L’invention concerne un procédé permettant d’éviter le risque de gel par une production de chaleur obtenue par la combustion de pellets (ou granulés de bois), agro-pellets ou tous autres combustibles issus de la biomasse industrielle ou agricole, de même que le combustible biomasse généré par les exploitations agricoles, viticoles arboricoles et maraichères soumises à ce risque, en utilisant les résidus de taillage desdites exploitations sous forme de broyats ou de pellets (ou granulés) qu’elles produisent chaque année. L’invention est constituée d’un système de combustion dénommé chaufferette à pellets (ou granulés) fonctionnant sans électricité et munie d’un procédé de combustion permettant une combustion par gazéification sans émanation de fumée et totalement écologique. Le procédé selon l’invention est destiné à la protection des cultures particulièrement en périodes hivernales et printanières. Figure pour l’abrégé : Fig. 7Process intended to protect crops subjected to the risk of any type of frost, and in particular that of spring called late frost. The invention relates to a method making it possible to avoid the risk of frost by producing heat obtained by the combustion of pellets (or wood pellets), agro-pellets or any other fuels derived from industrial or agricultural biomass, as well as biomass fuel generated by farms, vineyards, arboriculture and market gardens subject to this risk, using the cutting residues from said farms in the form of shredded material or pellets (or granules) that they produce each year. The invention consists of a combustion system called a pellet heater (or pellets) operating without electricity and provided with a combustion process allowing combustion by gasification without smoke emanation and completely ecological. The process according to the invention is intended for the protection of crops, particularly in winter and spring. Figure for the abstract: Fig. 7
Description
La présente invention faisant l’objet d’un dépôt de certificat d’utilité concerne un procédé destiné à être installé sur des parcelles cultivées à raison de 200 à 250 pièces à l’hectare afin de protéger les zones de culture ou d’arboriculture des risques de gel au printemps et à toute saison et en tous lieux.The present invention which is the subject of a utility certificate filing relates to a process intended to be installed on cultivated plots at the rate of 200 to 250 pieces per hectare in order to protect the cultivation or arboriculture areas from risk of frost in spring and in all seasons and in all places.
A chaque arrivée du printemps, dans les vignes, les maraîchages ou les zones d’arbres fruitiers, les gelées de printemps provoquent des ravages dans la période de montée de la sève lors du bourgeonnage, soit en avril et mai pour la zone de l’Europe de l’Ouest (Allemagne, Espagne, France, Italie, Suisse et Portugal ). Le phénomène est semblable dans les pays de l’hémisphère sud de la zone tempérée en octobre et novembre.Each time spring arrives, in the vineyards, market gardens or areas with fruit trees, spring frosts cause havoc in the period when the sap rises during budding, i.e. in April and May for the area of Western Europe (Germany, Spain, France, Italy, Switzerland and Portugal). The phenomenon is similar in the countries of the southern hemisphere of the temperate zone in October and November.
La plupart des exploitations agricoles, pour se protéger d’un évènement difficilement pris en charge par les assurances font appel à des techniques de protection. Les dispositifs existant à l’heure actuelle, forts coûteux en exploitation, sont le brassage de l’air par éolienne, l’utilisation d’hélicoptère (à l’exemple de la Champagne), l’arrosage intensif (1m3 seconde), la mise en place de bidon de paraffine en feu (400 à 500 bidons de 15 kg par hectare) et les traditionnels brûleurs à gaz et autre chaufferette au fuel. Ce sont autant de systèmes qui indépendamment de leur efficacité toute relative, ont un impact écologique néfaste pour l’environnement.Most farms, to protect themselves from an event that is difficult to cover by insurance, use protection techniques. The devices that currently exist, which are very costly to operate, are air circulation by wind turbine, the use of helicopters (as in Champagne), intensive watering (1m3 second), setting up paraffin cans on fire (400 to 500 cans of 15 kg per hectare) and traditional gas burners and other fuel heaters. These are all systems that, regardless of their relative efficiency, have a harmful ecological impact on the environment.
