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 […]

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 […]

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: 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 […]
