Abstract:
1. An evaporation unit for the evaporation of an aqueous solution including at least one reducing agent precursor, the evaporation unit comprising: a wall made of a material including titanium, said wall delimiting at least one evaporator cavity; a heat-imparting layer made of a material with a thermal conductivity of at least 100 W/mK (Watts per meter and Kelvin), said heat-imparting layer lying outside said evaporator cavity and being thermally conductively connected to said evaporator cavity; and a heating layer disposed outside of said heat-imparting layer and being materially integrally connected to said heat-imparting layer, said heating layer including a first heating zone and a second heating zone disposed next to said first heating zone in a direction of flow of the aqueous solution within said evaporator cavity, said second heating zone being operable independently of said first heating zone and being configured for operating at a higher temperature than said first heating zone.
