摘要 |
The aim of the invention is to provide a high calorific gas mixture that is obtained by gasifying biogenic solid substances and that is used for a combustion process, especially for use in conventional block-type thermal power stations. To this end, the product of gasification (31) is subjected to a treatment step (37) in which the solid portions contained in the product of gasification (31) are precipitated and in which the condensable portions of the product of gasification (31) mix with a liquid phase already present. The precipitated solid substances and the contaminated liquid phase are then subjected to a biological purification process and the purified gas (38) is used for combustion. |
