To establish the project design basis for “Reaction Furnaces”, confirm “Reactive feed and reaction-zone conditions” and its inputs: Define feed composition/flow, pressure/temperature and thermal profile, reaction conditions, pressure drop and process-based material/refractory basis. Final values, supply limits and acceptance criteria are recorded in approved engineering documents; no generic capacity or catalogue guarantee is assumed.
From project definition to delivery
Engineering of Reaction Furnaces concentrates on absorbed duty, allowable tube heat flux, burner arrangement, draft, combustion control, tube metallurgy, refractory, emissions and safe light-off or shutdown logic. The selected configuration is verified against normal, minimum, start-up, shutdown and credible upset cases, then checked for operability, maintainability, energy use, process safety and site interfaces before the design is frozen.
The design basis for Reaction Furnaces is defined from service data, design conditions, and battery limits. For this equipment, Reactive feed and reaction-zone conditions and Fuel and process conditions must be completed in the datasheet and design documents; performance values and guarantees are set only after the project basis is approved.
Materials, corrosion allowance, sour-service requirements, piping classes, nozzle design, insulation, coating, supports and maintenance access are coordinated with the actual process conditions and project code hierarchy.
Control philosophy, alarms and trips, cause-and-effect logic, interlocks, start-up and shutdown sequences, safe depressurization and operator access are developed consistently from the P&IDs through functional testing.
Battery limits, tie-in points, structural loads, cabling, instrumentation, drains, vents, access routes, lifting envelopes and shipping constraints are controlled through coordinated models and interface drawings.
From project definition to delivery
Proposal quality depends on complete input data and an explicit acceptance basis. The following lists provide a practical starting point and are completed during technical clarification.
Technical Datasheet
These values describe one published sulfur-recovery (Claus) reaction-furnace offering. They are not universal limits for every reaction furnace; process licensor requirements and acid-gas composition govern.
| Parameter | Published value | Reference basis | Applicability / limit |
|---|---|---|---|
| Published minimum furnace temperature | 982°C (1,800°F) | Minimum reaction-furnace temperature stated for one sulfur-recovery burner/furnace family. | Claus-service example only; verify ammonia/hydrocarbon destruction, refractory hot-face conditions, residence time and licensor criteria. |
| Published acid-gas H₂S composition | 35–90% H₂S | Feed-composition span published for the cited Claus main-burner/reaction-furnace offering. | Confirm the full gas analysis, contaminants, heating value, acid-gas pressure and operating cases; this is not a universal feed limit. |
| Published turndown ceiling | Up to 10:1 | Published maximum turndown; source qualifies it as dependent on acid-gas pressure. | Confirm stable burner operation, control authority and composition at minimum flow; do not treat as a guaranteed plant turndown. |
