Abstract:

 The development and application situation of SCOPE 21 coke-making technology was introduced, through the comparison and analysis on development and application, the difference existing between the expected case and applied case of SCOPE 21 can be seen. The difference between SCOPE 21 commercial device and single oven test device showed that hot briquetting temperature was reduced from 350~400℃ to 165℃; the temperature of coal charged into oven was reduced from 350~400℃ to 250℃;  coke cake temperature was increased from 750~850℃ to 1 000℃; the coking time was extended from 7.4h to 13h. As viewed from actual operation condition, there was a certain difference between practicable effect SCOPE 21 commercial device and expected effect of single oven test device.
