Why Are Your Kilns Underperforming? Here’s How HTAC Technology Boosts Temperature by 15°C

In the high-temperature industries—like ceramics, steel, and glass production—inefficient kiln operation isn’t just a cost issue—it’s a sustainability crisis. Many manufacturers still rely on outdated combustion systems that waste up to 40% of fuel energy, leading to poor heat transfer, inconsistent product quality, and excessive emissions.

The Root Cause: Inefficient Air Preheating

Traditional kilns use direct flame combustion without proper air preheating. This results in low flame temperatures (< 1200°C), incomplete fuel burn, and significant thermal losses through exhaust gases. The problem? Up to 70% of heat is lost before it even reaches the work zone.

That’s where Regenerative High-Temperature Air Combustion (HTAC) comes in—a breakthrough developed by Zhengzhou Rongsheng Refractory Material Co., Ltd. Their honeycomb ceramic regenerator system transforms how industrial furnaces operate.

How HTAC Works: Simpler Than You Think

HTAC uses a two-phase cycle:

• Phase 1 (Heat Storage): Hot flue gas passes through the honeycomb ceramic blocks, heating them to over 1100°C.
• Phase 2 (Air Heating): Cold air enters the same block, absorbing stored heat—reaching 900–1000°C before entering the furnace.

This means the flame temperature jumps from ~1100°C to over 1250°C—a real-world increase of +15°C or more. No wonder one client in Mexico saw their furnace output rise by 18% after installation.

Real Results: Fuel Savings & Emission Reduction

These aren’t hypothetical numbers—they’re from actual installations in Germany, China, and Brazil. One German ceramics plant reduced annual fuel costs by €48,000 while cutting CO₂ emissions by 210 tons/year. That’s not just efficiency—it’s compliance with EU Green Deal standards.

Global Certifications = Trust + Compliance

Rongsheng’s HTAC system has passed international certifications including ISO 14001 (Environmental Management) and CE Marking for European markets. These aren't just badges—they mean your facility can meet stricter environmental regulations now, not later.

“We installed this system in our glass melting furnace last year. Within six months, we achieved a 15% reduction in natural gas usage—and our customers noticed better surface finish consistency.” — Juan Martinez, Plant Manager, Grupo Vidrio Mexicano

If you're in manufacturing, construction materials, or metal processing—you’re likely wasting money and resources. Don’t wait for another audit or regulatory warning. Start optimizing your kiln today with proven HTAC technology.
