Feedwater heaters are used to preheat boiler feedwater by condensing steam extracted from several stages of the steam turbine. Feedwater heaters enhance the thermal efficiency of the power plant by reducing the amount of fuel burned in the boiler to produce a specified power. At the same time, the steam energy extracted from the turbine by the feedwater heater helps to reduce the rate of energy rejection to the environment via the condenser.

Mercury emissions from power plants in 137 United Nations member countries could be subject to strict controls and reductions if an international treaty is signed by participating nations this October.

Controversy concerning natural gas exports flared the day the U.S. Energy Information Administration (EIA) released its estimate that U.S. natural gas exports could begin in 2021.

Four bouts of dense smog described as the worst air pollution in recent memory enveloped more than half of China in January, from the Beijing-Tianjin-Hebei triangle in the north of the country to Nanjing in the south, via the central city of Wuhan.

More and more electricity is generated by natural gas. This trend is likely to persist. Hydraulic fracturing technology is increasing domestic supplies and enabling natural gas prices to remain at historic lows.

Here are some of the longest pipelines recently built as well as noteworthy ones in the pipeline.

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.

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.
