Abstract (en)
[origin: WO8602939A1] A process for dry coke cooling by means of a cooling gas in which the coke and cooling gas are fed in contra-flow through a two-stage cooling vessel, whereby the cooling in the first stage is effected at a coke temperature of about 800?oC and the cooling gas fed through the second cooling stage contains steam; the steam is produced without substantial burning away of the coke owing to the fact that the cooling in the first cooling stage is exclusively by indirect heat exchange of the coke with a cooling medium through the walls of the heat exchanger, and the cooling in the second stage is exclusively by the cooling gas which contains the steam. For this, a two-stage cooling vessel (1) is used, whose first cooling stage (1a) has jacket surfaces and incorporated cooling surfaces (8, 9) and whose second cooling stage (1b) is fed with a high steam-containing cooling gas connected with a coal-drying and pre-heating installation (4).
