Abstract:
A recycling system for a waste converting apparatus collects residues from a post-processing means and re-introduces the residues into the apparatus such that the residues are exposed to the high temperature zone thereof.
Abstract:
A process is provided for NOx, removal at coal burning power plants, which includes introducing ammonia that is liberated upon drying a mixture of organic waste, coal combustion by-products, and optionally lime, having a pH of at least 9.5, to a coal burner in the power plant. A process is also provided for fueling a coal burner of a power plant with coal and a dried mixture of organic waste and coal combustion by-products. The present invention is further directed to the dried mixture of organic waste and coal combustion by-products made by the processes of the present invention, which may optionally be used as a soil additive or as a supplemental fuel.
Abstract:
A system and method for treating, injecting and co-combusting sludge in a municipal waste or other solid fuel combustor. The system includes a sludge receiving and treatment module and a sludge injection and combustion module. The sludge is received and stored in one or more storage hoppers where its moisture content is monitored and varied to obtain a sludge having a desired moisture content. The treated sludge is then pumped to a furnace injection nozzle where it is preferably atomized with steam and sprayed into the combustion zone of the furnace. Improved odor control in sludge handling is also provided by a storage tank and a sludge tanker trailer each having an air diffuser for mixing and aerating the sludge and a filter system for filtering odors.
Abstract:
The present invention relates to a method for treating water material containing hydrocarbon, wherein the waste material is supplied in a reactor, gas containing oxygen is supplied in the reactor, said substances are combusted to form gaseous combustion products and solid residue and said solid residue is discharged from the reactor. The gas containing oxygen is supplied continuously in the reactor in amounts insufficient for complete oxidation of the waste material, said gas containing oxygen is supplied so as to pass it through a layer of said solid residue and the gaseous combustion products are passed through a layer of untreated waste material to form a product gas containing hydrocarbons and droplets of liquid hydrocarbons.
Abstract:
PROBLEM TO BE SOLVED: To provide a reduction treatment apparatus and a reduction treatment method, capable of lowering treatment cost. SOLUTION: In a reduction oven 2 in which zinc-containing iron oxide, zinc oxide or iron oxide is supplied, at least one of waste, effective as a reducing agent, capable of generating a heat quantity necessary for reduction, and selected from the group consisting of ASR, electronic shredder dust, waste plastics, RDF obtained from wastes, RPF, sludge, oil spot, wood wastes, waste textiles, waste rubbers, and animal and plant residues, is supplied and used as a heat source to perform a reduction treatment without using an assistant fuel, thus producing metal iron by reducing zinc and/or iron oxide while contriving the reduction of treatment cost (the reduction of running cost due to avoiding the use of an assistant fuel).

Abstract:
A method controls mass and heat loading of sludge feed into a fluidized bed combustor (FBC) controlled via regulation of a polymer dosage or a sludge feed rate including: continuously monitoring at least one performance characteristic of the FBC; producing an input signal characteristic; analyzing the input signal and determining a first rate of change of the characteristic; generating an output signal based on the first rate of change to control addition of polymer to the FBC; generating a second output signal to control addition of sludge feed to the FBC; and determining a transition point between the addition of polymer and addition of sludge, which transition point is an upper limit of a first rate change to maintain flow so that the value of the characteristic is maintained proximate at the upper limit.
Abstract:
The different illustrative embodiments provide a method for processing biological material. Biological material is monitored for in a field. The biological material is retrieved from the field to form retrieved biological material in response to detecting the biological material in the field. A conversion system converts the retrieved biological material into energy. A portion of the energy is directed to a remote location. The conversion system moves in the field during at least one of the monitoring, the retrieving, and the converting.
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.
