Definitions

  • This invention concerns a gas generator to produce methane gas and carbon oxide.
  • the invention is used to produce methane gas and carbon oxide with a reduced content of free hydrogen and nitrogen starting from selected solid refuse, both domestic and/or industrial, or from low-cost solid products such as wood chips and wood discards, solid biomasses in general, peat, lignite, carbon fossils and other comparable products.
  • the state of the art includes various types of gassification devices to produce, from various types of waste materials or from low-cost raw material, combustible gases which are used to feed user machines of various types, such as for example the motors of generator sets for the production of electric energy or heating boilers.
  • Gas generators such as are employed at present, however, - an example of which is described in EP-A-001.856 and EP-A-001.857 - are able to produce methane gas and carbon oxide characterised by a high content of free hydrogen and nitrogen.
  • gassification device also called gas generator
  • problems encountered in the various stages of the gassification process are because of problems linked directly to the gassification device, also called gas generator, and also because of problems encountered in the various stages of the gassification process.
  • EP-A-001.856 and EP-A-001.857 describe plants to produce combustible gas and water gas starting from solid and liquid fuel.
  • the presence of water gas is disadvantageous since it is not easily adaptable for subsequent use in Diesel motors and Otto motors.
  • the present Applicant has designed and embodied this invention to overcome the shortcomings of the state of the art and to obtain further advantages.
  • the purpose of the invention is to provide a high performance gas generator able to produce methane gas (CH 4 ) and carbon oxide (CO) with a high calorific power, with a minimal production of water gas H 2 , starting from solid fuel.
  • CH 4 methane gas
  • CO carbon oxide
  • Another purpose of the invention is to provide a gas generator able to carry out a controlled recovery of heat, both inside and outside the gas generator itself, so as to be able to improve the gassification process in terms of yield and efficiency of the reactions, also exploiting the contribution of heat which is normally dispersed, such as that coming from the exhaust fumes of the user machines and from the cooling of their mechanical parts.
  • a further purpose is to optimize the yield of the chemical reactions inside the gas generator, by using sheets in the area of the hearth which are surface-treated with catalyzing material to encourage the formation of methane and to reduce to a minimum the presence of free hydrogen.
  • One characteristic of the invention is that it has a structure able to carry out energy recovery, both inside and outside the gas generator, so as to produce a considerable quantity of super-heated steam which is divided into hydrogen and oxygen; these are used both as a contribution of combustible gas for the production of methane, and also a comburent gas to replace part of the air taken into the gas generator from outside.
  • the gas generator according to the invention therefore, is able to produce a combustible gas with an improved calorific power, yet still uses a lesser quality of solid fuel compared with conventional gas generators.
  • the gas generator according to the invention provides a maximum exploitation of energies which otherwise would be lost, such as the heat possessed by the gas produced, the cooling heat of the mechanical parts of the user machines, the heat of the exhaust gases of the machines and suchlike.
  • the heat recovered by the gas generator according to the invention from cooling the mechanical parts of the user machines and from the heat of the exhaust gases from the user machines, is used, together or separately, to fulfil at least one of the following functions:
  • the heat recovery is achieved, using conventional techniques, by means of recovery chambers provided for the purpose.
  • first recovery chamber in which at least part of the heat possessed by the exhaust gases of the user machine is recovered, and/or from the cooling of the mechanical parts of the user machine, and at least a second recovery chamber in which at least part of the heat possessed by the combustible gas produced is recovered.
  • the solid fuel Before being introduced into the gas generator, the solid fuel is optionally subjected to a dehydration process, in order to reduce to a minimum the absorption of heat energy by the gas generator.
  • the dehydration process is carried out by exploiting the residual heat of the exhaust gases of the user machines, for example a motor, and/or the heat of the cooling water of said machines.
  • the fuel in the upper part of the gas generator, is subjected to a dry distillation reaction, that is to say, without combustion, of at least a percentage of the volatile parts of the fuel.
  • the solid fuel reaches the lower part of the gas generator already heated and without its volatile parts so that gassification occurs in a shorter time, without unburnt distillates, and with less energy required.
