PURPOSE: To prepare a solid formed fuel similar to charcoal and free from problems of emitting smoke and ill odor, by kneading crushed petroleum coke, charcoal powder, and a binder at specific ratios, and forming and calcining the mixture to remove the volatile components.
CONSTITUTION: 80W50pts.wt. of A petroleum coke powder crushed to ≥14 mesh, pref. ≥60 mesh, is mixed with 20W50pts.wt. of charcoal powder (carbonized and powdered bark, wood chips, sawdust, etc.) to obtain 100pts.wt. of the mixture, which is mixed with 2.5W10pts.wt of a binder and formed. The formed product is carbonized in an inert or weakly oxidative atmosphere at 500W800°C for 3W60min to remove almost all water content and about 10W50% of the volatile components which vaporize at ≤500°C and obtain the objective solid fuel.
EFFECT: The fuel thus obtained has excellent ignitability, high calorific value, little residual ash after combustion, and longer combustion time than charcoal.
