  • Boiler Water Feeding -- On/Off vs. Modulating
    The question facing many consulting engineers today is whether to specify on/off operation or modulating continuous feed when boiler size is between 250 and 1200 horsepower. To answer this question, it is important to understand the difference between the two. Fig. 1 shows a typical on/off piping
  • 16 Steps to Proper Boiler-Feed-Pump Selection
    When selecting a feed pump for an industrial steam boiler, there are a number of steps to take into account to ensure safe operation. A steam boiler is a pressurized tank, and it is critical that it always has the correct amount of water to avoid a boiler meltdown. For this and other reasons

In August 1998, the Flying J Petroleum Refinery replaced its hot lime softener, which removes hardness and alkalinity from boiler feed water, with a reverse osmosis unit. The benefits of this replacement project include lower
  • Approaches to Produced Water Treatment Evolving
    Heavy-oil fields throughout North America are now fully engaged in utilizing produced water as boiler feed for thermal extraction - a more reliable, environmentally friendly approach compared to using fresh water. However, the methods for treating produced water are swiftly evolving, in interesting
  • Power Plant in Thailand Uses Liqui-Cel (R) Membrane Contactors to Remove CO2 From Water (.pdf)
    A major power plant in Thailand is using Liqui-Cel (R) Membrane Contactors to remove carbon dioxide from a DI water system. The system is an expansion project and will be used to feed a high pressure boiler. Liqui-Cel Contactors are being used to lower the CO2 inlet into an Ionpure EDI system
  • Bringing Energy Efficiency and Cost Savings to Veteran's Facilities
    your system with accurate steam flow measurement. How much water are you using for key processes?. In boiler tuning, the feed water flow to the boiler is an important measurement, since you need to measure the efficiency at which the boiler turns this feed water into steam. You may also need
