An air pollution control device used to filter particulates from waste combustion gases; a chamber containing a bag filter.

The maximum load that a generating unit, power plant, or other electrical apparatus can carry under specified conditions for a given period of time, without exceeding its approved limits of temperature and stress.

Binary cycle systems can be used with liquids at temperatures less than 350 F (177 C). In these systems, the hot geothermal liquid vaporizes a secondary working fluid, which then drives a turbine.

A cell produces electric energy by the galvanic oxidation of carbon; commonly used in household appliances.

A turbine in which the flow of a steam or gas is essentially parallel to the rotor axis.

An agency of the U.S. Dept. of Agriculture that makes loans to states and territories in the U.S. for rural electrification and the furnishing of electric energy to persons in rural areas who do not receive central station service. It also furnishes and i ...

Power generated by a utility unit that operates at a very high capacity factor.

A vessel or tank where heat produced from the combustion of fuels such as natural gas, fuel oil, or coal is used to generate hot water or steam for applications ranging from building space heating to electric power production or industrial process heat.

A type of air compressor in which air is compressed in a series of stages as it flows axaily through a decreasing tubular area.

The load that a power generation unit or other electrical apparatus or heating unit is rated by the manufacture to be able to meet or supply.

The difference between net electrical system capability and system maximum load requirements (peak load); the margin of capability available to provide for scheduled maintenance, emergency outages, system operating requirements and unforeseen loads.

The device in an air conditioner that distributes the filtered air from the return duct over the cooling coil/heat exchanger. This circulated air is cooled/heated and then sent through the supply duct, past dampers, and through supply diffusers to the liv ...

A type of ceiling and roof assembly that has no attic.

Any number of solar photovoltaic modules or solar thermal collectors or reflectors connected together to provide electrical or thermal energy.

An electrical device that adjusts the leading current of an applied alternating current to balance the lag of the circuit to provide a high power factor.

The incremental cost to an electric power producer to generate or purchase a unit of electricity or capacity or both.

An electromagnetic ballast that disconnects a lamp's electrode heating circuit once is has started; often called "low frequency electronic" ballasts.

A reserve appliance; for example, a standby generator for a home or commercial building.

The minimum demand experienced by a power plant.

A method of growing large size, high quality semiconductor crystal by slowly lifting a seed crystal from a molten bath of the material under careful cooling conditions.
