Operation analysis and optimization of dry pulverized coal gasification quenching process
The process flow of the dry pulverized coal gasification quenching process for the 4 million t/a coal indirect liquefaction project of China Energy Group Ningxia Coal Industry Co.,Ltd.was introduced.In response to the problems of syngas carrying water,slag and ash during the operation of the gasifier quenching process system,the analysis showed that the main reasons were improper liquid level control of the quenching chamber,poor washing water quality of the syngas scrubber tray and unreasonable design of the tray structure.For these reasons,corresponding technical improvements and optimizations were carried out in terms of structure,materials,pipelines and other aspects.The operational results showed that the problems of water,slag and ash carriage in the syngas had been effectively solved after the transformation,and the pressure difference of the syngas scrubber tray tended to stabilize.
