Plant Design

This synopsis of today’s most interesting research related to power generation gives you a glimpse of what’s possibly coming to your plant in the not-so-distance future. Research under way today will surely determine how power plants are designed, operated, and maintained for many years to come.

Insulation and lagging are key to saving energy in a typical steam plant, and plant operators would be well advised to pay close attention to energy losses in their insulation and lagging systems.

The world’s first supercritical pulverized coal–fired low mass flux vertical tube Benson boiler is Jinzhushan 3, located in Hunan Province of the People’s Republic of China. The 600-MW Babcock & Wilcox Power Generation Group Inc. once-through boiler burns Chinese anthracite using downshot pulverized coal (PC) technology. Part 2 of this three-part article discusses the boiler technology. The third and final part will review the plant’s performance test results.

Dominion Virginia Power plans to convert its oldest coal-fired power plant, the 227-MW Bremo Power Station near Bremo Bluff, Va., to natural gas, the company announced earlier this month. The two-unit plant would be the ninth in its fleet to be closed or converted to alternative fuels.

The world’s first supercritical pulverized coal–fired low mass flux vertical tube Benson boiler is Jinzhushan 3, located in the Hunan Province of the People’s Republic of China. The 600-MW Babcock & Wilcox Power Generation Group Inc. once-through boiler burns Chinese anthracite using downshot pulverized coal (PC) technology. Part 1 of this three-part article provides a project summary and overview. The other two parts will look at technology features of the unique boiler design and plant performance test results.

Advanced ultrasupercritical (A-USC) is a term used to designate a coal-fired power plant design with the inlet steam temperature to the turbine at 700C to 760C. In the first two parts of this three-part report, we introduced the A-USC boiler and the metallurgical advancements required for the A-USC boiler to operate at such high temperatures. This final report explores the A-USC boiler’s unique design challenges.

Trying to assess the potential for coal-to-gas switching in today’s environment is something of an art form. Suppose for a moment that one were able to devise an economic model that truly replicates real-world generation dispatch for plant operators. A model is only as good as the inputs that go into it, and, let’s face it, future natural gas prices are a critical component.

Coal combustion products often can be recycled into a variety of construction and building materials. However, first you must be able to retrieve the wet ash from a holding pond before the ash can be dried and sold.

Advanced ultrasupercritical (A-USC) is a term used to designate a coal-fired power plant design with the inlet steam temperature to the turbine at 700C to 760C. In Part I of this three-part report, we introduced the A-USC boiler. In this segment, we look at the metallurgical advancements required for the A-USC boiler to operate at such high temperatures. The final report will explore the A-USC boiler’s unique design challenges.

Advanced ultrasupercritical (A-USC) is a term used to designate a coal-fired power plant design with the inlet steam temperature to the turbine at 700C to 760C. In Part I of a three-part report, we introduce the A-USC boiler. Future reports will discuss the metallurgical and boiler design challenges.
