Abstract
A heater includes a radiant section having a wall and a roof, the roof having a longitudinal opening. A radiant heat exchange tube is disposed in the radiant section, and the tube has an inlet and outlet through which a process fluid can be carried respectively into and out of the radiant section. The tube between the inlet and outlet is arranged in generally horizontal tube lengths. A plurality of burners is provided, at least two of the burners being disposed on opposing sides of the tube. A plurality of tube supports is releasably positioned at longitudinal intervals along the tube lengths and define tube seats on which the tube lengths rest. The tube and tube supports are liftable as a unit through the longitudinal opening of the roof of the radiant section.

A heater comprising:
- a radiant section having a wall and a roof, the roof having a longitudinal opening;
- a radiant heat exchange tube disposed in the radiant section, the tube having an inlet and outlet through which a process fluid can be carried respectively into and out of the radiant section, the tube between the inlet and outlet being arranged in generally horizontal tube lengths;
- a plurality of burners, at least two of the burners being disposed on opposing sides of the tube;
- and
- a plurality of tube supports releasably positioned at longitudinal intervals along the tube lengths, the tube supports defining tube seats on which the tube lengths rest,
- the tube and tube supports being liftable as a unit through the longitudinal opening of the roof of the radiant section.
A heater comprising:
- a radiant section having a wall and a roof, the roof having a longitudinal opening;
- a radiant heat exchange tube disposed in the radiant section, the tube having an inlet and outlet through which a process fluid can be carried respectively into and out of the radiant section, the tube between the inlet and outlet being arranged in generally horizontal tube lengths, the tube lengths being substantially parallel and aligned vertically to form a coil panel that is generally aligned with the longitudinal opening of the roof of the radiant section;
- a plurality of burners, at least two of the burners being disposed on opposing sides of the coil panel;
- and
- a plurality of tube supports releasably positioned at longitudinal intervals along the tube lengths, the tube supports comprising generally vertical stanchions and support arms extending from the stanchions, wherein the tube lengths rest on the support arms so that the tube support supports the coil panel,
- the coil panel and tube supports being liftable as a unit through the longitudinal opening of the roof of the radiant section.
