3.2 High Temperature Gasification
High temperature gasification is normally operated at temperatures above 1200 ̊C. The main reactor type is the entrained flow gasifier (EF) [15]. At these high temperatures the feed is completely converted into product gas, even at the short residence time of only a few seconds. There are two different types of EF:
Slagging, where the ash is molten
Non slagging, where the ash remains solid.