  • the distillation reaction is achieved by means of heating the solid fuel obtained by making the exhaust fumes of the machines circulate in the afore-said first recovery chamber defined by suitable interspaces made in the upper part of the gas generator.
  • the upper part of the gas generator is connected with a heat exchanger able to condense a defined quantity of the volatile parts to produce liquid fuel.
  • Any quantity of the volatile part which cannot be condensed is sent into the lower part of the gas generator to feed separately the oxidizing combustion and therefore the process of dividing the super-heated steam, which is fed parallel to the lower part, into oxygen and hydrogen.
  • the oxygen produced by the fission process reproduces itself and feeds the combustion without needing any other comburent to be added according to the quantity of gas required by the user machine.
  • the gas generator according to the invention is therefore able to regulate itself according to the variations in the requirement of combustible gas and in the production of exhaust gases by the user machine.
  • the reduction in quantity of air taken in from the outside entails a drastic reduction in the supply of nitrogen.
  • nitrogen passively occupies a considerable volume in the fluids circulating in the hearth of the gas generator, it absorbs heat passively and considerably reduces the calorific power per unit of measurement of the gas produced.
  • the oxygen derived from the fission of the super-heated steam is usually in excess and, for this reason, the gas generator according to the invention has a conformation such that a part of the carbon produced by the solid fuel also reaches the last interspace in which the gas produced passes before it emerges from the gas generator to be delivered to the user machine.
  • gassification is encouraged by the fact that the fluids moving in the gas generator can follow ascending or descending paths and also horizontal paths, according to the variable resistances which they may meet among the fuel.
  • the said paths of the fluids inside the gas generator are defined by separating walls able to define apertures of preferential passage.
  • the paths of the fluids in the upper part destined to dry distillation are encouraged by the presence of ventilation means, whereas in the lower zone relating to the formation of gas, they are caused by the forced intake towards the user machines.
  • At least the walls arranged in the zone of the gas generator affected by the reducing combustion are made of nickel alloys or are treated with nickel.
  • Nickel exercises a catalyzing action on the carbon and free hydrogen produced by the reducing combustion, encouraging the formation of methane gas and the production of a quantity of oxygen, with the advantage that less comburent air is required from outside the gas generator.
  • the gas generator can carry out an alternative function to produce charcoal.
  • This alternative function is obtained by connecting, on the outside, the lower inlet of the gas generator with the gas outlet mouth and making the gases present between the mass of fuel re-circulate, after they have been cooled in a cooling device, inside the heap of coal which lies in the lower part of the gas generator.
  • the burner will continue to remove the distilled substances from the upper part, modulating their removal thermostatically according to the most suitable temperature, normally between 270°C and 320°C.
  • the gas generator 10 includes a containing structure on a vertical axis, substantially cylindrical in shape and equipped with suitable insulating linings at least on the outer peripheral surface.
  • the gas generator 10 comprises two principal parts, an upper part 10a, in which a dry distillation, that is to say, without combustion, of the volatile parts of the solid fuel occurs, and a lower part 10b in which combustion and the formation of the gas takes place.
  • the upper part 10a is equipped with an inlet aperture 11 with which a loading device 12, of the gas-tight type, is coupled; the loading device 12 is used to load the solid fuel, which may include wood and biomasses in general, including solid domestic waste from differentiated rubbish collections.
  • the loading device 12 is of the Archimedean screw type and is governed by a level probe 13, which ensures there is a continuous presence of a defined quantity of solid fuel inside the gas generator 10.
  • the loading device 12 is of the type with a star valve.
  • the upper part 10a is equipped at the center with a vertical conduit 15 surrounded by coaxial containing walls which define, proceeding from the outside of the gas generator 10 towards the inside, an outer upper annular interspace 16, an intermediate upper annular interspace 17 and an inner upper annular interspace 18.
  • the solid fuel loaded into the upper part 10a is positioned in the inner annular interspace 18 and begins to heat up due to the effect of the hot gassy fluids which, at least in the initial cold start step, for some minutes, rise from the lower part 10b of the gas generator 10.
  • the hot gassy fluids are heated by the exhaust gases of the motors of the user machines, introduced into the gas generator 10 through an aperture 19 which sends them inside finned tubes, inner 53 and outer 56, arranged in a ring so as to delimit said interspaces 16 and 17.
