Boilers Spare Parts — Marine Auxiliary & Exhaust Gas Catalogue

PartYard is a specialist supplier of spare parts for marine and industrial boilers, serving commercial vessel operators, shipyards, and offshore facilities across Europe and internationally. Our catalogue covers both auxiliary boilers and exhaust gas boilers, with genuine and OEM-equivalent components for the most widely used types in the global fleet. Whether you operate a small coastal vessel or a large ocean-going ship, PartYard provides fast sourcing and competitive pricing for all marine boilers spare parts.

Our team has extensive experience supporting maintenance and overhaul operations for vessel operators worldwide. We supply components for scheduled maintenance intervals, emergency repairs, and complete overhaul programmes, ensuring your boilers remain operational and certified throughout their service life. Every order is handled by a dedicated technical specialist who understands the requirements of marine steam systems and the urgency of keeping them running reliably at sea.

Auxiliary Boilers — Spare Parts & Overhaul Kits

Auxiliary boilers provide steam and hot water for essential ship services including fuel heating, accommodation heating, galley steam, and cargo heating. Reliable operation is critical to vessel safety and comfort, particularly in cold climates and for vessels carrying heavy fuel oil that requires continuous heating. PartYard stocks a comprehensive range of spare parts for auxiliary systems used across the global merchant fleet.

Our auxiliary catalogue includes components for ESH-series and other widely used types. We supply burner assemblies, nozzles, ignition components, flame detectors, pressure gauges, safety valves, water level gauges, feed water pumps, circulation pumps, and gasket sets for auxiliary boilers of all sizes. For custom-designed units built to specific vessel requirements, our team can source components based on technical drawings or worn part samples.

Common series supported include the ESH 2.5 and ESH 4.0, along with custom-design variants. Our advisors identify the correct components based on the manufacturer, model reference, serial number, and maintenance scope required. Complete overhaul kits are also available to simplify procurement and reduce lead time for planned maintenance.

Exhaust Gas Boilers — Waste Heat Recovery Parts

Exhaust gas boilers use thermal energy from main engine exhaust to generate steam, reducing fuel consumption and improving vessel efficiency. These units are a key component of modern energy-efficient designs and require reliable parts supply to maintain performance and classification compliance. PartYard supports operators with spare parts for exhaust gas systems across all major types.

Our exhaust gas catalogue includes components for AKS-series units, including the AKS 2.0-16/16×16 and AKS 2.2-24 models. Key components available include exhaust gas tubes, tube bundles, fin tubes, headers, shell sections, inspection doors, soot blowers, drain valves, safety valves, pressure gauges, and sealing sets. Subject to fouling and corrosion from exhaust gases, these systems require regular inspection and cleaning — PartYard supplies all consumable and replacement items needed for each service interval.

Marine Boilers Maintenance — Scheduled Service Parts

Effective preventive maintenance is essential for reliable operation of all marine boilers. PartYard supports maintenance programmes with overhaul kits, consumable parts bundles, and individual replacement components for both auxiliary and exhaust gas systems. Our kits match the manufacturer’s recommended service intervals and classification society survey requirements.

Common items available include burner service kits, ignition electrode sets, flame sensor elements, safety valve overhaul kits, level gauge glass sets, gasket kits, and complete pump overhaul sets. We supply these items individually or as pre-assembled service kits to simplify ordering for planned work in port. For emergency breakdowns, PartYard offers priority sourcing and express delivery for critical components to any port worldwide.

Classification & Certification for Marine Boilers

All marine boilers installed on commercial vessels must comply with the requirements of the applicable classification society, such as Lloyd’s Register, Bureau Veritas, DNV, or ClassNK. Classification societies specify the design standards, material grades, test pressures, and inspection intervals for pressure vessels including auxiliary and exhaust gas systems. PartYard supplies spare parts that meet the material and dimensional specifications required to maintain classification compliance.

When supplying safety-critical components such as safety valves, pressure gauges, and structural elements for marine boilers, we can provide material certificates and test documentation on request. Our team is experienced in coordinating with classification society surveyors and can advise on the documentation requirements for parts used in pressure system repairs that require survey approval. Maintaining proper certification records for your vessel’s steam and heat generation systems is essential for insurance compliance and port state control inspections.

For operators requiring certified spare parts for their boiler systems, PartYard can source components with full material traceability, manufacturer’s test certificates, and conformity declarations as required by the applicable class rules. Contact our technical team to discuss documentation requirements for your specific maintenance scope and classification society requirements.
