Method and tank for producing hot briquettes

Patent ·
OSTI ID:6209848
; ; ; ;
A method for producing hot briquettes, for example, for use in blast furnaces, and using a briquetting material of non-caking components, such as low temperature coke from bituminous coal and/or lignite, coke dust and/or oil coke and caking fat coal at temperatures between 430* C. And 540* C. is described. The briquetting material is delivered to a briquetting press to form briquette blanks, tempering and degassing the blanks, by delivering the blanks into individual chambers in a closed system of several chambers having gas communication with each other so that there is partly changing amounts of gas generated in the individual chambers. The briquette blanks are formed into tempered briquettes. An overpressure is applied to the chambers to conduct the gases away from the chamber with one and the same overpressure. The equipment for the execution of the method comprises a hardening system in the form of a single cube-shaped tank having one corner which is inclined downwardly and which is divided into several substantially parallel narrow chambers by walls which are disposed parallel to the inclined outer surface and which has a channel above an upper lateral edge for charging hot briquettes into the individual chambers and also for conducting away gases formed during tempering in a path diagonally opposite to the charging channel. An emptying channel is located under the lower lateral edge of the tank.
