Part 2. Energy-Saving Heat Storage Products
REBO’s energy-saving heat storage line centers on ceramic honeycomb regenerators in a full range of materials. These regenerators are key heat exchange parts for industrial furnaces and high-temperature systems. They have a huge surface area and great heat storage capacity. and they absorb waste heat from hot flue gas. They then preheat combustion air or gas in reverse very quickly. This recovers over 90% of heat. It greatly cuts fuel use and carbon emissions. The result is lower operating costs and better energy efficiency for global customers.

How to Select Acid Proof Bricks Lining?
Acid proof brick linings include three main products. Select the suitable product through the following steps:
- Check the Medium (Determine Material);
- Evaluate Temperature & Thermal Shock (Determine Processing);
- Assess Load & Impact (Determine Thickness & Hardness);
- Examine Geometry & Structure (Determine Shape);
- Match the Mortar (Ensure System Locking).

How to Select Acid Resistant Mortar?
Choosing the right acid resistant mortar is the key to a successful anti-corrosion lining project. A good choice brings strong protection and long service life. To choose the right acid resistant mortar, follow these 5 core steps:
- Check acid-base media and chemical compatibility (determine the anti-corrosion binder).
- Evaluate working temperature and thermal shock (determine the temperature resistance grade).
- Consider mechanical stress and vibration impact (determine toughness and bonding strength).
- Match the lining block material (system thermal expansion matching).
- Consider anti-permeation requirements and construction environment (determine density and project schedule).
| Comparison Feature | Furan Resin Mortar | KP1 Silicate Acid-Proof Mortar |

| Impermeability | Ultra-high (Dense cured structure) | Fair (Porous; requires acid treatment or membrane) |
| Relative Cost | Moderate | Low/Economic |
How to Select Heat Storage Products?
In industrial waste heat recovery and high-temperature furnace systems, choosing the right ceramic honeycomb regenerator requires comprehensive matching based on the following conditions. Precise material and structure selection ensures long service life. It also maximizes heat recovery efficiency.
- Select material by working temperature.
- Prioritize thermal shock resistance according to heating/cooling frequency.
- Determine slag and corrosion resistance by evaluating dust content and chemical aggressiveness.
- Match hole type and pore size by heat exchange and pressure drop needs.
Al₂O₃ 30–35% · ≤1200°C
Best thermal shock resistance. Low temperature & slag resistance.
Al₂O₃ 45–75% · 1200–1300°C
Economical transition material. High cost-effectiveness.
Al₂O₃ 60–72% · 1300–1350°C
Standard material for industrial furnaces. Balanced performance.
Al₂O₃ ≥90% · 1600–1700°C
Mohs 9. Extreme hardness. Resists strong acids/alkalis & gas erosion.
