| 摘要 |
The invention relates to a heat treatment process for a material in an oven (4), such process using the combustion gases supplied by at least one burner (5) associated with a firebox (6). This process is characterised in that a first condensation phase is provided for the combustion gases between their exiting the firebox (6) and entering the oven (4), such condensation enabling part of the dust contained in the combustion gases to be eliminated, the first condensation phase being conducted using absorption refrigerating means (14) followed by a superheating phase of the combustion gas allowing the required temperature to be obtained for the heat treatment. The invention also relates to a treatment unit implementing such process. The process is more particularly applicable to the heat treatment of wood.
