Products · Boilers & Heat Recovery
To establish the project design basis for “Process Gas Boilers”, confirm “Process-gas and heat-recovery duty” and its inputs: Specify gas composition and flow, inlet/outlet temperatures, contaminants/fouling, allowable pressure drop and steam-generation conditions. 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 Process Gas Boilers concentrates on steam pressure and temperature, circulation, furnace or process-gas duty, feed-water quality, blowdown, pressure-part design, emissions, control range and operating flexibility. 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 Process Gas Boilers is defined from service data, design conditions, and battery limits. For this equipment, Process-gas and heat-recovery duty and Feed and thermal 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 numeric values below describe one refinery FCCU CO-boiler permit case. They are project-specific, not a generic steam-boiler range or a Delham guarantee.
| Parameter | Published value | Reference basis | Applicability / limit |
|---|---|---|---|
| Steam-production capacity | About 125,000 kg/h (125 t/h) | Facility permit description for one CO boiler firing refinery fuel gas and/or FCCU catalyst-regeneration process gas. | One facility/project rating; feed composition, CO load, auxiliary firing and steam conditions are site-specific. |
| Maximum thermal input | 400 GJ/h | Maximum heat input stated in the same facility authorization. | Regulatory permit limit for that unit, not boiler output duty; do not derive a general efficiency from the paired figures. |
| Process-gas service | FCCU catalyst-regeneration gas + refinery fuel gas | Published fuel description for the permitted refinery CO boiler. | CO oxidation, catalyst fines, sulfur/nitrogen species, auxiliary fuel and downstream controls require case-specific design. |
