Atmospheric pressure oxygen-enriched circulating fluidized bed high alkali coal gasification to synthesis gas technology passed the appraisal

On September 4th, the "Atmospheric Pressure Oxygen-enriched Circulating Fluidized Bed High Alkali Coal Gasification to Syngas Technology" jointly completed by the Institute of Engineering Thermophysics of the Chinese Academy of Sciences, Xinjiang Yihua Chemical Co.

Participating experts said that the Xinjiang Zhuandong Coalfield is currently the largest coalfield in China, with a predicted reserve of 390 billion tons

According to Zhu Zhiping, director of the Circulating Fluidized Bed Laboratory of the Institute of Engineering Thermophysics of the Chinese Academy of Sciences, the high-alkali coal in the Zhuandong region of Xinjiang has the characteristics of poor viscosity and temperature characteristics, poor slurrability and high alkali metal content, and the gasification technology of the gasification of the gas flow bed is difficult to apply

Zhu Zhiping introduced that the atmospheric pressure oxygen-enriched circulating fluidized bed high-alkali coal gasification to synthesis gas technology developed by them, taking Xinjiang Zhuandong coal as the research object, through the technological innovation of temperature partition control in the furnace, flow field and reaction regulation, temperature zone matching control of waste heat recovery system and gas sealing dry slag discharge of slag discharge pipes, etc.

According to Yang Xiaoqin, chief engineer of Xinjiang Yihua Chemical Co.

The device has passed the 72-hour continuous operation site assessment
