This Section contains only terms and variations of normally used engineering definitions that are required for the implementation of this Code.
accuracy: the closeness of agreement between a measured value and the true value (see also uncertinty); the arithmetic average of a repeated measured value compared to the true value.
additive: a substance added to a gas, liquid, or solid stream to cause a desired chemical or mechanical effect.
air: the natural atmospheric mixture of nitrogen, oxygen, water vapor, carbon dioxide, argon, neon, and small quantities of other rare gases. See para. 5-9.1.
air, corrected theoretical: theoretical air adjusted for unburned carbon.
air, excess: the air supplied to burn a fuel in addition to the theoretical air necessary for complete combustion of the fuel; it is expressed as a percentage of the corrected theoretical air in this Code.
air heater: a heat exchanger that transfers heat from a high-temperature medium such as hot gas to an incoming air stream, usually recovering heat from hot gas exiting from the boiler bank or economizer.
air, infiltration: the leakage of air into the steam generator system envelope, also referred to as tramp air.
air, other: any air supplied to the systerm that is not primary or secondary air. A number of other combustion air arrangements and splits are encountered in the combustion processes covered by this C ‘ode. The user must be thoroughly familiar with the combustion air arrangement of the steam generator being tested when applying this Code.
nir preheater coils: a heat exchanger that typically uses steam, condensate, and/or glycol to heat combustion air entering the steam generator system.
air, primary: air supplied through or with a waste/ fuel to initiate and sustain combustion. This air is usually supplied through the fuel bed and may be at ambient temperature or heated to induce drying fuel; it is also referred to as undergrate air or underfire air.air, secondary: air supplied above the zone where burning is initiated. This air, at ambient temperature or heated,may be used to stimulate mixing of the burning combustible gases and suspended solids to ensure complete combustion, to reduce furnace temperature, and/or to introduce additives; it is also referred to as overfire air.ASME PTC 34 pdf free download.
