Abstract

In gasifying coal in a preferably allothermally heated gas generator, the hot product gas taken off from the gas generator is used as the heating medium for generating high-pressure and/or low-pressure steam, and the condensate water obtained from the product gas on cooling is separated off, freed of any volatile or organic impurities present therein and then evaporated in an evaporator and returned as process steam into the gas generator. The high-pressure and/or low-pressure steam is used as the heating medium for the evaporator, if appropriate after previous utilisation in a steam turbine. This leads to environmentally friendly recycling of the condensate water from the product gas.
