COAL POWER Direct

Reducing dust from coal conveyors has moved from a housekeeping chore to a safety challenge, especially with Powder River Basin coals. Here’s what you need to know about the latest coal-handling system design.

The EPA has identified 44 "high hazard" coal ash ponds around the U.S., and a recent Tennessee Valley Authority report indicates that the agency should have known its Kingston Plant pond would have been one of them.

An analysis by the Center on Budget and Policy Priorities concluded that two-thirds of the value of carbon emission allowances described by the recent H.R. 2545 will benefit utility business customers and households in the top quartile of personal income. The middle quintile will see increased cost for electricity.

MIT researchers push for faster commercialization of carbon capture technologies for coal-fired power plants by reducing system costs.

A policy of allocating free allowances to hold down electric price increases, as some in our industry are advocating as part of climate change legislation, is well-intended but not the best choice for a cap-and-trade plan. An "auction and recycle" plan accomplishes the same goals yet is more consumer friendly.

Of the 131 million tons of U.S. power plant waste or coal combustion by-products (CCBs), 36% are disposed of in landfills and 21% are disposed of in surface impoundments. Recent problems with surface impoundments and landfills have created a media furor and have prompted elected and appointed officials to demand more stringent regulatory control.

The annual meeting of the Powder River Basin Coal Users’ Group was held in association with the ELECTRIC POWER conference in early May in Chicago. Get a taste of the festivities, technical meetings, and the announcement of the group’s 2009 Large and Small Plant of the Year winners in this conference report.

Measuring combustion airflow in a coal-fired power plant can be problematic when using annubar instruments that feature small holes that can easily plug with coal dust. Sierra Instruments eliminates this big maintenance headache with its more-accurate, nonplugging thermal mass flow meter design.

Demonstrating sound knowledge, having profound passion, and being consistent with your message are essential when trying to persuade someone to adopt your point of view. A recent press briefing hosted by a well-known pro-coal industry group failed on all counts.

New coal-fired power plant ash management regulations appear to be inevitable, perhaps as soon as year-end. The Tennessee Valley Authority and Edison Electric Institute are on board with new regulations, as long as the ash is regulated as a nonhazardous waste under the Resource Conservation and Recovery Act.
