Abstract

The present invention describes a method for generating cold wind from slag heat wherein the method comprises the following steps: a. preparation of hot granulated slag b. preparation of wet furnace gas c. preheating of the wet furnace gas as a result of which preheated furnace gas arises d. heat transfer from the hot granulated slag to the preheated furnace gas wherein hot furnace gas arises e. expansion of the hot furnace gas in a turbine wherein energy is released and expanded furnace gas arises f. use of the released energy to drive a cold wind condenser for condensing the cold wind wherein a shaft is driven by the expansion of the hot furnace gas in a turbine wherein this shaft drives the cold wind condenser and wherein the expanded furnace gas is used for preheating the wet furnace gas as a result of which cold expanded furnace gas arises.
