In hydrogen‑fueled boiler and furnace installations, uncontrolled pressure spikes can lead to catastrophic failure. Our explosion relief door for hydrogen boiler furnace provides a passive, fail‑safe pathway that vents excess pressure while maintaining the integrity of the surrounding equipment. Designed to meet the rigorous demands of petrochemical, power generation, and heavy‑industry users, the door combines high‑temperature alloys with precision‑engineered sealing to protect personnel, plant uptime, and compliance documentation.

The unit is supplied as a fully fabricated panel that integrates directly into standard 150 mm, 200 mm, or 250 mm thick refractory walls. With a quick‑release actuation mechanism, the door opens automatically when the set pressure threshold is reached, then reseals automatically once conditions normalize, eliminating the need for manual intervention.

All dimensions and pressure settings are fully customizable to match project‑specific drawings. Our engineering team works with you to certify the final configuration against the applicable design codes.

The door is manufactured under ISO 9001‑2015 quality management and conforms to the following internationally recognised standards:

• ATEX 2014/34/EU – Equipment for use in explosive atmospheres (Category 1, Group II)
• IEC 60079‑1 & 2 – Electrical equipment protection and safety
• API 650 – Welded tanks for oil storage (where applicable)
• EN 1090‑1 – Structural steel fabrication
• CE marking – Full compliance with EU Machinery Directive

Our in‑house testing laboratory performs hydrostatic, burst, and high‑temperature cycling tests on every production batch. Documentation, including a Certificate of Conformity and a detailed test report, is supplied with each shipment to streamline your project approval process.

Proper integration of the explosion relief door for hydrogen boiler furnace is critical to maintain its protective function. Follow these key steps:

1. Verify that the opening in the furnace wall matches the door’s nominal dimensions plus a 2‑mm clearance for gasket compression.
2. Mount the door frame using high‑temperature‑rated bolts (M12 – M20) torqued to the manufacturer‑specified values.
3. Install the dual‑seal system: a metal‑to‑metal gasket for normal service and an auxiliary silicone‑based seal for emergency venting.
4. Connect the pressure‑actuated pneumatic piston to the plant’s pressure‑transmitter network. Calibration should be performed at 0.5 % of full‑scale pressure.
5. Conduct a functional test by pressurising the furnace to 90 % of the set‑point and observing door actuation and reseal.
6. Document the installation with photos and a signed inspection report; this is required for ATEX certification renewal.

Our field‑service engineers are available for on‑site support during commissioning and can provide a detailed installation manual tailored to your plant layout.

What is the minimum order quantity (MOQ) for a custom‑size explosion relief door?

We accept single‑unit orders for prototypes and pilot projects. For serial production the MOQ is 5 units, which allows us to optimise material cutting patterns and reduce lead time.

Can the pressure‑release setting be adjusted after installation?

Yes. The pneumatic actuator includes an external adjustment screw that can be re‑calibrated in the field without dismantling the door. Adjustments must be logged and re‑validated according to ATEX‑required procedures.

What warranty does the product carry?

All doors are covered by a 24‑month limited warranty against material defects and workmanship when installed per our guidelines. Extended warranty options up to 5 years are available on request.

How do you handle international shipping and customs documentation?

We provide full export paperwork, including CE certificates, test reports, and a commercial invoice that meets INCOTERMS DDP or FCA based on your preference. Our logistics team coordinates with freight forwarders to minimise transit time and duty‑related delays.
