Abstract: Systems and methods relate to vaporizing water into steam, which may be utilized in applications such as bitumen production. Initial indirect vaporization of the water at a first pressure for treatment precedes a steam generator boiling the water at a second pressure higher than the first pressure. The indirect vaporization of the water occurs in a vessel upon contact of the water with a substance such as solid particulate heated to a temperature sufficient to vaporize the water. Impurities in the water deposit on the solid particulate and/or combust limiting pass through of the impurities to the steam generator given that a vapor output of the vessel from the initial indirect vaporization condenses and is pressurized before being supplied to the steam generator.
