  • SDW solid domestic waste
  • coals coals
  • oil-slime biologic mass
  • a scheme of gasifying solid organic fuels in countercurrent flow to a gasifying agent can be generally described as follows.
  • An oxygen-containing gasifying agent which possibly containing water and/or carbon dioxide are supplied into a combustion zone where oxygen reacts with carbon in a solid fuel in the form of coke or semi-coke at temperatures about 900-1500°C.
  • the gasifying agent is admitted into the reactor in countercurrent flow to the fuel so that at least part of the oxidizing gas is preliminary passed through a layer of hot solid combustion products that are already free from carbon. In this zone the solid combustion products are cooled and the gasifying agent is heated prior to entering the combustion zone.
  • RU-2-062284 (Manelis et al. ) discloses processing worn automobile tires; RU-2079051 and RU-2152561 (Manelis et al. ) disclose processing solid domestic waste, oil-slime and similar oil waste.
  • solid lump inert material is introduced into a reactor along with the processed fuel to provide, in particular, uniform gas permeability of the feed in the reactor.
  • Kiln gas preferably mixed with air, is used as a gasifying agent, the kiln gas portion in the gasifying agent being increased when the temperature in the combustion zone exceeds 1300°C, and reduced when the temperature in the combustion zone falls below 800°C.
  • a method of gasifying wastes is proposed in US 4,732,091 (Gould ).
  • the method comprises introducing a solid fuel into an upper section of a shaft kiln.
  • the fuel is caused to move at a controlled rate through a series of chambers horizontally separated by moveable grates, where the fuel is pyrolyzed and burned in countercurrent flow of a vapor/air gasifying agent.
  • the method includes loosening the waste in the course of treatment to provide uniform gas permeability and uniform movement of the processed feed material successively to drying, pyrolysis, gasification and cooling zones.
  • a method is also proposed for controlling the fuel entry into respective zones.
  • the prior art method suffers largely from the presence of moveable grates.
  • the moveable grates will be inevitably worn fast in high-temperature zones.

  • Rotary kilns are also widely known. They are extensively used for burning cement and combustion of waste. Kiln rotation provides uniform mixing of the material processed. A rotary kiln is known to be used for gasification process, e.g. as taught in US 247,322 issued 30 September, 1881 .
  • Application US-2005051066 discloses a method of gasifying a solid fuel in a parallel gas/solid flow using a rotary kiln.