  • the hot fumes are then made to circulate through the outer annular interspace 16 by at least a centrifugal fan 14 (advantageously there are two fans 14 arranged diametrically opposite) located in the high part of the gas generator 10 and forced, through the solid fuel, inside the central conduit 15 to be then put back into circulation together with fresh gassy fluids evaporated from the fuels during the dry distillation.
  • a centrifugal fan 14 advantageousously there are two fans 14 arranged diametrically opposite
  • the passage of the gassy fluids from the annular interspace 17 both towards the annular interspace 18, and also towards the central conduit 15, is made possible by the fact that the conduit 15 is defined by a plurality of truncated-cone rings 22, superimposed and distanced from each other, and also by the fact that the annular interspaces 17 and 18 share a cylindrical wall 23 defined by a plurality of truncated-cone rings 23a superimposed and distanced from each other.
  • the gassy fluids are super-heated by the exhaust gases or fumes produced by the user machine, such as a boiler, a motor or suchlike, and introduced into a first recovery chamber 54 associated with said inlet aperture 19.
  • the first recovery chamber 54 is connected to a second, upper recovery chamber 55, by means of said finned tubes 53 and 56; after having yielded their heat to the fuel and contributed to its dry distillation in the upper part 10a of the gas generator 10, the exhaust gases are discharged by means of an outlet mouth 20.
  • the outer interspace 16 is laterally delimited by the series of outer finned tubes 56 and by the series of inner finned tubes 53
  • the intermediate interspace 17 is laterally delimited by the same series of inner finned tubes 53 and by the cylindrical wall 23 with the truncated-cone rings 23a.
  • the upper part 10a is also equipped with an outlet 24 connected by means of a conduit 25 equipped with an intake aperture 25a to the inlet 26a of a heat exchanger 26.
  • These condensed fuels can be used, for example, as liquid fuel to light the gas in the case of user machines consisting of Diesel motors.
  • the heat exchanger 26 is also equipped with an outlet 26b, through which that part of the distillates which is not condensed is discharged.
  • the outlet 26b is connected, by means of a conduit 28 equipped with a non-return valve 45, to the lower part 10b of the gas generator 10, to be more exact, in correspondence with the hearth 30, in order to re-introduce inside the gas generator 10 the non-condensed volatile parts of the biomasses.
  • conduit 29 equipped with a valve 46, to return said non-condensed volatile parts to a burner 31, with which the volatile parts are burnt and used, by passing inside the finned tubes 53 and 56, to contribute to the dry distillation of the woody biomasses in the upper part 10a of the gas generator 10.
  • the lower part 10b is equipped with an inlet conduit 32 through which comburent air is taken in, according to the requirements of the user machine, from the outside and sent to the hearth 30.
  • the lower part 10b is also equipped centrally with a conduit 21, axial to the conduit 15, through which the products of the first combustion occurring in the hearth 30 arrive from said hearth 30.
  • the hearth 30 is advantageously governed by a regulation thermostat 58b to maintain the temperature at values of around 700+800 °C, possibly discharging any excess steam generated through a discharge outlet.
  • the conduit 21, like the conduit 15, is defined by a plurality of truncated-cone rings 43 superimposed and distanced from each other.
  • fins 40a, 43a, 44a Coaxial to and outside around the conduit 21 there are fins 40a, 43a, 44a which form vertical containing walls able to encourage the development of the catalyzing reaction of the nickel with which they are lined.
  • first annular interspace 33 Proceeding from the outside of the lower part 10b of the gas generator 10 towards the inside, there is a first annular interspace 33, a second annular interspace 34, a third annular interspace 35, a fourth annular interspace 36, a fifth annular interspace 37, a sixth annular interspace 38 and a seventh annular interspace 39.
  • the flames of the hearth 30 develop; they extend as far as the sixth annular interspace 38 where the solid fuel progressively descends.
  • the passage of the flames from the interspace 39 to the interspace 38 is made possible by the fact that the wall 40 shared by said interspaces 38 and 39 is defined by a plurality of truncated-cone rings 40a superimposed and distanced from each other.
