The Use of Selected Raw Materials for Preparation Coal-Based Suspension Fuel

Abstract

Preparation of suspensions based on coal as fuels capable to replace liquid hydrocarbons is a new, intensely developed trend in the economic and technological optimization of combustion systems. The article presents results of coal-water suspensions tests. Coal from Polish mines was used for their preparation as well as other energy-bearing components as alcohol, glycol and char from rubber pyrolysis. It was developed several recipes suspension meet previously established conditions for the calorific value, rheological parameters and stability. The selected suspension was combustion a laboratory plant equipped with a burner of similar design to those used in boilers oil. Performed tests have shown the possibility of combustion the suspension, in this type of construction.
