A process for the wet carbonizing of peat, wherein the peat is diluted and screened to become a raw peat suspension in a suspension preparing apparatus, the peat suspension thus obtained is preheated in series-connected heat exchangers and in a preheating tower, the preheated suspension is wet carbonized in a reactor into which steam is introduced from a steam boiler, the wet carbonized peat suspension is cooled in the preheating tower, mechanically dewatered in a dewatering apparatus and dried in a drying apparatus with the aid of hot drying gas, the exhaust gases from the boiler being employed as drying gas in the drying apparatus and the dust and water vapor containing exhaust gas emerging from the drying apparatus being purified and cooled in a wet separator, wherein part of the water vapor in the exhaust gas condenses and wherein there is used as washing water, polluted water coming from the dewatering apparatus and being cooled by heat exchange with the raw peat suspension in the heat exchanger, and the dust-laden and heated drain water from the wet separator being used as dilution water in the suspension preparing apparatus.
