Advantages of Siemens Gasification Technology

High carbon conversion efficiency of up to >99 %

Generation of a raw syngas free from hydrocarbons, i.e. absolutely tar-free

No dioxin/furan formation even at high chlorine content in the gasification feed

No heed to be given to ash content and ash composition

High gasifier performance (short retention time)

High availability

Quick gasifier startup and shutdown (approx. 1 hour)

Multiple-fuel feeding

Proven cooling screen life time >10 years