  • the interspaces 37 and 38 are inter-communicating since the wall 44 which divides them consists of truncated-cone rings 44a superimposed and distanced from each other.
  • the solid fuel is progressively burnt in the interspace 38 and transformed into ash.
  • the ash is discharged from the gas generator 10 by means of an extraction device 41, in this case of the endless screw type, which is activated automatically on a thermostatic command 57 according to the temperature of the ashes.
  • the gas produced rises through the interspace 37 and reaches an outlet mouth 48, provided with a valve 49, connected to the user machine.
  • the outlet mouth 48 is connected by means of a conduit 50 equipped with a valve 52 to the inlet of a cooling device 51, used exclusively during the alternative use of the gas generator 10 as a device to produce charcoal.
  • the steam produced finds the right conditions to start dividing into hydrogen and oxygen.
  • the oxygen produced, proceeding along the whole extension of the hearth 30, is able to reproduce itself and feed combustion without requiring any other comburent according to the quantity of gas required by the user machine.
  • the metal parts inside the gas generator 10, and in particular the truncated-cone rings 40a, 43a and 44a defining the walls 40, 43 and 44, and also the walls of the interspace 37, are treated and/or made with a catalyzing material, for example nickel, which acts as a catalyzer in the combination of the carbon with the oxygen, thus encouraging the production of methane gas.
  • a catalyzing material for example nickel
  • the particular arrangement of the series of truncated-cone rings 44a of the wall 44 allows a part of the carbon in the interspace 38 to pass into the interspace 37.
  • the gas generator 10 as described heretofore functions as follows:
  • the methane gas likewise starts to form through the annular interspaces 37, 38 and 39.
  • interspace 37 is also made of sheet treated with nickel, the formation of methane gas is further encouraged, reducing any possible excess of free hydrogen. Even if this might cause a further production of carbon dioxide, it is in any case advantageous since it gives greater guarantees of having, at outlet from the gas generator 10, a combustible gas with a high calorific power which is safer to use in high compression motors, particularly Diesel motors, in which the free hydrogen might cause unwanted self-ignition.
  • the gas generator 10 When the need to produce gas is over, or in other dead times, the gas generator 10 according to the invention can be used to produce charcoal, continuously and simply, without combustion in the lower part 10b.
  • the production of charcoal can also be carried out for the first load of fuel in new gas generators, or of old generators which have to be re-loaded, so that it is possible to carry out extraordinary maintenance work inside.
  • a thermostat 58a can regulate the working temperature so as to obtain the total distillation of the volatile parts, for example for temperatures of 270+300 °C, or partial distillation, with temperatures of about 240+250 °C, so as to obtain condensates without tar or other impurities.
  • the thermostat 58a can condition the activation of an appropriate valve (not shown here) which regulates the delivery of part of the burnt distillates to be used for the prior dehydration of the fuel; the other part of the distillates enters through the chambers 54 and 55, exchanging heat with the finned tubes 53 and 56 and then exiting through the aperture 20.
  • the woody biomasses previously dehydrated, find themselves in an environment 15, 18 at a temperature that facilitates the evaporation of the volatile parts, which as they evaporate increase in volume and exit through the aperture 25a to be sent either to the heat exchanger 26 or again inside the gas generator 10.
  • the woody biomasses descend along the conduit 15, freeing themselves from the volatile parts and transforming into carbon, since they are subjected to a re-circling of the volatile parts generated by the fans 14, which make the volatile parts pass between the finned tubes 53 and 56, causing them to be super-heated thanks to the action of the burner 31.
  • the dehydrated biomasses arrive in the lower part 10b of the gas generator 10, in which they are simply cooled by the re-circling of gassy fluids.
  • the gases produced are made to recirculate in the gas generator 10, by means of the fan 59, after they have been cooled in the cooling device 51, inside the heap of coal which lies in the lower part 10b.
  • the dry distillation and pre-heating process of the solid fuels in the upper part 10a of the gas generator 10 is performed by the burner 31 which continues to take the distilled substances from the upper part 10a, modulating the removal thereof thermostatically according to the most suitable temperature, normally between 270°C and 320°C.
