PII this mvestigation, the effect of swelling pressure generated durin coal carbonixation in coke ovens on coke porosity was studied. The swe& pressure was measured using movable-wall test oven. The as pressure m the plastic layer and the swelling pressure were monitored %uring the carbonization of coals in the test coke ovens. 95/01293 Evaluation of coke quality by Mlcum, IRSID and Nlppon Steel Co. methods Dlugosx, A. ef al., Karbo-Energochem.-Ekol., 1995, 40, (5), 121, 123-125.

The authors compare three coking processes: the heat-recovery oven, formed coke making and jumbo coking reactor. The latter operates with preheated coal, program-controlled heating, and integrated pollution wntrol system, and offers good coke quality from various coal grades, a favotiable heat balance, &d greately-redu-&d emissions. -
