Abstract
Processes and apparatuses for heating a process fluid. The process fluid flow through a convection section and then a radiant section. The radiant section produces heat and flue gas from the combustion of the fuel. The flue gases flow to the convection section to provide the heat in the convection section. The conduits in the convection section are straight. All of the fluid that passes through the convection section also passes through the radiant section.
Claims20
An apparatus for heating a process fluid, the apparatus comprising:
- a radiant section having one or more burners configured to provide heat and flue gas;
- a convection section disposed adjacent the radiant section, the convection section configured to receive the flue gas from the radiant section;
- a convection conduit passing through the convection section and configured to receive a process fluid and transfer heat to the process fluid;
- and,
- a radiant conduit passing through the radiant section and configured to receive the process fluid and transfer heat to the process fluid,
- wherein the convection conduit and the radiant conduit are arranged in series such that all of the process fluid passing through the convection conduit passes through the radiant conduit.
3 more elements
A method for heating a process fluid, the method comprising:
- combusting fuel in a radiant section of an apparatus to produce heat and flue gas;
- passing a process fluid through a convection section to heat the process fluid, the convection section receiving the flue gas from the radiant section;
- passing the process fluid through the radiant section to heat the process fluid, wherein the process fluid that passes through the radiant section has passed through the convection section.
