METHOD AND APPARATUS TO EXTRACT PRODUCTS FROM HEAT TREATMENT PROCESS

The present invention relates to a method for treating a vent gas steam from heat treatment of plant biomass. The invention also relates to an apparatus for performing the method for treating a vent gas steam from heat treatment of plant biomass. 1. A method of treating a vent gas steam from heat treatment of plant biomass , comprising the steps of:heat treating plant biomass in a heat treatment chamber,directing the vent gas steam from the heat treatment to a series of condensers connected to each other to provide flow of the vent gas steam through the entire series,collecting at least part of the components of the vent gas steam in each condenser,wherein each of the condensers is set at a temperature that is lower than the temperature in the previous condenser in the series, andwherein the first condenser in the series is set at a temperature that is lower than the temperature in the heat treatment chamberwherein the series of condensers comprises at least two condensers is set at a temperature of above 100° C. and at least one condenser set at a temperature of below 100° C., andwherein the heat treatment of plant biomass is performed at a temperature of 160° C. to 300° C.2. The method as claimed in claim 1 , wherein the series of condensers comprises three or more condensers.3. The method as claimed in claim 1 , wherein a shielding gas claim 1 , preferably steam claim 1 , is used in the heat treatment.4. The method as claimed in claim 1 , wherein the first condenser in the series of condensers is set at a temperature of above 100° C. and the next condenser(s) in the series is (are) set at a temperature of below 100° C.5. The method as claimed in claim 1 , wherein the condenser series comprises condenser(s) set at a temperature above 130° C. claim 1 , condenser(s) set at a temperature of above 100° C. to 120° C. and condenser(s) set at a temperature of below 100° C.6. The method as claimed in claim 1 , wherein the plant biomass is wood.7. The method as claimed in ...

Arrangement and method for attaching a device into a planar surface structure

The object of the invention is an arrangement and a method for fastening a device onto a planar surface structure, such as onto a wall. The invention is most preferably applicable for the fastening of a drying rack which is to be heated by electricity or by circulating water. In the solution according to the invention, an inner portion is used which is fastened on one hand onto a wall and on the other hand onto a fastening support of the drying rack. The drying rack with its inner portions is placed for a moment at a desired mounting spot, in which case the inner portions become attached and remain at their proper places by adhesive attachment. The inner portions can thereafter be fastened with screws onto the wall without the drying rack or a stencil. Finally, the drying rack is set at its place and fastened to the inner portions, in which case the screws which have been fastened into the wall get covered and are protected from splash water.
