Section 1112-2.0 - Definitions

As used in this subpart, all terms not defined herein shall have the meaning given them in the Clean Air Act and 7 DE Admin. Code 1101.

"Building, structure, facility, or installation" means all of the pollutant emitting activities which belong to the same industrial grouping, are located on one or more contiguous or adjacent properties, and are under the control of the same person (or persons under common control). Pollutant-emitting activities shall be considered as part of the same industrial grouping, if they belong to the same "Major Group" (i.e.,which have the same first two digit code) as described in the Standard Industrial Classification Manual, 1987.

"Capacity factor" means the ratio of the average load on a machine or equipment for the period of time considered to the capacity rating of the machine or equipment.

"Flue gas recirculation" means recirculating a fraction of the flue gas to the burners to reduce peak flame temperature and oxygen availability with vitiated air for NOx reduction.

"Fuel burning equipment" means each unit used for the burning of fuel or other combustible material for the primary purpose of utilizing the thermal energy released.

"Gas turbine" means an internal combustion engine that operates with rotary motion, is fueled by liquid or gaseous fuel, and may employ one of three types of combustors: annular, can-annular, or silo.

"Internal combustion engine" means a reciprocating engine which is fueled by liquid or gaseous fuel, produces heat or pressure developed in the engine cylinder or cylinders by burning a mixture of air and fuel, and is subsequently converted to mechanical work by means of a piston or pistons.

"Lean burn technology" means adjusting the air-to-fuel mixture ratio for reducing NOx emission.

"Liquid fuel" means oil, kerosene, and other light petroleum product not technically termed oil.

"Low excess air" means operation with minimal combustion air to optimize thermal efficiency and reduce NOx formation.

"Low NOx burner technology" means burner and windbox assemblies designed to minimize the formation of NOx by various techniques, separated fuel jets, and controlled air mixing.

"Major nitrogen oxides (NOx) emitting source" means a stationary source which emits or has the potential to emit nitrogen oxides at a rate equal to or greater than 25 tons per year in New Castle and Kent Counties and equal to or greater than 100 tons per year in Sussex County.

"Potential to Emit" means the maximum capacity of a stationary source to emit nitrogen oxides under its physical and operational design and maximum operating hours (8760 hours/year) before add-on controls. Any physical or operational limitation on the capacity of the source to emit nitrogen oxides before add-on controls, such as restrictions on hours of operation or on the type or amount of material combusted, stored, or processed, shall be treated as part of its design, if the limitation or effect it would have on emissions is state and federally enforceable.

"Pre-ignition chamber combustion" or "cleanburn" means NOx control approach where cylinder heads are structured with small, separately fed, combustion chambers where a rich mixture is ignited by a spark plug, combusted, and then expanded into a very lean mixture in the main combustion chamber.

"Reasonably Available Control Technology (RACT)" means the lowest emission limit for NOx that a particular source is capable of meeting by the application of control technology that is reasonably available considering technological and economic feasibility.

"Stationary source" means any building, structure, facility, or installation which emits or may emit nitrogen oxides.
