Frost control process for agriculture

Process 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， by using the cutting residues from said farms in the form of shredded material or pellets (or granules) which 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 totally ecological. The method according to the invention is intended for the protection of crops particularly in winter and spring periods. Figure for the abstract: Fig. 7
