biomass energy | National Geographic Society

However, converting biomass into pellets (as opposed to wood chips or larger briquettes) can increase the fuels energy density and make it more advantageous to ship. Burning biomass releases carbon monoxide, carbon dioxide, nitrogen oxides, and other pollutants and particulates.

Biomass for Electricity Generation | WBDG - Whole Building

Sep 15, 2016 · In a direct combustion system, processed biomass is the boiler fuel that produces steam to operate a steam turbine and generator to make electricity. Types and Costs of Technology There are numerous companies, primarily in Europe, that sell small-scale engines and combined heat and power systems that can run on biogas, natural gas, or propane.

Anaerobic digestion - Wikipedia

Anaerobic digestion is a sequence of processes by which microorganisms break down biodegradable material in the absence of oxygen. The process is used for industrial or domestic purposes to manage waste or to produce fuels. Much of the fermentation used industrially to produce food and drink products, as well as home fermentation, uses anaerobic digestion.

Internal combustion engine - Wikipedia

An internal combustion engine (ICE) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine.

Fossil fuel power station - Wikipedia

A fossil fuel power station is a thermal power station which burns a fossil fuel, such as coal or natural gas, to produce electricity.Fossil fuel power stations have machinery to convert the heat energy of combustion into mechanical energy, which then operates an electrical generator.The prime mover may be a steam turbine, a gas turbine or, in small plants, a reciprocating gas engine.

The systems help prevent the creation of nitrogen oxides with a resulting reduction in NOx emissions of about 40 per cent. In 2012 Nova Scotia Power announced that two of Lingan's units would be operated only on a seasonal basis due to decreased industrial load, increased renewable energy use and to meet environmental requirements.
