Benefits of technology
The patent is about a method for gasifying a liquid substrate using solid fuels. The method has the advantage of being able to pump the mixture, reducing flammability. The separation device helps to remove any ash or solid residues that may be formed during gasification. The gasifying agent is heated to a high temperature to prevent char and tar formation and to prevent clumping of ashes. The liquid substrate is circulated through a heat exchanger before being injected into the gasifying agent, allowing for preheating. The technical effects of this invention include improved safety, reduced flammability, and improved energy efficiency.
Problems solved by technology
One of the main drawbacks which is observed in the present gasification processes is obtaining an undesired solid by-product of the gasification process, resulting from the initial pyrolysis which the part of the substrate undergoes when it is heated in an oxygen-poor environment; said by-product is called “char” and although other secondary applications may be found for said by-product, obtaining it is considered an undesired secondary effect of the gasification process.

Embodiment Construction
[0101]The present disclosure relates, as has been previously mentioned, to a system and to a method for gasifying a liquid substrate.
[0102]FIG. 1 shows a schematic view of an exemplary embodiment of the system for gasifying a liquid substrate.
[0103]According to a preferred embodiment of the system for gasifying a liquid substrate, said system comprises a gasification tank (1) connected to a tube for injecting (3) the liquid substrate.
[0104]According to a preferred embodiment of the gasification system, the gasification tank (1) comprises a vertical tubular geometry.
[0105]The tube for injecting (3) the liquid substrate comprises, at the entry thereof to the gasification tank (1), a control valve (2) of said liquid substrate.
[0106]Said control valve (2) with the injection tube (3) is designed to produce atomization or spraying in small drops of the liquid substrate into the interior of the gasification tank (1). Said atomization is produced due to the partial evaporation of the liquid...
