The form of energy used most frequently to heat the largest portion of the floorspace of a structure. The energy source designated as the main heating fuel is the source delivered to the site for that purpose, not any subsequent form into which it is transformed on site to deliver the heat energy (e.g., for buildings heated by a steam boiler, the main heating fuel is the main input fuel to the boiler, not the steam or hot water circulated through the building.) Note: In commercial buildings, the heating must be to at least 50 degrees Fahrenheit.
Industry:Energy
Steel Works, Blast Furnaces (Including Coke Ovens), and Rolling Mills Establishments primarily engaged in manufacturing hot metal, pig iron, and silvery pig iron from iron ore and iron and steel scrap; converting pig iron, scrap iron, and scrap steel into steel; and in hot-rolling iron and steel into basic shapes, such as plates, sheets, strips, rods, bars, and tubing.
Industry:Energy
The separation, or dissolving-out from mined rock of the soluble uranium constituents by the natural action of percolating a prepared chemical solution through mounded (heaped) rock material. The mounded material usually contain slow grade mineralized material and/or waste rock produced from open pitor underground mines. The solutions are collected after percolation is completed and processed to recover the valued components.
Industry:Energy
A system of pipes for transporting gas within a distributing gas utility's retail service area to points of connexion with consumer service pipes.
Industry:Energy
Nuclear fuel that has been exposed to radiation in the reactor core at any power level.
Industry:Energy
The amount of heat energy available to be released by the transformation or use of a specified physical unit of an energy form (e.g., a tonne of coal, a barrel of oil, a kilowatthour of electricity, a cubic foot of natural gas, or a pound of steam). The amount of heat energy is commonly expressed in British thermal units(Btu). Note: Heat content of combustible energy forms can be expressed in terms of either gross heat content (higher or upper heating value) or net heat content (lower heating value), depending upon whether or not the available heat energy includes or excludes the energy used to vaporise water (contained in the original energy form or created during the combustion process). The Energy Information Administration typically uses gross heat content values.
Industry:Energy
That portion of operating expenses consisting of labor, materials, and other direct and indirect expenses incurred for preserving the operating efficiency and/or physical condition of utility plants used for power production, transmission, and distribution of energy.
Industry:Energy
A normally gaseous branch-chain hydrocarbon. It is a colourless paraffinic gas that boils at a temperature of 10.9 degrees Fahrenheit. It is extracted from natural gasor refinery gas streams.
Industry:Energy
Heating and/or cooling equipment that,during the heating season, draws heat into a building from outside and, during the cooling season, ejects heat from the building to the outside. Heat pumps are vapor-compression refrigeration systems whose indoor/outdoor coils are used reversibly as condensers or evaporators, depending on the need for heating or cooling.
Industry:Energy
The cost of labor, material, and expenses incurred in the maintenance of a steam plant. Includes furnaces; boilers; coal, ash-handling, and coal-preparation equipment; steam and feed water piping; and boiler apparatus and accessories used in the production of steam, mercury, or other vapour to be used primarily for generating electricity. The point at which an electric steam plant is distinguished from an electric plant is defined as follows:
1. Inlet flange of throttle valve on prime mover.
2. Flange of all steam extraction lines on prime mover.
3. Hot well pump outlet on condensate lines.
4. Inlet flange of all turbine-room auxiliaries.
5. connexion to line side of motor starter for all boiler-plant equipment.
