Briquetting may be considered good utilization technology for low grade Afsin-Elbistan lignites. For this reason, in this work, lignite samples from the Afsin-Elbistan area were briquetted with and without binder materials. The effects of moisture content of lignite samples on the briquette strength were examined without binder materials at four different briquetting pressures of 400, 550, 700 and 800 MPa. Briquetting of lignite samples without binder material gave products with low water resistance. The optimum moisture content and briquetting pressure were found to be 15% and 550 MPa, respectively. At these optimum conditions, paper mill waste, sunflower shell, sawdust and brewery waste were then used as binder materials at different ratios. Among these sawdust and paper mill waste were found to give the best quality briquettes with high calorific value and high strength. (C) 1997 Elsevier Science B.V.
