    Abstract: A system and method for treating, injecting and co-combusting sludge in a municipal waste or other combustor is disclosed. 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 it is first diluted with a liquid and subsequently mixed to a desired homogeneous consistency suitable for pumping. The high liquid content 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. The disclosed system and method increases sludge moisture content and controls the solids content of the sludge to control furnace temperature.

    Abstract: A system and method for drying, cleaning and upgrading coal and biomass solid fuel while integrating the steps with the normal on site steps in coal preparation for a utility boiler, such that boiler efficiency is improved and emissions are reduced. The present invention carefully sequences steps to employ latent heat from one step to the next and more efficiently bring the fuel up to or near ignition temperature. The present invention incorporates several previously related inventions to improve the heat content and cleanliness of the fuel, thus reducing fuel flow rate, ash, CO2, CO, NOx, sulfur, mercury, chlorine, particulate and other emissions, for the same or higher energy output.

    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: A reduction treatment apparatus can include a reduction furnace configured to reduce zinc and/or iron oxide through heat treatment of zinc-containing iron oxide or zinc oxide or iron oxide, with a reducing material. The reduction treatment apparatus also has an oxide inlet configured to supply to the reduction furnace the zinc-containing iron oxide or zinc oxide or iron oxide. The reduction treatment apparatus further has a reducing material inlet configured to supply to the reduction furnace the reducing material. The reducing material can comprise at least one of ASR, shredder dust of home electric appliances, waste plastics, refuse derived fuel, refuse paper and plastic fuel, sludge, oil mud, chips of wood, thread debris, rubber debris, and animal and plant residues. The reduction furnace can be configured to use the reducing material as a heating material and reduce the zinc-containing iron oxide or zinc oxide or iron oxide without auxiliary fuel.