  • the material which is introduced at a temperature below 600°F (315°C) passes through pre-heating and devolatilizing zones and is gradually heated to 1600°F (871°C); at this temperature the material loses its caking tendency and then enters a gasifying zone, where a vapor-containing oxidizing medium is admitted under the mixed layer, this resulting in formation of combustible gases containing hydrocarbon that are removed from the kiln side where the fuel is fed.
  • the object can be attained in a method for gasifying condensed fuels.
  • the present invention provides a method for processing a condensed organic fuel by gasifying, including: feeding a fuel into a cylindrical reactor; supplying an oxygen-containing gasifying agent into the reactor at the reactor side where the resultant residual solids accumulate; moving the fuel feed along the reactor axis; discharging the resultant residual solids from the reactor; driving-off the products of drying, pyrolysis and combustion as a gas product from the reactor such that gasification is carried out as the fuel successively resides in a heating/drying zone, a pyrolysis zone, a combustion (oxidation) zone and a cooling zone, and the gas flow is filtered through the fuel feed layer while passing successively through the cooling zone, the combustion zone, the pyrolysis zone and the heating/drying zone.
  • the important distinctive feature of the invention is that the combustion process in the dense layer is stabilized by rotating the reactor about an axis tilted relative to the horizon, at an angle in the range of from 40 to 65 degrees.
  • Fig.1 is a general schematic diagram of a device for implementing an embodiment of a method in accordance with the invention.
  • a method in accordance with the invention includes the following basic steps that are implemented in respective zones.
  • a condensed fuel in solid, liquid of paste state possibly including solid noncombustible components and moisture (hereinafter referred to as "fuel") is fed into a reactor to successively perform therein drying the fuel and then pyrolysis/gasification of combustible constituents of the fuel.
  • An oxygen-containing oxidizing gas e.g. air
  • Fuel passes through a number of zones in the reactor, as described below.
  • the fuel passes through a drying zone where the fuel temperature increases to 200°C owing to the heat exchange with the flow of gas product filtering through the fuel; in this zone the fuel is dried, and the gas flow is cooled before driving-off the latter from the reactor.
  • a drying zone where the fuel temperature increases to 200°C owing to the heat exchange with the flow of gas product filtering through the fuel; in this zone the fuel is dried, and the gas flow is cooled before driving-off the latter from the reactor.
  • gaseous products of drying, pyrolysis and gasification are removed from the reactor.
  • the fuel enters the pyrolysis and coking zone where the temperature increases gradually to 800°C owing to the heat exchange with the gas flow, and combustible constituents of the fuel are pyrolyzed to produce coke.
  • the coked fuel enters then a combustion and gasification zone, where the solid phase has a temperature of 700-1400°C.
  • the coke reacts with the hot oxidizing gas to produce a fuel gas.
  • Residual solids enter a cooling zone where they are cooled by the counter flow of the gasifying agent from the combustion temperature to a discharge temperature.
  • the oxidizing gas counter flow, filtering through the dense layer of residual solids, is in turn heated to a temperature close to the combustion temperature before it enters the combustion zone.
  • zones may be defined differently, e.g. based on the gas temperature, content of agents, etc. In particular, in US-A-4,732,091 the same zones are referred to differently.
  • the essential feature is that in the countercurrent interpenetrating flows of gas and solid feed material the oxidizing gas (gasifying agent) is pre-heated on residual solids, and hot gaseous combustion products will further transfer their heat to the raw fuel.
  • the invention allows the efficient inter-phase heat exchange that is advantageously provided by the process in the dense layer to be combined with mixing the processed material by action of gravity as the reactor rotates, which is typical to rotary kilns.

  • An oxygen-containing gasifying agent is supplied into the reactor section where the resultant residual solids accumulate, and the fuel is gasified in the reactor by successively passing through the zones of drying, pyrolysis, combustion, gasification and cooling in a gas flow filtering through the dense fuel layer countercurrent to the fuel movement along the reactor axis with a predetermined time of holding in each of the zones.
  • the cylindrical reactor is mounted with its axis tilted at an angle relative to the horizon and rotated such that the material pours in the direction perpendicular to and along the reactor axis and fills the voids formed when the low-density material bums out.
  • the gasifying agent is supplied at the bottom end of the cylindrical reactor, while the gas product is removed at the opposite end.
  • the cylindrical reactor axis is tilted at an angle from 40 to 65 degrees relative to the horizon. With a tilt angle below the lower limit, bulk material will not form a dense layer in the tilted reactor. On the opposite, a layer of solid fuel will be formed with a gas flow above it. The gas flow is not filtered through the fuel, consequently the main advantage of gasification in a dense layer, highly efficient inter-phase heat exchange, will not be realized, as well as uniform process will not be provided over the reactor section. With a tilt angle above the aforementioned range the solid material will not be adequately mixed in case of "burnouts".
  • Optimum combination of conditions for the fuel movement along the reactor axis and uniform combustion zone structure will be attained with a tilt angle of the reactor axis relative to the horizon from 40 to 50 degrees.
  • the reactor rotation period should be sufficiently small to provide mixing of materials in the combustion zone. This will enable the invented process to be implemented in a reactor having a smaller length.
  • a sufficient rotation speed of the reactor must be provided. If the bulk velocity of discharging the residual solids is V,(m 3 /h), the average time of holding the residual solids in the combustion zone will be about ⁇ D 3 /4V (hour).
  • Reactor rotation period T should be preferably no more than approximately D 3 /4V (hour) to provide no less than triple mixing of the material for the time when it stays in the combustion zone.
  • the fuel processed is preferably a solid lump material which is sufficiently permeable to the filtering gas flow. If the fuel is insufficiently permeable, in particular, when fine-dispersed, liquid or paste fuels are processed, a noncombustible solid lump material is fed into the reactor along with the fuel to provide uniform gas permeability of the fuel feed in the reactor and improve conditions of mixing the material in the combustion zone in case of burnouts.
  • a noncombustible solid lump material is fed into the reactor along with the fuel to provide uniform gas permeability of the fuel feed in the reactor and improve conditions of mixing the material in the combustion zone in case of burnouts.
  • liquid or paste materials it is not obligatory to preliminary mix them with a solid lump material before feeding into the reactor, because uniform mixing will be provided by the reactor rotation.
  • the solid inert material added to the feed should preferably have a density different from that of the processed fuel.
  • the process is performed in a device for gasifying a condensed solid fuel including a feeder, a cylindrical reactor, a discharge unit, a gasifying agent supply unit, a gas product outlet, a driver for rotating the reactor, seals to provide gas tightness in the reactor rotation, wherein the cylindrical reactor is mounted such that its axis is tilted at a tilt angle from 40 to 65 degrees relative to the horizon; the feeder and the gas product outlet are arranged in the upper section of the reactor, while the discharge unit and the gasifying agent supply unit are arranged in the lower section of the reactor.

