The briquetting of coal fines generated during coal preheating and pipeline oven charging was investigated as a possible method of handling these fines for recycling in the carbonisation process. Bench-scale briquetting tests were carried out to evaluate the process variables affecting fine coal briquetting. In general, the crushing strength of the briquettes increased with thermal ageing and increasing amounts of binder. Pilot-oven tests were carried out using various amounts of briquetted coal fines in the coking blend. The results indicated that coke stability increased slightly with the addition of briquettes composed of blended metallurgical coal. This indicates that briquetted coal fines from preheating and pipeline charging can be used as a carbonisation feed material.
