Gas-Fired Bogie Hearth Furnaces up to 1400 °C for Firing or Sintering in Air or under Reducing Atmos

Gas-fired bogie hearth furnaces distinguish by their unique efficiency. The use of high-speed burners allows for short heating times. The burners are arranged according to the furnace geometry providing for a optimum temperature uniformity. Depending on the furnace dimensions, the burners can alternatively be equipped with recuperator technology to save energy. The high-quality, long-life fiber insulation with storage capacity provides for short heating and cooling times.

• Tmax up to 1400 °C, depending on furnace design
• Powerful, sturdy high-speed burner with pulse control and special flame control in the furnace chamber provide for optimum temperature uniformity
• Operation with city gas, natural gas or liquified gas
• Fully automatic PLC control of the temperature as well as monitoring of the burner function
• Reduction-resistant fiber insulation with low heat storage provides for short heating and cooling times
• Dual shell housing provides for low outside temperatures
• Exhaust hood with fittings for further discharge of the exhaust gases
• Over-temperature limiter with adjustable cutout temperature for thermal protection class 2 in accordance with EN 60519-2 as temperature limiter to protect the furnace and load
• Defined application within the constraints of the operating instructions

Additional equipment

• Automatic lambda control to set the furnace atmosphere
• Exhaust air and exhaust gas piping
• Recuperator burners utilizing part of the waste heat in the exhaust tract to preheat the combustion air and considerably contribute to energy saving
• Thermal exhaust cleaning systems
• Process control and documentation via VCD software package or Nabertherm Control Center (NCC) for monitoring, documentation and control
