  • Chemical Treated Steam to Culinary Steam? - Equipment

    Apr 01, 2020 · A steam generator like Miura & Clayton will not produce high quality steam, they are very efficient but high carry-over (low quality) is the trade-off. Other boiler designs with low surface area to BTU ratios will not perform as well as the Scotch Marine. Any boiler will spit out low quality steam if the load swings wildly.Learn More

  • Chemical Treatment Requirements for Steam and Hot Water

    Jun 12, 2017 · If the boiler water contains 2,000 ppm of dissolved solids, 0.5% moisture or one half pound of boiler water per 100 pounds of steam would result in a concentration of 10 ppm solids in the steam. This means that every 1 million pounds of steam delivered by the boiler would carry along 10 pounds of solids.Learn More

  • The Effects of Carryover in Steam Boiler Systems

    Effects of Carryover Boiler water carryover can cause deposits to form in valves, heat exchangers, turbines, and superheaters. If deposits are significant, heat transfer and/or turbine efficiency may be reduced. Additionally, carryover can strip away the protective magnetic layer on steam lines, remove the film formed by filming amine programs, cause erosion-induced corrosion, and result in Learn More
