Ceramic Fiber Lining for High‑Temp Hydrogen Boilers
Application Scenarios
Hydrogen‑fueled power plants demand boiler sections that can withstand continuous temperatures above 900 °C while maintaining structural integrity in a highly oxidative environment. Our ceramic fiber lining is engineered for precisely these conditions, providing a protective barrier inside high‑temp hydrogen boilers used for electricity generation, industrial heat recovery, and large‑scale chemical synthesis. The material’s low thermal conductivity reduces heat loss, improving overall plant efficiency and supporting stricter emissions targets. Whether the boiler operates in a utility‑scale combined‑cycle plant or a dedicated hydrogen‑only facility, the lining adapts to the thermal cycling and pressure loads typical of modern energy infrastructure.
Product Overview
Our ceramic fiber lining is a flexible, woven fabric composed of high‑purity alumina‑silica fibers bonded with a refractory matrix. The product is supplied in rolls or pre‑cut blankets, allowing seamless integration into boiler tubes, fireboxes, and convection sections. The non‑metallic nature eliminates galvanic corrosion risks, while the high silica content provides resistance to hydrogen embrittlement. The lining can be trimmed on‑site to match custom dimensions, making it ideal for OEMs and retrofit projects alike. All grades meet the temperature and pressure specifications outlined in ASME Boiler & Pressure Vessel Code Section I.

All dimensions, fiber density, and surface treatments can be tailored to match the exact geometry of your boiler chamber, ensuring a perfect fit and eliminating the need for secondary sealing compounds.
Competitive Advantages
- Thermal Efficiency: Low conductivity reduces heat‑transfer losses by up to 15 % compared with conventional metallic claddings.
- Longevity: Resistant to oxidation, thermal shock, and hydrogen‑induced cracking, extending service intervals beyond 5 years under continuous operation.
- Weight Reduction: Up to 70 % lighter than cast refractory bricks, decreasing overall boiler dead weight and simplifying handling.
- Regulatory Compliance: Meets ISO 9001 quality management, ISO 14001 environmental, and ASME Section I pressure‑vessel standards.
- Scalable Supply: Production capacity supports orders from 1 m² up to multi‑thousand‑square‑meter projects without compromising batch consistency.
Frequently Asked Questions
What is the minimum order quantity (MOQ) for custom‑cut blankets?
Our standard MOQ is 20 m² of fabric, but we can accommodate smaller batches (as low as 5 m²) for prototype or pilot‑plant installations, subject to a setup surcharge.
Can the lining be modified for specific pressure ratings?
Yes. By adjusting fiber weave density and adding a high‑temperature binder, we can certify the product for pressure classes up to 2 MPa (30 psi) while retaining its thermal performance.
What lead time should I expect for a 500 m² order?
Typical lead time ranges from 15 to 45 days, depending on the final dimensions and any special surface treatments required.
Does the ceramic fiber lining for high temp hydrogen boiler carry a warranty?
All shipments include a 12‑month limited warranty against material defects when installed according to our technical guidelines.
