The agency did not assess the economic impacts of better health from reducing nitrogen oxide in setting the new standard, ...

Combined cycle plants give greater output for the same amount of energy and emissions. But this comes at a cost—increased complexity of design and operations. Optimizing a combined cycle plant ...

The U.S. Environmental Protection Agency (EPA) last week proposed to strengthen limits on nitrogen oxide (NOx) emissions from most new and existing combustion turbines. The proposed New Source ...

The U.S. Environmental Protection Agency (EPA) proposed new standards on November 22, 2024, to significantly tighten nitrogen oxides’ (NOx) emission limits from fossil fuel-fired stationary combustion ...

The US Environmental Protection Agency (EPA) has published a draft white paper discussing control techniques and other measures that could reduce greenhouse gas (GHG) emissions from combustion ...

The agency goes easy on gas-fired steam turbines, which generally operate only when demand is high. But the units are among the country’s largest emitters of planet-warming pollution. Two steam ...

The operating profiles of traditional generators has changed to manage the variability of renewable resources. Several critical processes were not engineered to manage these highly variable operating ...

Small, ultra-fast, primary and “afterburner” secondary combustion events promise to deliver brake thermal efficiency as high as 69 percent. A better mousetrap? Even now, as electrification seems ...

Combustion noise represents a critical challenge in modern aero-engine and power generation design. It arises both from the rapid, unsteady heat release during combustion – known as direct noise – and ...