Le procédé ou le concept, objet du dépôt de certificat d’utilité, génère un impact carbone et environnemental positif tout en utilisant la combustion, pour produire de la chaleur protectrice. Le principe même de cette combustion, à la base du procédé, repose sur l’utilisation d’un carburant produit elles-mêmes par les plantations et les cultures à protéger. Chaque année, lors des différentes phases de taille, la récupération de bois mort génère un potentiel énergétique réutilisé dans le process sous forme de broyats ou granulés. Cependant, le procédé accepte tout type de combustible entrant dans la catégorie de l’énergie issue de la biomasse (plaquettes forestières ou industrielles, pellets, agro-pellets exemple le noyau d’olive, la coque d’amande etc…).The process or concept, object of the utility certificate filing, generates a positive carbon and environmental impact while using combustion to produce protective heat. The very principle of this combustion, the basis of the process, is based on the use of a fuel produced by the plantations and crops to be protected. Each year, during the various pruning phases, the recovery of dead wood generates an energy potential reused in the process in the form of shredded material or pellets. However, the process accepts any type of fuel falling into the category of energy from biomass (forest or industrial chips, pellets, agro-pellets, for example olive pits, almond shells, etc.).
Le principe est de produire une triple combustion par gazéification. Les fumées sont ainsi réactivées et ré-enflammées afin de générer plus de puissance, sans avoir de rejet de gaz polluant. Ce qui en résulte : une combustion totale des gaz et une fumée d’échappement quasi nulle donnant au processus une qualité de combustion presque parfaite.The principle is to produce a triple combustion by gasification. The fumes are thus reactivated and re-ignited in order to generate more power, without releasing polluting gas. The result: total combustion of the gases and almost zero exhaust smoke giving the process an almost perfect combustion quality.
En référence aux dessins (Fig1) le procédé comporte un brûleur, dont l’une des particularités est d’être munie d’une cornière située sous la ligne de combustion créant un orifice permettant ainsi le passage d’un air secondaire venant alimenter la partie intérieure du brûleur, créant de ce fait une régénération de combustion par un apport en oxygène.With reference to the drawings (Fig1) the process comprises a burner, one of the particularities of which is to be provided with an angle located under the combustion line creating an orifice thus allowing the passage of secondary air supplying the part interior of the burner, thereby creating combustion regeneration by supplying oxygen.
Les percements visibles sur l’arrière du silo de stockage du carburant, (fig. 1) permettent par l’apport d’oxygène lors de la combustion de faire chuter le taux de CO2 selon les bases du principe du système dit venturi.The openings visible on the back of the fuel storage silo (fig. 1) make it possible, through the supply of oxygen during combustion, to lower the CO2 level according to the basics of the principle of the so-called venturi system.
Selon la forme de réalisation visible sur la figure 2, des ouïes réalisées sur le tube d’échappement permettent un nouvel apport en oxygène achevant le cycle de combustion, avant la sortie même des gaz résiduels, créant ainsi une combustion optimisée sans aucune fumée.According to the embodiment visible in Figure 2, vents made on the exhaust tube allow a new supply of oxygen completing the combustion cycle, even before the exit of the residual gases, thus creating an optimized combustion without any smoke.
Il est à noter que l’invention reposant sur la gazéification de la biomasse, dès lors qu’elle emploie la technique décrite ci-dessus, autorise toute forme pour la chauffrette ou brûlot utilisé pour la lutte contre le gel, prenant alors l’aspect par exemple de bouteille de vin ou de champagne, de derrick de pétrole ou toute autre forme géométrique existante ou à concevoir.It should be noted that the invention based on the gasification of the biomass, since it uses the technique described above, authorizes any shape for the heater or firebox used for the fight against freezing, then taking the aspect for example, a bottle of wine or champagne, an oil derrick or any other existing geometric shape or one to be designed.
