| 摘要 |
The present invention relates to a method for cooling wood gases, wherein wood gases are formed by burning wood material in a gasifier. The wood gases formed in the gasifier (3) are cooled in a cooler (8). A boiling heat exchanger (18) is applied as the cooler (8). In the method, wood gases are cooled in the boiling heat exchanger (18) which is equipped with liquid channels (20) for cooling liquid. The amount of cooling liquid is adjusted in the liquid channels (20) of the boiling heat exchanger. The invention also relates to a device for cooling wood gases, comprising a cooler (8) to which the wood gases formed by burning of wood material in the gasifier (3) are arranged to be led, for cooling the wood gases. The cooler (8) comprises a boiling heat exchanger (18) equipped with liquid channels (20) for cooling liquid. The device for cooling wood gases further comprises means (24) for adjusting the amount of cooling liquid in the liquid channels (20) of the boiling heat exchanger. The invention also relates to a wood gas generator (1) comprising a gasifier (3), a device (8) for cooling wood gases, and a combustion engine (3). |
