Procedure for the use of glycerine as biomass, for the production of energy by means of a spray gasification process, based on the use of a mixture of oxygen, vapour and atmospheric air as gasifying agents, which are introduced into a Gasification Chamber at temperatures above 900.degree. C., so that the gas produced is transferred to a Reformer wherein, also at temperatures above 900.degree. C., the different partial oxidation/thermal cracking reactions in the presence of metal oxides are completed and, subsequently, hot cycloned to retain ashes greater than 5 microns in size, whereupon the gas is sharply cooled using a basket-type Evaporator.
