Fired Heater
Technical Studies & Compliance

Remove Doubt. Reveal Risk. Decide with Evidence.

Do you know where your heater stands? We investigate performance, safety margins and technical compliance.

Our independent studies reveal blind spots, test assumptions and turn complex findings into defensible decisions.

Where We Add Value

Critical Decisions Need Clear Evidence.

Uncertainty carries risk. Routine readings and isolated calculations may miss the full picture.



We check the engineering, challenge assumptions and assess the relevant limits. You get clear findings, remaining uncertainties and practical next steps.

Uncertain operating margins

Are firing, heat flux, tube temperature and draft within justified limits?

Design and specification questions

Do equipment selections and vendor claims match the real duty and project requirements?

Integrity and safety concerns

Could overheating, coking or combustion behaviour threaten safe operation?

Independent technical validation

Will the proposed design, revamp or performance claim withstand independent scrutiny?

Our Technical Capabilities

Reveal What Matters. Verify What Counts.

We bring process, thermal and equipment engineering together. Assess performance. Verify operating margins. Examine changes before committing.

Where relevant, we check against API 560, API 530 and project requirements. Every study answers a defined engineering question.

01 | Performance

Process & Thermal Studies

Verify performance, locate the limits and test whether required duty is achievable.

  • Thermal efficiency, absorbed duty and heat balance assessments
  • Combustion, excess air, draft and burner operating reviews
  • Radiant and convection heat-transfer evaluations
  • Pressure drop, fouling and throughput constraint studies
  • Operating envelope and performance verification

02 | Risk & Integrity

Safety & Equipment Assessments

Expose technical threats to safety, equipment integrity and reliable long-term operation.

  • Tube metal temperature, heat flux and tube-life assessments
  • Coking tendency, fouling and local overheating risk
  • Flame length, combustion and furnace pressure considerations
  • Safeguarding, controls and operating-limit reviews
  • Fired-heater technical input to HAZOP and SIL studies

03 | Assurance & Verification

Design Review & Compliance

Challenge design claims, proposed changes and technical submissions with independent engineering.

  • API 560 and API 530 checks, where applicable to the scope
  • Relevant ASME, client and project specification assessments
  • Third-party technical reviews of EPC and OEM designs
  • Design-basis, equipment selection and calculation verification
  • Performance guarantee and revamp proposal evaluations

Why HeaterSIM

Engineering Judgement Behind Every Finding.

Codes, calculations and simulation provide evidence. Their value depends on sound assumptions and expert interpretation.

We see the heater as one system. We explain not only whether a limit is met, but why a condition occurs, what it means and what action is justified.

What You Can Expect

Clear Findings. Defensible Decisions.

01

Transparent engineering evidence

Know what the evidence supports — and what it does not.

02

Prioritised technical findings

See key assumptions, findings and data limitations without having to search through the report.

03

A practical way forward

Prioritise the next step. Separate confirmed concerns from issues needing further investigation.

Our Method

A Clear Path from Question to Answer.

From a focused calculation to a full independent review, we match the depth of analysis to the decision at hand.

01

Define the question

Define the equipment, technical question, criteria and available evidence.

02

Verify the engineering

Check the analysis, assumptions, sensitivity and design margins.

03

Recommend with clarity

Explain what the results mean and what should happen next.

The scope of any code or compliance assessment is defined against the applicable equipment, standard editions, project specifications and available information.
