Product Description
Manufactured at our 13,800+ square meter heavy manufacturing complex in Jingjiang, our Catalytic Reforming Heater is a specialized, multi-cell process fired heater-commonly built in a four-in-one shared-casing configuration-engineered to supply interstage reheat energy across multi-reactor Continuous Catalytic Reforming (CCR) and semi-regenerative reforming units. Backed by 26 years of heavy fabrication experience serving refinery leaders like Sinopec and CNPC, we build each Catalytic Reforming Heater with symmetric inverted-U or vertical-U coil circuits designed to minimize hydraulic pressure drop while maintaining tight, uniform temperature control across each reforming reaction stage. By optimizing radiant heat release and integrating high-efficiency convection banks, this industrial-duty Catalytic Reforming Heater delivers thermal efficiencies over 91%, providing refiners and EPC contractors with a robust heating foundation for maximizing high-octane gasoline blending stocks and aromatics yields.
Applications
Continuous Catalytic Reforming (CCR) Units: Providing interstage heating for three or four radial-flow reforming reactors in series to sustain endothermic dehydrogenation reactions.
Fixed-Bed Semi-Regenerative Reforming Plants: Supplying primary feed heating and interstage reheating across multi-reactor reforming loops.
High-Octane Reformate & BTX Production: Heating heavy naphtha feedstocks to maximize aromatic yields (benzene, toluene, xylenes) and high-octane blend components.
Refinery Hydrogen Generation Loops: Providing continuous, high-temperature reaction heat to sustain catalytic dehydrogenation reactions that produce byproduct hydrogen.

FAQ
Q: Why is a four-in-one configuration preferred for catalytic reforming units?
A: Reforming reactions are strongly endothermic and require reheat between successive catalyst beds. A four-in-one furnace houses all four heating stages in a single structure, minimizing plot space, piping heat loss, and capital costs while allowing independent firing control for each stage.
Q: What is the typical fabrication lead time for a four-in-one Catalytic Reforming Heater?
A: Custom fabrication typically requires 4 to 6 months from technical drawing approval and material procurement to factory dispatch. Standard replacement coil sets can be delivered in approximately 3 months.
Q: What warranty coverage do you provide for international deliveries?
A: We provide an 18-month warranty from site arrival or 12 months from commercial operation (whichever comes first), backed by responsive technical engineering support.
Q: What payment terms and currencies do you support for international contracts?
A: We support EXW and FOB shipping terms. Our standard commercial milestones are 30% advance deposit, 40% manufacturing milestone payment, and 30% balance prior to factory dispatch, payable in USD, EUR, or RMB.
