    Abstract: A waste disposal plant includes a combustion chamber (2) inside which waste laid on a combustion grate (3) is burnt. The grate permits the entrance of an adequate quantity of combustion air in the chamber through it. The combustion grate includes at least a handling group formed by fire bars or plates (7), which move alternatively one with respect to the other by advancing the waste on the grate. A handling group allows the alternate movement of the fire bars (7) which are divided in movable fire bars (7a) and fixed fire bars (7b), alternately disposed one with respect to the other, on transversal rows resting one upon the other according to a longitudinal placement with alternate steps.

  • Publication number: 20140182491
    Abstract: 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.

    Abstract: The present invention provides a burner system which uses waste fuels, especially waste plastic fuels. Burner size is minimized by having multiple combustion chambers concentrically located around a rotating screw conveyor. Heat efficiency is improved by having air passages disposed around the combustion chambers, thus preheating air for the combustion prior to its delivery to the combustion chambers, while simultaneously thermally insulating the combustion chambers against the environment. Waste fuel is transported from a fuel hopper to the combustion chambers by a rotating screw conveyor having the spiraling auger blades. Speed of screw conveyor rotation controls the consumption of waste fuel and, thus, the amount of thermal energy generated in the burner. The burner system includes an intelligent control system for controlling operation of the burner system, so that the burner system performs at optimum efficiency, safely and with minimum operator intervention.

  • Publication number: 20100089295
    Abstract: A combustion system for extracting thermal energy from biomass or other formable fuels that does not require densification or other processing of the biomass prior to combustion. This system continuously feeds the biomass fuel from an auger or other conveyance system while simultaneously causing the biomass fuel to be formed with a hollow core. The biomass fuel is ignited from within the hollow core and burns primarily radially outward due to negative pressure surrounding combustion chamber thus facilitating and containing the combustion process. This system also utilizes pre-heating the fuel, primary and secondary air pre-heating, insulated combustion chambers, and carefully control combustion air to ensure substantial combustion is achieved even with fuels having high moisture content. In the preferred embodiment, a heat exchanger is utilized to capture thermal energy of combustion products for use as an energy source for additional processes.

    Abstract: 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.
