Definitions

  • the present invention relates to a closed-circuit cycle for combustion products, -" useful for fuels in any physical state (solid, liquid or gas) . It is applicable to all apparatus where combustion of solid, liquid or gaseous fuels is employed and in which the - combustion product is discharged by means of a flue, chimney or exhaust pipe and then released into the atmosphere . This method, which is universally and widely used, creates major pollution problems.
  • the combustion process normally uses the oxygen contained in the mass of atmospheric air, but in so doing it is required to heat up the whole air mass, 4/5ths of which consist of so-called inert gases; said air mass is heated increasing the amount of used fuel and is discharged in its entirety into the atmosphere, resulting in pollution due to nitrogenous substances, oxidising substances, acid water, thermal heating, etc.
  • the object of the present invention is to eliminate from the combustion process the inert substances which are contained mainly in the atmosphere, recycling only a part thereof sufficient and necessary for absorbing the thermal and kinetic energy, and then releasing it for use.
  • This object is achieved by means of a closed-circuit cycle for combustion products, to be used in internals combustion engines or plants, characterised in that the gas produced is not discharged directly into the atmosphere, but is recycled for combustion purposes.
  • the oxygen needed to meet the combustion requirement will preferably be supplied, preferably in the pure state, from a special tank which will be replenished in each case depending on the consumption required.

In this way the closed-circuit is repeatedly continuously.

  • the accumulated C0 2 may be used for industrial purposes or also alimentary purposes, avoiding the need to produce it especially, thereby limiting the increase in the greenhouse effect.
