Abstract
The invention relates to a method for utilizing the heat energy of domestic and commercial refuse in a rotary kiln installation. The prepared crude refuse is degassed in a pyrolysis reactor and the pyrolysis gas produced is delivered to the main burner of the rotary kiln, optionally using primary fuel. For optimum and economic production of the pyrolysis gas crushed refuse is dried pneumatically with the aid of exhaust air from the cooler and is delivered to the pyrolysis reactor. The pyrolysis reactor is heated indirectly to a low temperature with hot secondary air from the kiln outlet head and the pyrolysis gas produced is delivered together with used secondary air to the main burner of the kiln.
