Abstract
Processes and apparatuses for heating a process fluid with a heater having a burner. Fuel is passed to the burner and combusts to product heat. An inert gas stream is provided to the burner, either upstream or downstream or both, of the burner. The flow of the inert gas stream is controlled based on a composition of the fuel, with more inert gas being passed downstream of the burner to when the amount of hydrogen in the fuel is increased.
Claims20
A process for heating a process fluid stream in a heater, the process comprising:
- determining a composition of a fuel passed to a burner of a heater, wherein the fuel is combusted to produce heat, and wherein the composition of the fuel is a hydrogen fuel, a hydrocarbon fuel, or a mixture of hydrogen and hydrocarbon;
- determining a mass flow rate for the heater based on the composition of the fuel;
- and,
- adjusting a flow of an inert gas stream to the heater based on the mass flow rate.
A process for heating a process fluid stream in a heater, the process comprising:
- passing a fuel stream to a burner of a heater, wherein the heater comprises a radiant section with at least one conduit with a process fluid stream;
- combusting fuel from the fuel stream in a combustion zone to produce a flame and heat;
- passing an inert gas into the combustion zone, downstream of the flame to provide a heated, mass enriched flue gas;
- and,
- transferring heat from the heated, mass enriched flue gas to the process fluid stream in the radiant section.
A device for heating process fluid stream comprising:
- a heater with a burner in a radiant section, the radiant section comprising at least one conduit with a process fluid stream;
- a burner configured to receive a fuel stream and combust the fuel stream in a combustion zone to produce a flame and heat;
- a line configured to pass an inert gas into the combustion zone, downstream of the flame to provide a heated, mass enriched flue gas.