  • the holes in the reactor side surface are preferably equipped with free passage control means, such as controlled shutters.
  • the reactor can be discharged through a cone having an opening along the reactor axis, the cone secured in the lower section of the reactor, the opening diameter being smaller than half the internal diameter of the reactor.
  • the cylindrical reactor should have a sufficient length. To arrange the respective zones in the reactor, the following relationship between geometrical dimensions of the reactor should be observed: L ⁇ sin ⁇ > 3 ⁇ D ,
  • the use may made of both measuring the actual level (e.g. by a radiation sensor) and outputting a command to introduce the next portion of the fuel, and a feeder including a vertical cylinder having a smaller diameter than that of the rotary reactor, the lower end of the cylinder extending inside the upper section of the reactor.
  • the feeder maintains a constant level of the fuel feed in the reactor at the expense of pouring the fuel out from a vertical tube as the fuel is consumed in the reactor.
  • Condensed fuel F previously milled, if necessary, and to which a noncombustible solid material is added when needed, is introduced into a reactor 1 through a feeder 2 comprising a feed-lock chamber 3.
  • the fuel enters the reactor through a vertical cylinder 4.
  • the processed fuel level is maintained constant in the reactor owing to pouring the fuel out from the cylinder 4 as the reactor 1 rotates and filling in the material consumed in combustion and removal of ashes.
  • the material passes successively through a drying zone 4, a pyrolysis zone 6, a combustion zone 7 and a cooling zone 8.
  • residual solids R pour out through holes 9 equipped with shutters 10, and then they are discharged, continuously or in batches, through a gas-tight discharge unit 11 (a hydraulic lock shown schematically in the drawing).
  • a discharge velocity of the residual solids at which the combustion zone maintains the same position in the reactor, in the middle section of the reactor, is provided by the relationship between free passages of the holes 9, rotation speed of the reactor and consumption of an oxidizer admitted into the reactor.

  • a level sensor monitors whether the amount of fuel is sufficient in the feeder, and as the fuel is exhausted fresh portions are fed via the feed-lock chamber 3. To match the discharge velocity of residual solids, free passages of the holes 9 are adjusted: they are increased when the discharge velocity exceeds a desired one, and reduced in the opposite case.
  • a mixture of sawdust with broken firebrick in the 2:1 ratio (by weight) was subjected to gasification in an experimental laboratory reactor made of quartz.
  • a tilt angle of the reactor axis relative to the horizon was varied from 5 to 90 degrees.
  • Direct observation has revealed that with a tilt angle below 22 degrees, no filtering of gas flow through a dense fuel layer takes place because of a cavity formed along the upper generating line of the reactor, through which cavity the gas flow passes over the fuel surface.
  • burnouts form in the fuel layer along the reactor walls within a short operation time, one of the burnouts eventually extending to the feed surface. In this situation the gas product starts burning directly above the feed surface in the reactor.
