Gas-Fired, for Melting and Holding
Heat exchanger in the exhaust gas duct
The fuel-heated crucible furnaces in the TBR product line fitted with the side exhaust gas discharge provide for
optimum energy utilization combined with highest quality melt. Fitted with a burner system including heat-recovery
system using a recuperative burner, the energy efficiency of ordinary fuel-heated melting furnaces is significantly
improved.
Depending on utilization the hot exhaust gases from the crucible furnace are guided through a heat exchanger in
order to preheat the combustion air for the burner. The system provides for energy savings of up to 25 % compared
to ordinary fuel-heated furnaces with side exhaust gas discharge. The higher purchase costs are amortized within a
short time.
Emergency outlet for safe melt discharge
in case of crucible break
- Tmax 1100 °C for aluminum and zinc alloys
- Two-stage output control: High load for melting operation, low load for holding operation with automatic switching between both modes
- Modern burner system with optimized flame guide: High efficiency provided by over-pressure operation to keep out entrained air
- Heat exchanger in the exhaust gas duct to preheat the combustion air for the burners
- Energy savings of up to 25 % in comparison to other fuel-heated melting furnaces featuring side-wall exhaust gas vents
- Gas system consisting of pressure regulator, gas filter, manometer and solenoid valves
- Safe flame monitoring
- Burner technology with easy-to-service design, compliant with DIN 746, Part 2
- Designed for natural gas or liquid natural gas with 8.8 kWh/m3 - 25.9 kWh/m3
- Required min. gas pressure with full load: 70 mbar
- Operation with other fuels and/or with another gas input pressure possible
- High melting performance powered by high-performance burners and high-quality insulation
- Multi-layered insulation with lightweight refractory bricks provide the furnace chamber lining
