Products · Fired Equipment & Process Heaters
To establish the project design basis for “Fired Heaters”, confirm “Duty and load range” and its inputs: Provide minimum/normal/rated/maximum duty, process fluid/flow, inlet/outlet conditions and turndown cases. 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 Fired Heaters 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 Fired Heaters is defined from service data, design conditions, and battery limits. For this equipment, Duty and load range 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
The figures are published capabilities for one API-style direct-fired heater family. They are market references—not universal standard limits, Delham ratings, or project guarantees.
| Parameter | Published value | Reference basis | Applicability / limit |
|---|---|---|---|
| Single-heater absorbed duty | 1 to >100 MMBtu/h (about 0.29 to >29.3 MW) | Published range for one direct-fired heater product family. | The upper end depends on configuration, fuel, process duty and site conditions; do not extrapolate to other heater types. |
| Net thermal efficiency | 85% standard; capability up to 90% | Published standard and optional performance for the same product family. | Verify the efficiency definition, fuel, excess oxygen, process outlet conditions and test boundary before comparison or guarantee. |
| Application of API 560 | General refinery fired-heater scope only, when selected | The linked API 560 reference is limited to its stated general refinery-heater scope. | An API-style product description is not proof of certification or blanket applicability to reformer, pyrolysis or other furnace designs. |
