Boiler Conversion: Converting a Boiler from Burning Bituminous Coals to PRB Coals Can Be a Challenge
Design techniques and operating experience with Powder River Basin (PRB) coals have advanced significantly over the past 35 years for boilers that were originally designed for this fuel. Today, boiler installations looking to effectively utilize PRB coals fall into two primary categories: units that were initially designed for bituminous or other coals and units that […]

Case Histories: Co-Firing Coal and Oat Hulls Reduces Emissions at University Power Plant
The University of Iowa (UI) Biomass Fuel Project has produced significant reductions in greenhouse gas emissions, regulated boiler stack emissions, and purchased energy costs. The project utilizes a renewable, biomass fuel source and provides an opportunity for UI to partner with a local industry. UI was approached by Quaker Oats Co., Cedar Rapids Facility in […]

Case Histories: Asheville Power Station’s Retrofit First to Meet North Carolina’s Clean Smokestacks Act
Asheville Power Station’s Unit 1 in Arden, North Carolina, was the first coal-fired unit to be modified with a flue gas desulphurization (FGD) system and placed in service to meet the clean air requirements of the state’s Clean Smokestacks Act. As of November 16, 2005, at least 97% of the sulfur dioxide that had been […]

Case Histories: Synthetic Oil and Enhanced Filtration Reduce Wear and Extend Gear Life
A coal-fired power plant operating in the western U.S. was experiencing short gearbox life in its coal-pulverizing operation. After an annual gearbox inspection, oil analysis results indicated that the AGMA 6EP (ISO 320) gear oil recommended by the original equipment manufacturer (OEM) had failed to provide adequate lubrication and protection. This conclusion was based on […]

Coal Users Community: Growth Is the Byword for Gasification
The Gasification Technologies Council (GTC, www.gasification.org) was created in 1995 with a straightforward mission: to promote the greater use of gasification as an environmentally and economically preferred alternative for the production of power, fuels, and chemicals from low-value energy sources. Those energy sources include high-sulfur coal, petroleum coke, and wastes. Since that time the GTC […]

Editorial: Tax Credits Should Help Promote Coal-Based Power Generation Technologies
In order to promote coal-based technologies, the U.S. Department of Energy will be assisting the Internal Revenue Service (IRS) in the selection of projects to receive tax credits. According to the DOE’s Office of Fossil Energy, recent legislation has been designed to advance cleaner coal-based power generation and gasification technologies. The Energy Policy Act of […]

Banana republic
Learning theorists tell us that one of the key reasons we don’t learn from our mistakes is that we don’t or won’t recognize them as such. We attribute good outcomes to our skill and intelligence and blame bad ones on others or on just plain bad luck. This unhealthy mind-set can be tolerated for […]

Profiling your plant engineering staff
The latest benchmarking study by the EUCG examines the engineering and technical staffing of 62 plants, 92% of which burn coal. If you benchmark your units, plants, or fleet, the results may raise some eyebrows. But they also may help justify your plea for more intellectual capital during the upcoming budgeting cycle. Though the detailed results of the study are proprietary to EUCG member companies that participated in it, POWER was given access to the complete findings. If you want details at the plant/unit level, you’ll have to join the EUCG and participate in the study, which is ongoing.
