Abstract

The invention relates to a method for the purification of the process gas in a soldering furnace, which influences said gas on the path from the withdrawal points (31) in the soldering furnace (11) to a condensation trap (28), with regard to the temperature and volumetric flow thereof, such that a functioning of the condensation trap is guaranteed, in particular with relation to the heat energy drawn from the process gas by the condensation trap. The temperature and the volumetric flow can be influenced by means of a throttle (26), a heat exchanger (32), inside the soldering furnace, or a mixer (22). By minimizing the heat energy withdrawn by the condensation trap, the energy balance for the soldering and purification process can be optimised, such that energy can be saved to advantage. The condensation trap can also be operated with optimal efficiency, such that an embodiment of the condensation trap with comparatively small capacity is possible. The invention further relates to a soldering furnace (11) with an internal heat exchanger (32) for the process gas for purification and a purification system (21) with a control unit for adjustment of temperature and/or volumetric flow of the gas for purification.
