A method for heat treating a pulverized solid fuel, comprising drying said fuel, subjecting it to pyrolysis in two stages with the subsequent formation of steam, gaseous products and small coke, effecting additional heating of at least some amount of said small coke, at a temperature comprised between 800 and 1500º c, by means of combustión gas and/or partially burning the small coke, separating the small heated coke from the charged combustión gas in the first pyrolysis stage and destined to dry said fuel, gasifying the small heated coke by steam with the resulting separation of the small coke from the gasification products, and collecting the coke often for later use as a heat carrier in the first stage of pyrolysis.
