    Radiant section:Portion of the heater in which heat is transferred to the tubes primarily by radiation


    Shield section/shock section–tubes that shield the remaining convection-section tubes from direct radiation


    Vertical cylindrical fired heater: (a) all radiant and (b) helical coil


    Horizontal tube cabin fired heaters: (a) cabin with convection section and (b) cabin with dividing bridge wall

    Air Preheater :Heat exchanger device that uses some of the heat in the flue gases to raise the temperature of the air supply to the burners.
    Breeching:The hood that collects the flue gas at the convection section exit.
    Bridge:Wall Temperature - The temperature of the flue gas leaving the radiant section
    Bulk Temperature: The average temperature of the process fluid at any tube cross section.
    Center Wall:A refractory wall in the radiant section, which divides it into two separate cells.
    Coil: A series of straight tube lengths connected by 180 o return bends, forming a continuous path through which the process fluid passes and is heated.
    Convection Section: The portion of a heater, consisting of a bank of tubes, which receives heat from the hot flue gases, mainly by convection.
    Corbelling: Narrow ledges extending from the convection section side walls to prevent flue gas from flowing preferentially up the side of the convection section, between the wall and the nearest tubes.
    Crossover:Piping which transfers the process fluid either externally or internally from one section of the heater to another.
    Damper: A device to regulate flow of gas through a stack or duct and to control draft in a heater.
    Draft:The negative pressure (vacuum) at a given point inside the heater, usually expressed in inches of water.
    Excess Air - The percentage of air in the heater in excess of the stoichiometric amount required for combustion.
    Extended Surface - Surface added to the outside of bare tubes in the convection section to provide more heat transfer area.
    Film - A thin fluid layer adjacent to a pipe wall that remains in laminar flow, even when the bulk flow is turbulent.
    Film Temperature - The maximum temperature in the film, at the tube wall.
    Fire Box - A term used to describe the structure which surrounds the radiant coils and into which the burners protrude.
    Flue Gas - A mixture of gaseous products resulting from combustion of the fuel.
    Fouling - The building up of a film of dirt, ash, soot or coke on heat transfer surfaces, resulting in increased resistance to heat flow.
    Forced Draft - Use of a fan to supply combustion air to the burners and to overcome the pressure drop through the burners.
    Fired Heater Efficiency - The ratio of heat absorbed to heat fired, on a lower heating value basis.
    Header Box - The compartment at the end of the convection section where the headers are located.
    Heat Available - The heat absorbed from the products of combustion (flue gas) as they are cooled from the flame temperature to a given flue gas temperature.
    Heat Density - The rate of heat transfer per unit area to a tube, usually based on total outside surface area.
    Heat Duty - The total heat absorbed by the process fluid, usually expressed in MBtu/hr
    Induced Draft - Use of a fan to provide the additional draft required over that supplied by the stack, to draw the flue gas through the convection section, and any downstream heat recovery equipment.
    Lower Heating Value (LHV) - The theoretical heat of combustion of a fuel, when no credit is taken for the heat of condensation of water in the flue gas.
    Mass Velocity - The mass flow rate per unit of flow area through the coil. Typical units are lb/s-sq. ft.
    Natural Draft - System in which the draft required to move combustion air into the heater and flue gas through the heater and out the stack is provided by stack effect alone.
    Net Fuel - The fuel that would be required in the heater if there were no radiation losses.
    One-Side Fired Tubes - Radiant section tubes located adjacent to a heater wall have only one side directly exposed to a burner flame. Radiation to the back side of the tubes is by reflection/ re-radiation from the refractory wall.
    Pass - A coil that transports the process fluid from fired heater inlet to outlet.
    Radiant Section - The section of the fired heater in which heat is transferred to the heater tubes primarily by radiation from high-temperature flue gas.
    Service Factor – A measure of the continuity of operation, generally expressed as the ratio of total running days for a given time period to the total calendar days in the period.
    Shield Section - The first two tube rows of the convection section.
    Sootblower - A steam lance (usually movable) in the convection section for blowing soot and ash from the tubes using high-pressure steam.
    Stack - A cylindrical steel, concrete or brick shell which carries flue gas to the atmosphere and provides necessary draft.
    Stack Effect - The difference between the weight of a column of high-temperature gases inside the heater and/or stack and the weight of an equivalent column of external air,usually expressed in inches of water per foot of height.
    Stack Temperature - The temperature of the flue gas as it leaves the convection section,or air preheater directly upstream of the stack.
    Two-Side Fired Tubes - Radiant section tubes which are exposed on both sides to direct radiation from the burners.
