How to conduct a plant performance test

Performance testing after initial start-up has value well beyond the short-term goal of validating equipment guarantees—it’s your only opportunity to establish the baseline performance of the overall plant and many of its major systems. Corporate bean counters may be interested in short-term results, but a good plant engineer understands that a thorough performance test will be useful for many years. Here’s your guide to each facet of a performance test—plus pitfalls to avoid.

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 […]

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 […]

Scrubbing: Optimizing Flue Gas Desulfurization Technologies Is Essential

New flue gas desulfurization (FGD) units are being installed at utilities in many parts of the U.S. and a large percentage of the new scrubbers are of the wet limestone type. Although wet limestone scrubbing is a well-developed technology, it may be unfamiliar to employees at plants that have previously not required scrubbers. This article […]

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.
