Subcritical Pressure Water Tube Hydrogen Boiler – High‑Efficiency Steam Generation
The subcritical pressure water tube hydrogen boiler is engineered for continuous‑flow hydrogen‑fuelled steam production in petrochemical, refining and large‑scale industrial processes. Its water‑tube design operates below the critical point of water, delivering rapid start‑up, precise temperature control, and superior heat‑transfer efficiency while meeting stringent emissions standards. Designed for modular installation, this boiler integrates seamlessly into existing plant infrastructure, providing reliable steam at pressures up to 1.6 MPa and temperatures up to 350 °C.
Application Scenarios
Our water‑tube hydrogen boiler is the preferred choice for facilities that demand clean‑fuel steam with minimal downtime. Typical deployments include:
- Refinery hydrogen reforming units – providing on‑site steam for catalytic reactors.
- Petrochemical complexes – supporting high‑purity steam for distillation columns.
- Power‑generation combined‑cycle plants – supplementing turbine feed‑water heating.
- Industrial hydrogen‑based heat‑treatment lines – delivering consistent temperature profiles.
Each installation can be customized for duty‑cycle lengths ranging from 8 hours to 24 hours continuous operation, ensuring optimal performance for both peak‑load and base‑load scenarios.

Frequently Asked Questions
What is the minimum order quantity (MOQ) for a subcritical pressure water tube hydrogen boiler?
We accept single‑unit orders for pilot‑scale projects. For commercial‑scale plants, the typical MOQ is one complete boiler system, which may consist of multiple modular sections.
Can the boiler be customized for higher pressure or temperature?
Yes. Our design team can adjust tube material, wall thickness, and control logic to accommodate pressures up to 2 MPa and temperatures up to 400 °C, subject to additional engineering review.
What is the typical lead time from order to delivery?
Standard lead time ranges from 15 to 45 days, depending on configuration complexity and current production schedule. Expedited manufacturing options are available upon request.
What warranty and after‑sales support are provided?
All units ship with a 24‑month comprehensive warranty covering material and workmanship. Our technical service team offers on‑site commissioning, training, and a 24/7 spare‑parts hotline.
