  • DM make up water reduction in thermal power plants

    2008-4-7  DM water is used for steam generation through gas based combined cycle power plant. W ith in this closed cycle of DM water, DM water make up cycle is required to compensate for the losses incurred in water-steam cycle due to evaporation, start up and shut down venting, valve passing and blow downs. DM make up water enters in a

  • DM Make up Water Reduction in Power Plants Using

    2017-3-31  DM water is of two kinds – cyclic and non-cyclic DM. Cyclic dm water is that which is a part of steam cycle and non cyclic dm water is used in various applications like Stator water, SG ECW/ TG ECW etc. Here our focus is on cyclic DM water consumption only. Calculations are based on six months dm water trend of unit - 3 of stage- 1 dadri

  • Demineralized Water - an overview ScienceDirect

    J. Tominaga, in Advances in Steam Turbines for Modern Power Plants, 2017 3.3.1 Cycle and features of BWRs. A BWR generates steam from demineralized water in the reactor itself, and uses the steam directly to drive the steam turbine. The configuration is simple compared to PWR which has steam generators, and the reactor pressure vessel (RPV) of BWR is designed in lower pressure conditions

  • What Are the Properties of Demineralized Water and

    2018-3-26  Boilers that generate steam to power turbines require high-pressure boilers and therefore more complex feed water treatment system to remove as many impurities as possible. When steam is produced inside the boiler, the water particles collect and condense, then are recycled and used as part of the boiler feed water.

  • Boiler Feed Water Treatment Demineralization

    2012-2-24  For continuous supply of feed water to boiler, after removing impurities, there are two types of plant generally incorporated. These are: Demineralization plant (D M plant); Reverse Osmosis plant (R O plant); Demineralization plant employs a chemical method to separate out the dissolved salt in raw water. But reverse osmosis plant employs a simple physical method to separate the dissolved salts.
