As a result of industrial test investigations on the coking of partially compacted charges by the method of briquetting without a binder it was shown that: (1) It is possible in practice to briquette coal charges without a binder to obtain small briquettes weighing about 7-8 g, with density of 1.14 to 1.15 g/cm/sup 3/, sufficiently strong that these briquettes may be used as a component of a coal charge loaded into coke ovens. (2) There ia an increase in the mechanical strength of the coke by the M40 index by 3% and a decrease in the M10 by 1.2% in the box coking of partially compacted industrial coal charge of the Moscow Coke Gas Plant. (3) There is an increase in the yield of the over 40 mm size class coke (by 5 to 10%) with a corresponding decrease in the yield of the finer size classes) depending on the caking capacity in the box coking of partially compacted charges. (4) It is possible to increase (with partial compaction of the charges) the proportion of Kuznetsk poorly-caking coal in the industrial charge of the Moscow Coke Gas Plant to 50 to 60% in comparison to the present 20%.
