Direct resistance heat drh

The Concept:

DRH Furnaces drive a current directly through the product utilizing the resistive properties of the product to provide the heating energy for the process.

The Advantages:

  • Higher yields due to the attainable inert atmosphere
  • Minimal thermal losses due to extremely efficient energy conversion from electricity to useful heat
  • The “Live product” removes the need for conventional heating methods and thus greatly reduces the plant size
  • Generating heat at the core of the furnace allows for cooler wall temperatures and thus the refractory lining has a better service life

Typical Applications:

  • Ultra high temperature treatment of carbon graphite
  • Reduction of mineral ores
  • Specialised non-oxidising chemical reactions
