  • Application notes: The Sievers InnovOx TOC analyzer: boiler water monitoring

    Background A boiler system is a semi-closed loop system in which water is heated and converted into steam to power a generator. The steam is then allowed to form a condensate and the process is repeated. Boiler water chemistry directly impacts boiler efficiency and fuel use. Improper water treatment allows scale formation and corrosion. Boiler scale and deposits form when impurities ...

  • Preventing scaling caused by hard water without the use of chemicals ... a unique green technology

    Preventing scaling caused by hard water without the need to use chemicals. A unique green technology.Scaling caused by hard water is a worldwide problem it builds up in process systems, heating systems, air condi¬tioning systems and even irrigation systems. Traditional methods to prevent it involve water softening, deminer¬alisation or the addition of chemicals. All of which are expensive and ...

  • Energy and exergy analyses of a supercritical power plant

    Energy and exergy efficiencies of a supercritical power plant have been studied in this paper. The effect of ambient weather condition was considered on the condenser pressure. It was shown that high ambient temperature has more adverse effect on the exergy efficiency than the energy efficiency. As ambient temperature increases, the exergy efficiency of the boiler, condenser, heaters and feed ...

  • GEM condensate return system projects

    Most of the Coca-Cola consumed in Northern Ireland comes from the company’s Lambeg bottling plant. An assessment was conducted on the steam trap needs for the water heater of the company’s large bottle washer and bucket tests showed variable flow up to a quarter of a tonne of steam per hour. The two inverted bucket steam traps in the system were proving unreliable, so they were replaced with two ...

  • Case study - Spindle utilities module

    Business Situation The existing method of tracking utility usage at these industrial laundries was highly manual, unreliable, and time consuming. Total utility consumption from bills was entered into large spreadsheets and analyzed over periods that were often 3 months or more in arrears. The report merely told managers what they already knew—they had overspent on natural gas; ...

  • Pumps for synthetic heat-transfer liquids

    As soon as the temperature in a heat-transfer system becomes too high for water, a plant operator must choose between petroleum-based or synthetic oils as the heat-transfer liquid. When modern petroleum oils are used, systems with feed temperatures up to about 300 °C can stay in service for their entire service life with one filling and with virtually no maintenance. Once feed temperatures ...
