Step Type Furnace Regenerative Heat Recovery System - Advanced Energy-Saving Solution for Industrial Heating
JIANGSU YINUO THERMAL ENERGY TECHNOLOGY CO., LTD supplies Step Type Furnace Regenerative Heat Recovery systems. Steel reheating and forging are where these units work hardest. Thermal efficiency decides the result there. Each unit is built around regenerative combustion technology. Heat recovery rates reach 80-90%. Fuel use falls by more than 30%. Our plant covers 20,000㎡, fixed assets total 80 million yuan, and the team includes 100+ experts. Every heating system is delivered complete, and unit heat consumption is ≤1.05 GJ/t. Oxidation loss rates stay below 0.9%. That gives industrial operations reliable performance.
What Makes Our Regenerative Heat Recovery Technology Strong?
Our product solution solves the most important issues in the energy-intensive business of steel heating. The device uses paired regenerators packed with high-alumina ceramic honeycomb media to absorb waste heat from exhaust gases and preheat combustion air to temperatures above 1000°C.
This method makes flameless combustion possible. Against traditional burners, NOx emissions can fall by as much as 50 percent. Exhaust temperatures remain under 150° C. Heat that would normally be lost is captured instead.
Inside your furnace chamber, temperature stays within 5°C deviance. Billet quality improves when heat is that even. Scale formation drops by 15-20%. Product yield rises. Less raw material ends up as waste.

Core Advantages for Your Operations
Strong Energy Efficiency: Our regenerative system cuts fuel use by 30% or more. Running the plant costs you a lot less as a result. Low-calorific gases burn well in this technology too, blast furnace gas included. Costly enrichment is not needed for that.
Better Product Quality: Heating stays uniform, so billets come out without surface scratches or black oxidise markings. Inside the furnace chamber, Step Type Furnace Regenerative Heat Recovery holds the temperature accurately. Final products then keep constant metallurgical qualities.
Environmental Compliance: Flameless combustion lowers NOx by its very nature. You can meet strict emission rules without extra treatment equipment. Exhaust temperatures stay below 150°C, which keeps thermal pollution to a minimum.
Flexibility in Operation: Different production runs need different setups. That is why the system adapts. Electrode removal can be adjusted, and position control runs on its own. Billet sizes and materials vary a lot. The walking beam design has no mechanical limits to get in the way.
Extended Equipment Life: Thermal shock does not bother ceramic regenerators. They hold up. You can count on them. On some units, built-in air purging keeps particulate buildup away. The result is years of dependable service and very little upkeep.
Step Type Furnace Regenerative Heat Recovery for Industrial Applications
Steel Rolling Operations: Large-scale billet and slab reheating works well with this system. It uses pure blast furnace gas efficiently. Costly coke oven gas enrichment is no longer needed. Heating performance stays strong for continuous production lines.
Heavy Forging Facilities: Step Type Furnace Regenerative Heat Recovery is a must for high-alloy steel ingot work. Here, exact ramp rates in temperature stop thermal cracks from forming inside the metal. Tough forging schedules for complex parts also depend on how steady the system's heat stays.
Heat Treatment Lines: Suppliers in automotive and aerospace meet AMS2750F pyrometry rules with our system. High thermal inertia does the work, and recovery after door cycles is fast. That keeps heat treatment results even in high-throughput plants.
FAQ
Q: How does the system prevent regenerator clogging from furnace dust?
A: We incorporate large-cell honeycomb structures combined with integrated high-pressure air-purging systems that actively prevent particulate accumulation and maintain optimal flow characteristics throughout operation.
Q: What return on investment can we expect?
A: On typical fuel costs, most facilities get their money back in 12-24 months. Two things drive that. Fuel consumption falls by 30%+, and better product quality means fewer rejects.
Q: Can it work with the automation systems we already have?
A: Absolutely. Our regenerative controllers feature standard Modbus/TCP and Profibus interfaces that seamlessly integrate with your existing DCS or Level 2 automation systems without requiring major control infrastructure changes.
Q: How frequently requires the ceramic media replacement?
A: With proper filtration and temperature management, reliable ceramic honeycombs typically deliver 3-5 years of reliable service before inspection or partial replacement becomes necessary.
Q: Does regenerative heating increase oxidation scale formation?
A: Contrary to expectations, it actually decreases scale formation by 15-20%. The uniform temperature field and precise atmosphere control create optimal conditions that minimize oxidation losses.
