  • Best Practices for Eddy Current Testing of Heat Exchanger Tubes

    Eddy current testing (ECT)  is one of the best methods of measuring wall thickness and circumferential cracks when testing heat exchanger tubes. But it takes quality instrumentation to capture defects accurately. Heat exchanger tubes are subject to heavy stress due to high-fluid pressure, including expansions and contractions of the tubes themselves. ECT is one of the most ideal inspection ...

  • Proper Valve Trim Extends Life of Boiler Feedwater Valves

    In competitive power markets, combined cycle facilities are experiencing more operating cycles than owners initially planned for at the design stage. It’s not uncommon for a combined cycle plant to experience more than 250 starts per year these days.While the ability to cycle a large combined cycle plant is ideal for fleet flexibility, frequent startups and shutdowns strain many critical ...

  • Steam Boiler Chemicals

    Steam boilers are vessels to which heat is applied so that water is continuously converted in to steam. ‘Feed water’ is the water added to a boiler to replace that lost due to evaporation and blow down. Often steam is condensed and returned to the boiler as part of the feed water. The primary objectives in boiler design, operation and effective treatment include: efficiency in heat ...

  • KNOWING THE PLANT’S STEAM QUALITY

    Steam quality is the proportion of saturated steam (vapor) in a saturated condensate (liquid)/steam (vapor) mixture. A steam quality of 0 indicates 100% liquid (condensate), while a steam quality of 100 indicates 100% steam. One pound of steam with 95% steam and 5% of liquid entrainment has a steam quality of 0.95.The measurements needed to obtain a steam quality measurement are temperature, ...

  • District heating reduces carbon footprint – Case Study

    District heating is a system for distributing heat generated from a centralized location for residential and commercial heating requirements. The heat is often obtained from a cogeneration plant that burns fossil fuels, but increasingly these plants are transitioning to biomass. According to recent research, district heating is one of the cheapest methods of reducing carbon on the planet and has ...

  • Improve Boiler Efficiency

    In many chemical plants, the electricity the plant uses is derived from a natural gas power plant or a co-generation plant burning waste gas streams. In large boilers (Figure 1), power plants bring together air and fuel (natural gas, waste gas, oil or coal) for combustion, which creates heat. The heat boils the water, creating steam. The steam runs through a turbine, which causes the turbine to ...

  • The “Tipping” Point of High Turndown Ratios: How much of a good thing is too much?

    Boilers used for domestic water and space heating are one of the highest energy consumers in residential and commercial facilities. After the global energy crisis in the 1970s, higher fuel prices prompted the search for solutions to reduce energy consumption. Back then, conventional steam boilers were the only option available. However, these boilers were very inefficient (due in part to the ...
