You may be surprised to learn that even with the increased demand for biomass fuels for power generation, construction and demolition fuel is classified as solid waste, not biomass. Reconsidering this designation is critical as U.S. environmental regulations tighten emission profiles for solid waste combustion units and renewable portfolio standards expand.

The lifeblood of the combined cycle plant is its water chemistry program. This is particularly true for plants designed for high pressures and temperatures as well as fast starts and cycling. Even though such plants are increasingly common, no universal chemistry program can be used for all of them.

Recent reports by the National Renewable Energy Laboratory and others suggest that the emissions-reducing benefits of renewable energy sources such as wind and solar may have been overstated and the cost of cycling fossil-fueled plants underestimated. These findings may change how utilities and policymakers weigh the costs and benefits of wind and solar energy.

Steam turbine blade cracking often suggests the need for an upgraded blade design. Follow the process of reversing engineering a failed blade to produce a more reliable and efficient design.

A new modular and durable quick-release mount for popular fire-extinguisher sizes is now available from Off-Road Solutions (ORS). The system uses two pieces of 6061-T6 billet aluminum: one attaches to the extinguisher while the other piece secures to a fixed object. The 3/16-inch hinge pin and 3/8-inch quick-release pull pin with detent ball are made […]

Filtersense’s new continuous particulate emissions monitor and baghouse leak detector incorporates “Automatic Zero and Span Checks” to eliminate manual calibration audits, as required by the U.S. Environmental Protection Agency (EPA) for Maximum Achievable Control Technology (MACT) standards and other regulations for fabric filter particulate emissions monitoring. In addition to internal self-checks, the company’s field-proven induction-sensing […]

ATCO Emissions Management (ATCO) announced the addition of heat recovery steam generators (HRSGs) to its line of gas turbine auxiliary equipment for the power, oil, gas, and cogeneration markets. The new HRSG product, an energy recovery heat exchanger that recovers heat from a hot gas stream, will initially serve facilities with gas turbines up to […]

Most professionals in the energy industry know about biomass; fewer of us are conversant with biogas. This commentary explains the basics of biogas, with a focus on its current use and future potential as a source of electrical power.

Japan’s scramble to replace generation lost from nuclear power plants that were shuttered after the March 2011 Fukushima Daiichi nuclear accident has forced it to rely on pricey imports of fossil fuels—and soaring energy costs are hammering the world’s third-largest economy.

A pervasive drought in northeast Brazil has dried up power supplies from the region’s hydropower facilities, making the area prone to blackouts and crippling economic growth in one of the country’s emerging agricultural havens.
