Big Stone Remodels ESP into Pulse Jet Fabric Filter
Short of replacement, what are your options when your original electrostatic precipitator fails to meet your current emissions and opacity requirements? The management of Big Stone Plant chose the unconventional, yet economic approach of building a pulse jet fabric filter inside the casing of the old electrostatic precipitator. The upgrades restored plant availability and prepare the plant to meet the next regulated reductions in particulate matter emissions.

Real-Time Control of Coal Quality Improves Reliability
Poor lignite fuel quality had plagued the Red Hills Power Plant since it began operation eight years ago. The solution: real-time measurement of coal properties that has allowed Red Hills Mine to carefully monitor fuel quality and adjust fuel collection processes to ensure that only high-quality fuel is delivered to the plant. Now all delivered fuel is consumed, and plant reliability is much improved. It’s a classic win-win project.

Strategies to Reduce Sulfuric Acid Usage in Evaporative Cooling Water Systems
Concentrated sulfuric acid is often used to prevent calcium-based scale formation on condenser and heat exchanger tube surfaces in power plant evaporative cooling water systems. Unfortunately, the chemical’s price has jumped more than 300% over the past three years. If the rising cost of water treatment has you under the budget gun, here are some alternative strategies that can reduce or even eliminate your sulfuric acid usage.

Determining Carbon Capture and Sequestration’s Water Demands
The U.S. Department of Energy’s National Energy Technology Laboratory is pursuing a new integrated energy-water R&D program that addresses water management issues relative to coal-fired power generation that takes into account the major impacts of CCS on water use. The goal of this research is to promote more efficient use of water in power plant operations and increase the availability of heretofore unusable waters for power plant use. Those practices can mitigate the impacts of CCS on power plant water use and allow for continued development of energy resources.

Renewable Realities
"It’s anti-renewables" is becoming a familiar refrain voiced before public utility commissions, air quality management districts, and other public agencies with jurisdiction over the siting and operation of new fossil-fueled electric generation projects. The survival — and, in some cases, expansion — of legislatively mandated renewable energy requirements, tax incentives, and outright subsidies through the recent economic downturn has further encouraged opponents of new fossil-fueled generation to cloak themselves in the environmental flag, irrespective of their underlying motives and goals.

Level the Playing Field for Open-Loop Biomass
Congress snubbed the biomass power industry in 2004 when open-loop biomass power plants were given only half the production tax credits (PTCs) received by other renewable sources, such as wind, solar, and geothermal. It further dissed open-loop biomass plants by authorizing the credit for only five years (it expired December 31, 2009) rather than the 10 years given to other renewables. Why is the biomass power industry not getting the policy respect and equity with other renewable technologies that it deserves?
