steps for preparing a solid lignocellulosic biomass type feed, alone or mixed with a liquid hydrocarbon phase with a view to supplying a unit for gasification of said feed. The various steps include drying, torrefaction, milling and constituting a suspension of particles of biomass in a hydrocarbon cut.
Abstract:
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.
Abstract:
A method for processing waste material into fuel or other useful substances without polluting the air comprising the steps of: a. Introducing waste material into a storage chamber which allows the liquid to drain into a tank, b. Moving the waste to a storage chamber where it is burned, c. Moving the emissions and dust to a cleaning and burning chamber where they are further condensed, Or a. Pasteurizing sludge and raw sewage and using the gases produced for heat energy, b. Forming a solid of the liquid substances by adding ground corn and/or millet to them and using the solid for fuel.
Abstract:
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.
Abstract:
Processes and systems are provided that include introducing ammonia liberated from organic waste to a coal burner in a coal burning power plant, preferably for NOx removal at the power plant. The ammonia is preferably either ammonia liberated upon drying a mixture of organic waste and coal combustion by-products or ammonia liberated when organic waste is mixed with coal combustion by-products and one or more alkaline additives. Also provided are processes and systems of fueling a coal burner of a power plant with coal and either a dried mixture of organic waste and coal combustion by-products, or a mixture of organic waste, coal combustion by-products and one or more alkaline additives. The present invention is further directed to mixtures of either organic waste and coal combustion by-products, or mixtures of organic waste, coal combustion by-products and alkaline additives made by the processes of the present invention.

Abstract:
At least one member selected from among ASR, household electrical appliance shredder dust, waste plastic, waste-derived RDF, RPF, polluted sludge, oily sludge, waste wood, waste fiber, waste rubber and animal or plant residue as a waste matter being effective as a reducing material and functioning as a heating material through generation of an amount of heat needed for reduction is fed into a reducing furnace (2) supplied with zinciferous iron oxide or zinc oxide or iron oxide. Reduction treatment is carried out using the above member as a heat source without the use of any auxiliary fuel. Thus, zinc reduction and/or iron oxide reduction allowing production of metallic iron can be attained while realizing processing cost saving (running cost saving attributed to nonuse of auxiliary fuel).
