Describe the changed fuel accurately
Provide the proposed fuel information and available supply conditions rather than only a commercial name. Ask the responsible fuel supplier and project team to confirm relevant properties and variability. A burner selected for an earlier fuel cannot be assumed suitable for every replacement source. Mark unavailable information clearly so the boiler integrator can identify what remains necessary before giving an accepted response.
Review the complete combustion arrangement
Ask whether the changed fuel affects the burner, fuel train, conditioning, controls or other supporting equipment. A dual-fuel description is not a blanket approval for arbitrary compositions or supply conditions. The relevant provider should identify the actual installed components and restrictions. Keep changes to useful thermal duty connected to the complete boiler package rather than review the burner catalogue rating in isolation.
Revisit the external supply boundary
A new site source may require different purchaser-supplied equipment or interfaces. Request an updated responsibility drawing and clarify the accepted connection conditions. Receiving a fuel at the site does not establish that it is suitable at the burner boundary. Assign any further conditioning and integration review to the responsible providers without deriving a universal field modification or operating sequence from a purchase discussion.
Identify affected verification and documents
Ask which previous selections, records and proposed tests remain applicable after the change. Relevant destination or emissions evidence may depend on the actual configuration and accepted fuel basis. Do not assume a document for another arrangement covers the revised package. Keep the provider’s response specific about what needs updating, what can be retained and which conditions still require project review before acceptance.
Price the change transparently
Separate replacement equipment, additional engineering, verification, service items and schedule effects. A lower fuel unit price does not establish a lower complete heating cost if the changed arrangement has other requirements. Obtain supported consumption and useful-output information for the revised duty. Keep original and revised offers visible so the purchaser can decide whether the change is justified on the same accepted application basis.
Freeze the revised configuration
Once the proposed change is accepted, update the equipment list, fuel requirements and relevant operating information. Identify the record that controls future replenishment and service decisions. A verbal approval or an amended fuel label is not enough to define the final package. Actual commissioning, adjustment and operation must remain under qualified personnel and the approved equipment-specific and project arrangements.
Avoid assuming changeover capability
A boiler truck may be offered with particular fuel options, but the order needs to identify the option actually supplied and the conditions it supports. Request any changeover behavior as an express design and verification scope. Do not infer automatic transition, uninterrupted heating or universal gas suitability from the term dual fuel. Keep the accepted limitations with the final equipment and support records.
Put these items side by side in the bid review
| Purchase item | Question to resolve | Evidence to request |
|---|---|---|
| Change | What fuel basis is different? | Reviewed original and proposed specifications |
| Effect | Which components and duty cases change? | Integrator impact response |
| Acceptance | Which evidence needs revision? | Updated documents and verification scope |
Suggested wording for the quotation request
Assess the proposed site fuel change for the ordered oilfield boiler truck. Identify affected components, external conditioning, useful-duty restrictions and required evidence. State changes to price, schedule, service and documentation. Confirm only the expressly supported revised arrangement, with remaining purchaser inputs and approval conditions visible before shipment or site use.
Evaluate the oilfield boiler truck as an identified mobile thermal package for the accepted medium, receiving conditions and working schedule. Keep useful output, simultaneous pressure and flow, fuel, water, auxiliaries and environment on one agreed basis. The selected boiler architecture, controls, instruments and chassis must match the actual offer. External distribution, receiving equipment and site acceptance require explicit responsibility boundaries. Component maxima or exterior photographs do not establish the complete delivered duty, universal compliance or a field-treatment result. Actual operation and maintenance require competent personnel, configuration-specific manufacturer information and approved project procedures.
For the wider equipment scope, consult the Mobile Oilfield Boiler Truck: Compatibility Guide. Use the RFQ checklist to collect the supporting documents before requesting a configuration-specific quotation.
Buyer questions
Does a dual-fuel label approve any available site gas?
No. The actual composition, supply conditions and offered combustion arrangement need provider review.
Can a fuel substitution leave prior evidence unchanged?
Possibly, but the responsible provider must identify what remains applicable and what needs revision for the actual change.
Background and supplier contact
ASME boiler and pressure-vessel code background offers related background, not certification of the equipment in a quotation. Applicability must be checked for the project and destination.
