Alternative Melting Furnace Concepts

Alternative Heating Technologies
The application of alternative heating technologies depends on the requirements for melt quality, productivity and energy efficiency. In principle either electrically or gas-fired furnaces can be used. In this context, with respect to costs the local pricing for the alternative energy play a decisive role.

Gas-Fired
Gas-fired furnaces are ideal for melting, particularly if equipped with exhaust gas discharge over the crucible edge. Side exhaust gas discharge is best if a high melt quality is required. However, a higher melt quality means a lower energy efficiency since a fuel-fired furnace with side exhaust gas discharge consumes approx. 20-25 % more energy than a furnace with an exhaust gas discharge over the crucible edge.

Fuel-fired furnaces provide for optimal energy efficiency in combination with highest melt quality due to their burner system that includes heat recovery via recuperator. The hot exhaust gases from the furnace preheat the combustion air for the burner via a heat exchanger. This system leads to savings of up to 25 % compared to conventional fuel-fired furnaces with a side exhaust gas discharge.

Electric Heating
If the melt quality and energy efficiency take priority, an electrically heated furnace is the best choice. The heating is controlled very steadily and precisely. The melt is not polluted through immissions from a fuel-fired heating. Electrically heated furnaces can achieve up to 85 % of the melting performance of fuel-fired furnaces with a side exhaust gas discharge. If the furnaces are used only for holding, we recommend the T…/10 models, which are very energy efficient due to their very good insulation and reduced connected load.

Chamber furnace NB 4330/S

Certain heat treatment processes require a gas-fired chamber furnace. Short heating times due to the high power are a convincing argument. The chamber furnaces with powerful atmospheric 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. Depending on the model, these furnaces can be upgraded with fully automatic fan burners and additional accessories.

  • Tmax 1300  °C
  • Powerful, atmospheric burners for operation with liquified gas or natural gas
  • Depending on the application, special positioning of the gas burners with flame guidance provides for optimal temperature uniformity
  • Fully automatic temperature control
  • Gas fittings with flame control and safety valve in accordance with DVGW (German Technical and Scientific Association for Gas and Water)
  • Multi-layer, reduction-proof insulation with light-weight refractory bricks and special back-up insulation result in low gas consumption
  • Self-supporting and rugged ceiling, bricks laid in arched construction. Only fiber materials are used which are not classified as carcinogenic according to TRGS 905, class 1 or 2.
  • Exhaust hood
  • 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

Chamber Ovens Electrically Heated or Gas-Fired

The chamber ovens of the KTR range can be used for complex drying processes and heat treatment of charges to an application temperature of 260 °C. The high-performance air circulation enables optimum temperature uniformity throughout the work space. A wide range of accessories allow the chamber ovens to be modified to meet specific process requirements. The design for the heat treatment of flammable materials in conformance with EN 1539 (NFPA 86) is available for all sizes.

  • Tmax 260  °C
  • Electrically heated (via a heating register with integrated chrome steel heating elements) or gas-fired (direct or indirect gas-fired including injection of the hot air into the intake duct)
  • Temperature uniformity up to +/- 3  °C according to DIN 17052-1 (for design without track cutouts)
  • High-quality mineral wool insulation provides for outer temperatures of < 25  °C above room temperature
  • Only fiber materials are used which are not classified as carcinogenic according to TRGS 905, class 1 or 2
  • High air exchange for fast drying processes
  • Double-wing door for furnaces KTR 3100 and larger
  • Over-temperature limiter with adjustable cutout temperature for thermal protection class 2 in accordance with EN 60519-2 as temperature limiter to protect the oven and load
  • Incl. floor insulation
  • Defined application within the constraints of the operating instructions
  • NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
