Definitions

  • the present invention relates to a method and a device for clean combustion and applies in particular to the burning of heavy fuels.
  • clean combustion is meant combustion without final emission of carbonaceous particles.
  • EP 7 846 a new arrangement of the elements which amounts to making, in situ, the generation of hot gases in a first zone by imposing on said gases the form of a well-vortex flow and to introduce the material to be treated into the zone in relative depression of this flow, so as to avoid subjecting the sensitive parts of the device to the prolonged action of hot gases.
  • the object of the present invention is to overcome these drawbacks.
  • the combustible substance introduced into the second zone is given a low initial speed, preferably less than 10 m / s and if possible at 5 m / s, so as not to have to increase the initial amount of movement too much.
  • hot dispersing gas phase the ratio of the momentum of said hot dispersing gas phase to that of the combustible substance being at least 100 but generally being preferably between 1,000 and 10,000.
  • the spraying thus takes place by transfer of the momentum and an isore-distributed dispersion is obtained at the entrance to the second instantaneous zone practically instantaneous in a spectrum of fine particles which are thus in the best conditions for homogeneous and rapid vaporization.
  • this spraying will be called a spraying spray.
  • this avoids the pitfall of poor dispersion of a hardly flammable substance and incomplete combustion at high temperature.
  • the present invention thus allows a spray quality which leads to clean combustion of heavy fuels, which, as already said, has not been possible until now.
  • the second gas stream is introduced tangentially to form a helical stream which can be made well-vortex by a restricted passage delimiting the second zone.
  • a material to be treated can be introduced axially into the zone in relative depression of this second flow.
  • This substance is, for example, a mineral solution or suspension, based on synthetic or natural carbonates, silicas, silico-aluminates, but it can also be of an organic nature, it can also be a. residual water to be decontaminated.
  • the first gas stream used to produce the well-vortex flow is advantageously constituted by air.
  • the first fuel introduced can be brought either in gaseous form or in the form of a spray cloud which is obtained by any known means such as a spray nozzle of the type described in the work by MASTERS (Spray Drying), or by a device of the well-vortex flow type.
  • This first fuel is preferably chosen for its ease of combustion.
  • the second fuel to be treated such as heavy fuel or combustible suspension, is introduced axially into the zone in relative depression of the well-vortex flow coming from the first zone, so as to promote the suction effect due to said zone in relative depression.
  • the second fuel is generally a fuel corresponding to types 4 to 6 of the ASTM standards.
  • the second symmetrical well-vortex flow is obtained using an oxidizing gas such as air.
  • the helical currents, introduced into a zone are advantageously under low pressure, preferably at a pressure less than 10 5 Pa relative to the pressure prevailing directly downstream of said zone when said pressure is equal to atmospheric pressure.
  • the chamber (1) has an envelope (3) closed at its upstream part by a bottom plate (4), an annular space (6) delimited internally by a perforated wall (7), a restricted passage (10), at least a pipe (8) for tangential supply of a gaseous phase and a means for injecting fuel (5) inside the chamber (1), the casing (3) ending downstream by a convergent ( 9) in which ends, along the axis of symmetry of rotation of the chamber (1), an injection device (11), substantially at the level of the restricted passage (10), the contacting chamber (2) extending downstream the chamber (1) along the same axis of rotational symmetry and being provided with a perforated wall (12) defining an annular space (13) with its envelope (14), space in which leads to at least one tangential entry (15).
  • This device can also comprise (FIG. 2) a second treatment chamber (16) of a substance introduced by a second injection device (17) disposed substantially at the level of a second restricted passage (18).
  • a hot gas is generated by combustion of a first fuel.
  • the material to be treated is introduced and the well-whirlpool effect located downstream of the restricted passage is used to disperse the fuel into very fine elements volume.
  • the cooling of the chamber 1 is ensured by a circulation of coolant comprising an annular circulation space 22 around the chamber 1.
  • This annular circulation space 22 can be replaced by a tubular assembly 23 hollowed out in the thickness of the walls of the chamber 1, as illustrated in FIG. 4, especially on a small scale.
  • the temperature of the gas phase, coming from the second zone, will largely depend on the envisaged application.
  • test 8 the gas from the system was rehomogenized in temperature in order to be able to carry out a thermal balance.
  • the temperature measured at the center of the gas outlet pipe is 850 ° C, which taking into account the experimental inaccuracies in the measurements is entirely in agreement with a temperature rise of 735 ° C for a gas that has previously been overpressed.
  • the device therefore allows the "clean" combustion of a heavy fuel (type No. 4 ASTM) with an additional fuel in the chamber (1), of the order of 1 to 10% by mass (relative to the heavy fuel )
  • This system makes it possible to generate hot gases containing little or no solid particles from the least noble fuels and it is easy to imagine the economic benefits in applications such as: drying, heating, production of steam and electricity, and in general all use of "heavy" fuels, distillation residues, combustible suspensions, etc ...
  • FIG. 5 A possible diagram of this gasification treatment is illustrated in Figure 5 where P is a device according to the invention, suitable for this type of supply (diagram in Figure 6).
  • a combustion with oxygen of a hydrocarbon Cm Hn is carried out, in the possible presence of CO 2 .
  • a solid carbonaceous material such as ground coal is introduced, either wet or put in pneumatic transport by CO 2 , or any other means.
  • zone A gasification of the solid carbonaceous material is carried out with the C0 2 introduced and the combustion gases coming from the preliminary zone P. It is optionally possible to introduce into zone A other reagents such as hydrogen for example .
  • zone B rapid quenching is carried out by a third body such as water.
  • This system makes it possible to produce a synthesis gas whose composition depends on the operating conditions of P and A.
