    摘要: A method and apparatus for providing a steam boiler/combuster and gasifier that uses a primary dirty fuel, such as waste materials, or high-polluting fossil fuels, and a secondary low-polluting fuel, such as biomass fuels for co-generation of electricity while reducing harmful emissions. The primary fuel is burned in the combuster to create steam in the steam boiler. The steam turns a steam turbine thereby powering a first generator. The dirty exhaust from the combuster is scrubbed by a gasifier. The secondary fuel and oxygen are added to the dirty exhaust in the gasifier creating gas and ash. The gas powers an engine that turns a second generator and releases a cleaner exhaust.

    摘要: A system and process to provide integrated control for the pyrolytic composition of organic (biomass) waste products especially for municipal solid waste systems. The system includes integrated control that monitors biomass waste stream throughout the entire system and the products produced therefrom and includes presorting, controlling the amount of material processed in a continuous manner, shredding, removing moisture in a continuous process that is controlled and providing the waste stream to the distillation unit for pyrolytic action where it is converted into gaseous fuel and a char residue. The gaseous fuel is scrubbed clean and monitored and stored and reused to provide heat to the system. The entire system may be self-sustaining and continuous with very little or no human intervention. An integrated real time computer control system includes sensors and measuring devices with all the major components to ensure integrated efficiency.

    摘要: A material processing apparatus includes a casing having a top and bottom and a plurality of sides defining a pyrolysis chamber for receiving and pyrolyzing feed materials therein into fluid materials and a mass of refractory material disposed upon the bottom of the casing and spaced below the top thereof and extending between its sides. The refractory mass includes an upper surface defining a bottom of the pyrolysis chamber and having an end spaced from a first one of the casing sides to define an ash residue collection cavity therebetween. The apparatus also includes a system of tunnels defined within the refractory mass being spaced below the upper surface thereof. The system of tunnels includes an inlet defined in the refractory mass at the end thereof and below the upper surface thereof and in communication with the cavity for receiving a flow of materials from the pyrolysis chamber into the system of tunnels and an outlet defined in a second one of the sides of the casing for discharging the flow of materials from the system of tunnels. The apparatus also includes elongated heater units mounted to sides of the casing and extending into and axially along selected ones of the tunnels in the system thereof.

    摘要: A waste material, particularly refuse, is conveyed through a combustion chamber while simultaneously being mixed and is treated with a gaseous oxidizing agent. The combustion chamber comprises a rotary tubular furnace. The waste material is acted on by the gaseous oxidizing agent, with the volatile combustible constituents of the waste material forming flames with the oxidizing agent. The radiation heat of the flames frees additional volatile constituents of the waste material. The waste material freed of volatile constituents is obtained as refuse coke and the unburnt volatile constituents are obtained as combustible gas. The thermal treatment in the rotary tubular furnace can be continued beyond the freeing of volatile substances. Given an adequate temperature rise, the oxidic constituents of the slag formed are melted, and the latter can be obtained in the form of glass.

    摘要: A low-temperature thermal desorption (LTTD) system remediates highly contaminated soils. The system (1) reduces the concentration of vaporized contaminants exhausted from the primary treatment unit (PTU) and (2) precisely controls the concentration of vaporized contaminants exhausted from the PTU so as to permit the safe oxidization of contaminants in a secondary treatment unit without oversizing the secondary treatment unit or the baghouse. The concentration of vaporized contaminants exhausted from the PTU is reduced by drawing the vaporized contaminants into a low-pressure region of the PTU so as to contact the burner flame and by supplying this area of flame contact with a modulated supply of air to oxidize a designated portion of the vaporized contaminants within the PTU. The concentration and temperature of the remaining vaporized contaminants are controlled by monitoring the concentration of the contaminants in the gas stream exhausted from the PTU, by calculating a lower explosive limit (LEL) of the contaminant concentration, and by providing a modulated supply of heated dilution air to the gas stream to precisely reduce contaminant concentration levels in the gas stream to a desired percentage of the calculated LEL.
