Definitions

  • the present invention relates to a solid fuel gasification and/or combustion system intended to equip a gasification and/or combustion installation.
  • the present invention also relates to a gasification and/or combustion installation provided with such a gasification and/or combustion system.
  • the present invention also relates to a method of implementing such a gasification and/or combustion installation.
  • a gasification and/or combustion installation comprises a hearth inside which a bed of a solid fuel, in particular from biomass, is burned to provide heat. Such an installation also generates mineral residues, such as ashes or the like.
  • a general problem posed in this area lies in the continuous evacuation of mineral residues produced during the combustion and/or gasification of solid fuel. Indeed, it is desirable to avoid regular shutdowns of the gasification and/or combustion installation to occasionally evacuate mineral residues. Also, it is known to equip the gasification and/or combustion installation with an ash removal grid which is designed to evacuate mineral residues from the hearth.
  • US 4,388,876 A shows a combustion system with a supply pipe in the center of a rotating grate. The two-part form of claim 1 is based on US 4,388,876 A .
  • the gasification and/or combustion installation must allow the solid fuel to be set in motion to continuously supply said installation as the fuel is burned and/or gasified.
  • the gasification and/or combustion installation must also allow the evacuation of mineral residues as they are produced, such evacuation must be carried out at a controlled speed. Indeed, a speed of evacuation of mineral residues that is too rapid risks inducing evacuation of unburned solid fuels, which negatively affects the efficiency of the gasification and/or combustion installation. Conversely, a speed of evacuation of mineral residues that is too slow risks inducing the formation of clinker which is likely to damage said installation.
  • the gasification and/or combustion installation must in all circumstances avoid the production of clinker which results from a melting of mineral residues when a hearth temperature is higher than a melting temperature of the mineral residues.
  • the gasification and/or combustion installation must be provided with an air injection device to supply the hearth with an appropriate quantity of air which is notably necessary for the complete combustion of a tank, coming from a incomplete combustion of solid fuel.
  • air injection must also be carried out appropriately to guarantee a rise in temperature of the solid fuel allowing drying, pyrolysis and combustion of the solid fuel.
  • the gasification and/or combustion installation must allow control of the height of solid fuel inside the hearth.
  • the height of solid fuel inside the hearth affects the combustion and/or gasification conditions and is likely to cause malfunctions in said installation.
  • a height of solid fuel is too great, due to a change in fuel characteristics or a variation in operating conditions, this results in an increase in pressure loss within the solid fuel bed. , which is detrimental.
  • An excessive height of solid fuel inside the hearth is likely to affect the injection of air into the hearth, or even to block such injection, and ultimately to cause said installation to stop.
  • the gasification and/or combustion installation must be compatible with a variety of solid fuels. Indeed, it is desirable to be able to consume and/or gasify solid fuels having variable properties, such as a humidity level, a calorific value, an ash level or the like, inside the hearth. This results in a need to equip the gasification and/or combustion installation with a regulation system allowing the transition from a solid fuel to another solid fuel, without having to shut down said installation.
  • the gasification and/or combustion installation must be airtight, particularly at its hearth, to avoid in particular the entry of parasitic air, gas leaks and/or thermal losses.
  • An aim of the present invention is to propose a system for the gasification and/or combustion of a solid fuel intended to equip an installation for the gasification and/or combustion of a solid fuel, in particular from biomass, which meets the requirements of all of the above objectives.
  • Another aim of the present invention is to propose an installation for gasification and/or combustion of solid fuel which meets all of the above-mentioned objectives.
  • Another aim of the present invention is to propose a method of implementing such an installation which offers a better compromise between the aforementioned objectives.
  • the present invention improves the situation, by proposing a system for gasification and/or combustion of a solid fuel intended to equip a reactor with an installation for gasification and/or combustion of a solid fuel, in particular from biomass, which comprises an ash removal grid overhung by a cone for supplying solid fuel to the reactor from below, the ash removal grid being automated, cooled and actuated by a piston, the gasification system and/or combustion offering the best compromise between the aforementioned objectives. More particularly, such a system allows a thermal combustion reaction of good quality while limiting the formation of bottom ash, in particular by allowing evacuation of mineral residues, ashes in particular, continuously, the gasification and/or combustion system making it possible to burn successively distinct solid fuels, without stopping said installation.
  • the present invention also relates to a gasification and/or combustion installation comprising such a gasification and/or combustion system, the gasification and/or combustion installation comprising a reactor delimited by at least one wall which houses the gasification and/or combustion system,
