Pre-RH Vacuum Furnace Regenerator

Core Working Principle: 
Our regenerative burner system uses paired "regenerators" as the core heat exchange medium. Its working cycle is as follows:
Regeneration Cycle: High-temperature flue gas (typically >1100°C) flows through the regenerator (usually ceramic spheres or honeycomb) on one side of the burner under the action of an induced draft fan, transferring most of its heat to the regenerator. The flue gas temperature is reduced to an extremely low level (typically <150°C) before being discharged.
Reversing and Heat Release Cycle: The airflow direction is switched in a very short time (tens of seconds) using an advanced reversing valve. Combustion air enters from the other side, flowing counter-currently through the preheated heat storage medium, rapidly absorbing its stored heat and preheating to near furnace temperature (preheating temperature can reach over 1000°C).
High-efficiency combustion: This high-temperature combustion air mixes and combusts with fuel at the burner nozzle, forming a high-speed, high-temperature flame that is injected into the furnace to heat the workpiece.
Through this periodic alternating heat storage and release, the system achieves maximum recovery of waste heat from the flue gas, maximizing thermal efficiency.
Core Product Advantages:
1. Improved thermal efficiency and reduced fuel consumption
Flue gas waste heat recovery rate >90%: Maximum heat recovery through the heat storage medium; combustion air preheating temperature can reach over 1000°C.
Exhaust gas temperature reduced to below 150°C: Achieves highly efficient energy utilization, directly reducing fuel consumption per unit of product.
2. Achieve High Temperature and High Uniformity Process Requirements
Supports furnace temperature ≥1300°C: High-temperature preheated air ensures stable and efficient fuel combustion in vacuum or low-oxygen environments.
Furnace temperature uniformity within ±3°C (according to AMS2750 standard): High-speed airflow enhances convective heat transfer, helping to reduce the temperature gradient within the furnace.
3. Reduce Nitrogen Oxide Emissions
Utilizes high-temperature, low-oxygen combustion technology: Combustion zone characteristics and staged combustion principles effectively suppress the formation of thermal NOx.
4. Improve System Operating Economy and Durability
Reduces downstream component heat load: Low-temperature flue gas emissions reduce thermal stress and material requirements on downstream piping and dust removal equipment.
Key components use high-temperature resistant and thermal shock resistant materials: Specialized material selection for core units such as regenerators and reversing valves aims to extend system maintenance cycles and service life.
