    • Steam is generated using high total dissolved solids (TDS) boiler feedwater while still maintaining relatively low boiler blowdown rates. In one embodiment, a boiler is adapted to generate low quality steam from the high TDS feedwater to maintain wet conditions in the boiler tubes to mitigate against fouling/scaling problems. The low quality steam is then separated into a vapor fraction and a liquid blowdown stream. The vapor fraction is superheated to superheated steam. The liquid blowdown stream is allowed to exchange heat with the thus-created superheated steam to vaporize a portion of the blowdown to form a finished steam and a waste stream. This reduces the blowdown to waste and creates more end user steam. The finished steam is routed to its end use, e.g., a hydrocarbon thermal recovery process. Advantages include lower cost, higher efficiency, and less equipment complexity.
    • 使用高总溶解固体(TDS)锅炉给水产生蒸汽,同时仍然保持较低的锅炉排放率。 在一个实施例中,锅炉适于从高TDS给水产生低质量的蒸汽,以保持锅炉管中的湿条件以减轻结垢/结垢问题。 然后将低质量蒸汽分离成蒸汽馏分和液体排放流。 蒸汽馏分过热到过热蒸汽。 允许液体排放流与由此产生的过热蒸汽进行热交换,以蒸发一部分排污以形成成品蒸汽和废物流。 这减少了浪费的排污,并创造了更多的最终用户蒸汽。 完成的蒸汽路线到其最终用途,例如烃热回收过程。 优点包括降低成本,提高效率,减少设备复杂度。
