ABSTRACT:
Stalks of crop material, especially straw, are incinerated by comminuting them to pieces having a length of substantially 8 to 10 cm, pneumatically transporting the stalks to a separator in which the air is separated from the stalks and the stalks are then compacted and advanced in a rising bed into a furnace. Within the furnace, a low temperature distillation is initially effected and combustion is promoted along the free surface of the bed, in part sustained by the gases produced by the distillation. Ash as it is formed on the surface is entrained away with the hot gases. The ash is separated from the hot gases and advantageously collected in a water basin while the hot gases can be used for agricultural drying purposes and the ash for fertilizer.
