GASIFICATION OF COMBUSTIBLE ORGANIC MATERIALS

摘要

The invention relates to a process for manufacturing a combustible gas having a calorific value below at least 1 MJ/Nm3, comprising the reaction of an oxidizing gas comprising steam or oxygen or CO2 with an organic material in contact with a molten silicate bath contained in a tank and comprising a heat input into the molten silicate, said process operating continuously, silicate being regularly discharged from the tank and batch materials being regularly introduced in order to supply the silicate bath. The heat input is preferably of the submerged combustion type. The invention also relates to a continuous industrial manufacturing process comprising a continuous production in an industrial production unit comprising a gaseous fuel burner that generates combustion gases, a continuous production of steam in a boiler, a continuous production of combustible gas in a unit for producing combustible gas comprising the reaction of an oxidizing gas comprising steam with an organic material, the combustion gases being conveyed to the boiler in order to vaporize the water and produce steam, the steam produced by the boiler being conveyed to the unit for producing combustible gas in order to react with the organic material, the combustible gas being conveyed to the industrial production unit in order to be burnt therein as a gaseous fuel.
