Frequently Asked Questions
Gas & Oil Boiler Technical FAQ
Common questions from project managers, procurement teams, and engineers considering gas and oil-fired boilers for their facilities.
How is boiler efficiency evaluated for a gas or oil-fired project?
Boiler efficiency is project-specific. It depends on fuel composition, load profile, steam or hot-water duty, burner selection, excess air, feedwater temperature, stack temperature and any heat-recovery equipment.
- • Economizer: Can be reviewed for suitable flue-gas heat recovery
- • Burner control: Turndown and excess-air control depend on the selected burner package
- • Condensing service: Requires review of return-water temperature, fuel and corrosion considerations
- • Performance basis: Efficiency method and guarantee values, if required, are agreed in the technical specification
ORL can review the available operating data and identify the information needed for a project-specific performance calculation.
Which fuels can be reviewed, and can a boiler operate on dual fuel?
Natural gas, LPG, light diesel, heavy fuel oil and dual-fuel configurations can be reviewed. Other gaseous or liquid fuels require a fuel-analysis and burner-suitability review before confirmation.
Fuel Data:
- • Gas composition, pressure and heating value
- • Liquid-fuel viscosity, sulfur and heating value
- • Expected fuel variation and backup-fuel requirement
System Review:
- • Burner and fuel-train selection
- • Control and safety interlocks
- • Atomization or preheating requirements where applicable
Conversion of an existing boiler between fuels should only be confirmed after review of the burner, fuel train, furnace conditions, controls and applicable safety requirements.
How are manufacturing and delivery schedules determined?
Schedule depends on engineering scope, drawing approval, material availability, burner and accessory procurement, inspection hold points, certification requirements, module size and shipping route.
- • Engineering: Finalized after design basis and document-submittal requirements are agreed
- • Manufacturing: Planned against material, welding, inspection and testing activities
- • Shipping: Packing and transport method depend on equipment dimensions, destination and agreed Incoterms
A project-specific schedule is confirmed during the quotation and contract stage rather than as a fixed website lead time.
Which design codes and certification requirements can be reviewed?
ORL holds ASME S & U capabilities and operates certified quality systems. The applicable boiler code, conformity-assessment route and local registration requirements are confirmed for each project.
- • ASME: Scope reviewed according to the required boiler or pressure-equipment code
- • EN requirements: Applicable design and manufacturing requirements reviewed by project
- • GB: Chinese boiler and pressure-equipment requirements where applicable
- • Third-party inspection: Can be coordinated when specified in the ITP or contract
CE/PED or other jurisdiction-specific conformity should not be assumed automatically; it is confirmed only when included in the agreed project scope.
Can installation, commissioning and operator support be included?
Site services can be reviewed according to project location, equipment boundary, local regulations and the agreed responsibility matrix.
- • Installation or erection supervision when included in the contract
- • Commissioning assistance and burner coordination where applicable
- • Operator or maintenance guidance according to the agreed service scope
- • Spare-parts recommendations based on the supplied equipment
Site duration and service availability are project-specific and are confirmed in the commercial proposal.
How is warranty coverage defined?
Warranty period, start date, covered equipment, exclusions and claim procedures are defined in the applicable quotation and contract. They can vary by project, supplied component and responsibility boundary.
- • Manufacturing-defect coverage is defined contractually
- • Burner, controls and bought-out equipment may follow the agreed supplier or project warranty terms
- • Consumables, normal wear and damage caused by operating conditions are addressed in the contract terms
- • Recommended operation, water-quality and maintenance requirements should be followed for warranty support
