Abstract

The original project encompassed shaft furnace gasification of straw, gas cleaning by means of cracking and gas washing, and gas utilization as engine fuel. Additionally experiments with wood chip gasification have been performed. In the straw gasification process a noticeable trend to combustion in the gasifier peripheric region is observed (`Ringfeuer`). Gasification of wood chips is less complicated. The porous structure of the chips provides better transfer of gas and heat, and thereby makes chemical reactions easier. Positive experience with wood chips resulted in establishment of the Voelund gasification plant at Harbooere. The conclusion of the entire project (volumes 1 - 5) is that straw is a difficult material for gasification purposes. However, the process can prove viable and competitive with a specially designed stirrer and an improved air supply, to form a fine-grained and compact pyrolytic layer. (EG)
