Successfully passed the scientific and technological achievement appraisal of "Y-type entrained flow bed high-temperature zone gasification technology research and development and demonstration for solid slag discharge"! The Appraisal Committee believes that: Y-type entrained bed high-temperature zoned gasification technology has the characteristics of high carbon conversion rate, water saving, and energy saving, and is generally at the international leading level, and unanimously agreed to pass the appraisal.
Test device
1. Carried out research on the physical and chemical properties, thermal reaction mechanism, and kinetics of coal chemical family components, laying a theoretical foundation for the research and development of clean and efficient coal utilization technology.
2. For the first time, the technical route of dry slagging, ash separation, and staged heat extraction of entrained bed syngas staged cooling and separation can greatly reduce the physical water consumption of coal gasification units, and realize efficient recovery of gas-slag-ash waste heat, and cracking The common problems of high water consumption of entrained bed gasification, difficult treatment of saline wastewater and black water, and difficult utilization of gasification ash are solved.
3. Invented coal pulverized Y-type entrained bed high-temperature zoned gasification process and its equipment technology, the carbon conversion rate was >99%, the ash-slag ratio was reduced to 1:6, and the carbon content in the slag was less than 0.1%, which solved the problem of high ash in entrained-bed gasification The common problem of high ash ratio.
