Abstract:
Apparatus for generating steam is disclosed. It comprises a water inlet (19), an evaporation surface (24), and a heater (26) disposed adjacent to the evaporation surface to heat the evaporation surface. The water inlet (19) is positioned relative to the evaporation surface (24) so that water is fed onto the evaporation surface from the inlet (19) and forms a film on the evaporation surface such that said film is evaporated from the evaporation surface (24). The apparatus also has a scale collection region (23). The evaporation surface (24) and the scale collection region (23) are configured such that the scale collection region (23) is positioned below the evaporation surface (24) during use of the apparatus so that scale dislodged from the evaporation surface (24) and which falls away from the evaporation surface (24), drops into the scale collection region (23).
