Entrained-flow gasifier for Vacuum residue from refineries

摘要

The present invention relates to a wet-classification of the heavy residue gasification unit, and its object is to ensure the flow through the pre-heating to a solid smooth supply of the heavy residue in the final product of high sulfur and room temperature in the refiner and convenient transport of the fuel and that, to facilitate the combustion control, there is provided a wet classification, gasification apparatus using the heavy residue to filter the air pollution gas such as sulfur generated by combustion inevitably.; The configuration of the present invention is the slurry burner, comprising a combustion and reaction of the central gasification reactor, in the wet-gasifier made twos of the lower gas and slag cooling, and then heating the heavy residue of the solid to which the device on the liquid gasifier shear Steam after injection with the fluidizing and preheating means for supplying fuel of high temperature and high pressure and superheated (superheating); It characterized in that buffer by pressure variations inside the gasification reactor, cooling bath of a liquid gasifying apparatus constructed in order to maintain constant the surface of the cooling water inside the cooling tank includes a gas guide tube attachment by double tube type.
