RULE 260.331 - DEFINITIONS
(Rev. Effective 11/24/82)

As used in this subpart, all terms not defined herein shall have the meaning given them in the Act and in Subpart A of this Regulation.

(a) "Stationary Gas Turbine" means any simple cycle gas turbine, regenerative cycle gas turbine or any gas turbine portion of a combined cycle steam/electric generating system that is not self-propelled. It may, however, be mounted on a vehicle for portability.

(b) "Simple Cycle Gas Turbine" means any stationary gas turbine which does not recover heat from the gas turbine exhaust gases to preheat the inlet combustion air to the gas turbine, or which does not recover heat from the gas turbine exhaust gases to heat water or generate steam.

(c) "Regenerative Cycle Gas Turbine" means any stationary gas turbine that recovers thermal energy from the gas turbine exhaust gases and utilizes the thermal energy to preheat air prior to entering the combustors. (Rev. Effective 11/24/82)

(d) "Combined Cycle Gas Turbine" means any stationary gas turbine which recovers heat from the gas turbine exhaust gases to heat water or generate steam.

(e) "Emergency Gas Turbine" means any stationary gas turbine which operates as a mechanical or electrical power source only when the primary power source for a facility has been rendered inoperable by an emergency situation.

(f) "Ice Fog" means an atmospheric suspension of highly reflective ice crystals.

(g) "ISO Standard Day Conditions" means 288 degrees Kelvin, 60 percent relative humidity and 101.3 kilopascals pressure.

(h) "Efficiency" means the gas turbine manufacturer's rated heat rate at peak load in terms of heat input per unit of power output based on the lower heating value of the fuel.

(i) "Peak Load" means 100 percent of the manufacturer's design capacity of the gas turbine at ISO standard day conditions.

(j) "Base Load" means the load level at which a gas turbine is normally operated.

(k) "Fire-Fighting Turbine" means any stationary gas turbine that is used solely to pump water for extinguishing fires.

(l) "Turbines Employed in Oil/Gas Production or Oil/Gas Transportation" means any stationary gas turbine used to provide power to extract crude oil/natural gas from the earth or to move crude oil/natural gas, or products refined from these substances through pipelines.

(m) [Reserved] (Rev. Effective 11/24/82)

(n) "Offshore Platform Gas Turbines" means any stationary gas turbine located on a platform in an ocean.

(o) "Garrison Facility" means any permanent military installation.

(p) "Gas Turbine Model" means a group of gas turbines having the same nominal air flow, combustor inlet pressure, combustor inlet temperature, firing temperature, turbine inlet temperature and turbine inlet pressure.

(q) "Electric Utility Stationary Gas Turbine" means any stationary gas turbine constructed for the purpose of supplying more than one-third of its potential electric output capacity to any utility power distribution system for sale. (Effective 11/24/82)

(r) "Emergency Fuel" is fuel fired by a gas turbine only during circumstances, such as natural gas supply curtailment or breakdown of delivery system, that make it impossible to fire natural gas in the gas turbine. (Effective 11/24/82)
