• Obama Administration’s Environmental Rules to Leave Lasting Legacy on Power Sector, Markets

    Witnesses at a Congressional hearing raised concerns about the complexity, costs, legality, and feasibility of the 3,900 final rules published by the Environmental Protection Agency (EPA) during the Obama administration.

  • Why Is Insulation Important In Steam System Thermal-Cycle Efficiency?

    A proactive insulation-management program is critical to overall steam system thermal-cycle efficiency. Furthermore, because steam systems operate above 212°F (100°C) and as high as 1200°F (649°C), the negative effects of uninsulated components can be dramatic and are unacceptable in today’s industrial steam system operation.

  • A Different Perspective: Refractory Materials for the Power Generation Industry

    Refractory has always been an integral part of boiler design. However, because it is one of the smallest of the boiler components, it sometimes does not get the attention it deserves. Paying attention to the refractory material selection on new or existing boilers can and will help ensure efficient boiler operation and contribute to energy

  • A Further Understanding of Boiler MACT for Area and Major Sources

    This article is a follow-up to the piece that appeared in the November issue of Insulation Outlook. The U.S. national elections appeared to have the expected, definitive effect on the high-profile Industrial Boiler Maximum Achievable Control Technology (MACT) regulation. As discussed in November’s article, the regulation’s two subparts have undergone many changes and much scrutiny

  • Understanding the Boiler MACT Regulation for Area and Major Sources

    Rarely is it that a specific environmental regulation becomes so high profile as the recent Industrial Boiler Maximum Achievable Control Technology (Boiler MACT) regulation, which has been the subject of myriad bills that have come before the U.S. Congress. The Boiler MACT has been cited as a clear division point between the two major political

  • Five Tips for Achieving Furnace Lining Efficiency

    An efficient furnace lining is key to reducing overall maintenance costs and ensuring that facilities run smoothly without undue revenue loss due to downtime. Follow the five tips below to keep your furnace lining running efficiently. Tip 1: Evaluate the furnace liner by using infrared (IR) thermography inspection. Infrared (IR) thermography scans are an essential

  • A Different Perspective: Going Green with Alternative Fuel Burning Boilers

    “Going green” – accomplishing thermal and energy efficiency – is the new buzzword, and much is being written about how the steam-generating industry has to go green. However, the steam-generating industry has been working on this for years with clean coal technology designs and biomass- and refuse-firing boilers. And now that new fields that could

  • Corrosion and Lagging Problems in Power Plants

    Improperly designed and installed lagging systems can lead to plate corrosion and gas or air leaks on flues, ducts, and equipment. It is estimated that plate corrosion and flue/air leaks cost the power industry millions of dollars in repairs annually. Plate corrosion will always lead to gas or air leaks, and the root cause is

  • What the Power Industry Should Know about Cyclone Boilers

    A cyclone-fired boiler is designed to burn crushed coal to generate electricity. It is just one of many boiler types designed to burn coal. Coal-fired boilers generate over 55 percent of U.S. electric power. The boilers with the highest capacity (by megawatt) are designed to burn either pulverized coal (PC) or crushed coal. The PC-fired

  • Drying Refractory in Steam-Generating Boilers

    Drying refractory is critical for strong, long-lasting refractory applications. Unfortunately, standard refractory dry-out schedules, provided by all refractory manufacturers with their products, are difficult to apply to refractory used on a steam-generating boiler. These standard dry-out schedules are generic and require temperature monitoring rarely found at power plants, where monitoring capabilities are limited. Power plants
