Refractory Repair Mortar for Hydrogen Boiler Furnace
Product Overview
Our refractory repair mortar for hydrogen boiler furnace is engineered to restore high‑temperature linings in hydrogen‑fuelled boiler systems. Designed for rapid set‑up and long‑term thermal stability, the mortar tolerates temperatures up to 1800 °C while maintaining structural integrity under cyclic heating. The formulation blends high‑purity alumina, calcium aluminate cement, and proprietary hydrogen‑compatible additives, delivering a repair solution that meets the stringent demands of modern low‑carbon power plants.
Technical Specifications
| Parameter | Typical Range | Units |
|---|---|---|
| Maximum Service Temperature | 1500‑1800 | °C |
| Compressive Strength (24 h) | 35‑45 | MPa |
| Setting Time (initial) | 20‑30 | minutes |
| Thermal Shock Resistance | ≥ 150 °C/min | ΔT |
| Hydrogen Compatibility Rating | Class A | — |
All parameters are customizable per order. Adjust the alumina content, bonding additives, or grain‑size distribution to match specific furnace geometry, duty cycle, or retrofit schedule.
Competitive Advantages
- Hydrogen‑Resistant Chemistry – The binder system resists embrittlement caused by hydrogen permeation, extending service life beyond conventional alumina mortars.
- Rapid Re‑Establishment of Insulation – Initial set in less than 30 minutes, allowing boiler restart within a typical 4‑hour maintenance window.
- Low Shrinkage – < 0.5 % volumetric change after curing, preventing cracking on hot‑cold cycles.
- Scalable Production – Available in bulk 25 kg bags to 5‑ton silos, with OEM/ODM support for proprietary formulations.
- Compliance & Traceability – Certified to ISO 9001, ISO 14001, and meets IEC 61784‑2 for hydrogen service environments.
Application Scenarios
The mortar is suitable for a range of hydrogen‑fired equipment, including:
- Primary furnace walls of 500 MW hydrogen boiler units where retrofit downtime must stay under 6 hours.
- Secondary combustion chambers exposed to intermittent high‑temperature spikes during load‑following operation.
- Refractory bricks and castables that have suffered micro‑cracking due to hydrogen‑induced oxidation.
- Pilot‑scale test rigs that demand quick turnaround and reproducible repair batches.
FAQ
What is the minimum order quantity (MOQ) for custom grades?
Standard packaging starts at 25 kg bags with an MOQ of 5 bags. For bespoke formulations, the MOQ is 500 kg, allowing us to fine‑tune alumina content and additive packages.
Can the mortar be mixed on‑site, and what equipment is required?
Yes. A conventional high‑speed mortar mixer (≥ 150 rpm) with a capacity of 30 kg is sufficient. The powder is supplied dry; add clean de‑ionised water according to the batch‑specific water‑to‑powder ratio (typically 0.12‑0.15 kg/kg).
What is the typical lead time from order confirmation to shipment?
Standard grades ship within 15‑25 days. Custom grades require 30‑45 days, depending on formulation complexity and required testing.
Is there a warranty or performance guarantee?
We provide a 12‑month performance warranty against premature degradation under normal operating conditions, supported by third‑party lab verification.
