[en] Automatic translation: The semi-technical plant was in operation for over 2600 hours in the first half of the year, 2000 hours of which in hot operation and 1500 hours in gasification operation, with 315 t of coal being put through. In the months of May to June she worked practically without interruptions. The 1978 measured Relationships between residence time and degree of gasification were found Anthracite confirmed, with values ​​of over 90% for the latter revealed. By increasing the heat supply, the gasification output could be increased to 183 kg C / h, corresponding to approx. 200 kg feed coal / h. In a pilot plant of the BF, after the LR process from a baking gas flame coal (Westerholt) 20 t of low-temperature coke produced at 580 ° C and in the semi-technical Plant gassed without difficulty. He behaved similarly to that Anthracite. This means that the pre-degassing can be used as a Experimental alternative solution for the gasification of baking coals secured. The preparations for the direct entry of baking hard coals planned for autumn 1979 by means of blasting are currently being carried out. performed. In detail, the following can be said about the work: The investigations on heat transfer and reaction kinetics in Gas generator of the semi-technical coal gasification plant are in second quarter 1979 continued as planned. As planned, the test facility was taken out of operation on June 22nd, 1979 for expansion measures. Fig. 1 gives an overview of the timing of the trial operation. A roughly three-week renovation of the system (re-equipping the electric steam superheater with heating cartridges and Change of the coal downpipe) followed a 36-day almost uninterrupted gasification operation from May 14th. - June 19, 1979. The three Short interruptions - one day each - come about when the electric helium heater is shut down as a precautionary measure to inspect and supplement the heating conductor (pitch coke pouring) has been.
