Chamber furnace NB 4330/S with gas supply system
Certain firing or sintering processes require a gas-fired chamber furnace. Short heating times due to the high power are a convincing argument. The chamber furnaces with powerful gas burners cover a wide variety of these processes. In the basic version the burners are manually ignited once at the start of the process. The automatic control system then takes over control of the temperature curve. At program end, the burners are automatically switched off. Depending on the process, the furnaces can be equipped with automatically controlled fan burners and safety technology for debinding. Especially in case of larger binder concentrations, gas furnaces have the advantage that the exhaust quantity can be significantly reduced as the binders are burnt off in the furnace, providing for downsizing of the exhaust cleaning.

| Bogie hearth furnace WB 14880S |
Gas supply system at a bogie hearth furnace
Furnace chamber with eight high-speed burners
Gas-fired bogie hearth furnaces distinguish by their dimensions and efficiency. The use of high-speed burners allows for short heating times. The burners are arranged according to the furnace geometry providing for a good 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 1300 °C
- Powerful, sturdy high-speed burner with pulse control and special flame control in the furnace chamber provide for good temperature uniformity
- Operation with city gas, natural gas or liquified gas
- Fully automatic PLC control of the temperature, including monitoring of the burner function
- Gas fittings according to DVGW (German Technical and Scientific Association for Gas and Water) with flame monitoring and safety valve
- Reduction-resistant fiber insulation with low heat storage provides for short heating and cooling times
- Double-walled housing provides for low outside temperatures
- Exhaust hood with fittings for further discharge of the exhaust gases
- Over-temperature limit controller with manual reset for thermal protection class 2 in accordance with EN 60519-2 as temperature limiter to protect the furnace and load
Additional equipment
- Customized furnace dimensions
- Automatic lambda control to set the furnace atmosphere
- Debinding package for debinding and sintering with corresponding safety technology
- 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 or catalytic exhaust cleaning systems
- Process documentation via Nabertherm Control Center (NCC) for monitoring, documentation and control in the use of Debinding Package II
- Other additional equipment for bogie hearth furnaces
