METHOD OF CHEMICAL protective layer in the gasification reactor black liquor, chemical gasification reactor, the protective layer REACTOR AND METHOD FOR MANUFACTURING structural elements for such a protective layer

摘要

1. A method for organizing a ceramic protective layer in the gasification reactor intended for the processing of high energy organic waste of black liquor type with a large number of organic or inorganic metal compounds, by high temperature oxidation with air or oxygen, whereby the organic waste is converted into a hot reducing gas containing a considerable amount water vapor and the inorganic compounds form an alkaline salt melt containing at evap e 750-1150 ° C; wherein the reactor is arranged so that it consists of an outer shell (14) with its associated devices for input and output of the reactants and products; which method comprises lining the organization (16, 18) comprising one or more ceramic protective layers (16, 18) on the inside of the shell (14), such an arrangement the total thickness and the lining thermal conductivity, that the inner surface (17) of the lining ( 16, 18) facing the reaction chamber (10) has a temperature high enough to form a salt melt in contact with this surface (17) had sufficiently high bulk melt fraction to flow freely on this surface (17) and the rest of the fu temperature erovki (16, 18) which is located closer to the outer shell (14) was low enough to form a salt melt which tends, due to capillary forces or hydrostatic forces, to penetrate into the cavity in the form of joints, cracks or pores in said one or more ceramic protective layers (16, 18), solidifies to form solid salts at locations within said one or more
