A method and system for producing steam for extraction of heavy bitumen including the steps of mixing fuel with an oxidizing gas. Combusting the mixture and capturing portion of the combustion heat for generating steam from clean water. Mixing the combustion gas with low quality contaminated water and transferred the liquid water to gas phase with solids, wherein solids are separated from the gas phase. The gas phase is mixed with saturated water to scrub the remaining solids and produce saturated steam. The solid rich saturated water is recycled back and mixed with the combustion gases for liquid gasification. The saturated steam is condensed to generate heat and clean condensed water for steam generation. The heat can be used for evaporating additional low quality water at distillation facility to produce distilled water and concentrate brine. The brine is recycled back for liquid gasification. The high pressure steam is sent to an enhanced oil recovery facility for extract heavy oil.
