Abstract Developments on entrained‐flow gasification using the Koppers‐Totzek and the Prenflo process . Many years of operating experience have permitted continuous improvements in capacity and availability of entrained‐flow gasification plant applying the Koppers‐Totzek process. Further increases in capacity and economy, in particular where poorly reactive coals are to be gasified, will be achieved using the pressurized Prenflo process. Gasifier development is being supplemented by the development of complementary equipment, such as dry coal‐dust feed, material flow metering, and process automation. Closed wash water systems and other processing stages serve to improve environmental protection. The combination of pressurized gasification with a power station permits economical power generation with a high degree of efficiency and minimal environmental impact. Individual problems connected with pressurized gasification are being researched in a 48 t/d pilot plant.
