      The Importance of Condensate Return Treatment | Water Tech

      The Importance of Condensate Return Treatment. In the power industry it is well known that condensed steam from the turbine/generator must be maintained at high purity to prevent corrosion and scale formation in the boilers. But what about condensate return at other industrial facilities, where most or all of the steam is utilized for process heating, and where the steam generators may be at …

      The condensate system is subject to corrosion from oxygen, carbon dioxide, and ammonia. Condensate return lines are constructed primarily of mild steel and can be extensive in total length throughout the plant. Condensing equipment in the steam system usually includes copper or copper alloys because of its favorable heat transfer characteristics.

      Condensate return. An effective condensate recovery system, collecting the hot condensate from the steam using equipment and returning it to the boiler feed system, can pay for itself in a remarkably short period of time. Figure 14.1.4 shows a simple steam and condensate circuit, with condensate returning to the boiler feedtank.

This LPS undergoes condensation which is eventually used to generate the initial steam. Thus more the condensate recovered better is the Condensate Recovery Factor (CRF), better is the efficiency and lesser the costs of generating steam.

      However, in a condensate return system, steam is usually the inducer. Hence, hammer in a condensate system is typically steam-induced. To reduce the hammer in a condensate system, the steam in the return must be addressed. Some engineers believe that condensate return pipes are completely filled with condensate.

      Condensation Electric Power Plant | Article about

      In a condensing turbine the thermal energy of steam is converted into mechanical power, which is converted into electric power by a generator. The back-pressure steam leaving the turbine is condensed, and the condensate is pumped into a boiler (boiler unit or steam generator), first by a condensate pump and then by a feed-water pump.

      During the process of steam generation in power plants, the steam cools and condensate forms. The condensate is collected and then used as boiler feedwater . Prior to re-use, the condensate must be purified or "polished", to remove impurities (predominantly silica oxides and sodium) which have the potential to cause damage to the boilers, steam generators, reactors and turbines.

      Condensate contains a relatively large percentage (16 percent in some cases, depending on pressure) of the energy used to produce the steam. With today’s rising energy costs, facilities must return all possible condensate back to the boiler plant. The condensate should be maintained in a high-energy state or simply as hot as possible.

      Aug 04, 2016 · Condensate normally flows at the bottom of a return line with the assistance of gravity. Condensate flows naturally because of the pitch in the pipe and also because the higher-velocity flash steam above it pulls it along. The flash steam moves at a higher velocity because it moves by differential pressure. Flash steam occurs in the condensate

      A. Chiasson, in Geothermal Power Generation, 2016 15.4.1 General. In air-cooled condensers, condenser heat is rejected directly to the ambient air.Thus, the condensing temperature is a function of the ambient air dry-bulb temperature. The obvious advantage of air-cooled condensers relative to water-cooled condensers is that cooling water is not needed.
