In end-port regenerative type furnace, the heating is provided by mixing the fuel injected through burners installed in the combustion chamber under the exhaust gas/inlet air ports and the hot combustion air

The combustion air, before being blown in the combustion chamber, is heated-up at high temperature inside the regenerator system which is made of two towers made of special bricks (checkers) realized with high resistant refractory materials. Inside the regenerators the exhaust gases and cold air are alternatively and separately forced to flow respectively downward and upward. The system works alternating the regenerators (one regenerator is heated by hot exhaust gases and the second regenerator is cooled by cold combustion air).

Due to this characteristics the hot air temperature can reach values up to and beyond 1.300°C depending on furnace size, design, materials, etc. thus granting a high overall energy efficiency to the furnace.

In return the regenerative furnace is constantly working under severe thermal, chemical and mechanical conditions and therefore an appropriate design and choice of materials is needed in order to guarantee the best results in performances reliability and lifespan.

The end port regenerative furnace is the most popular furnace in production of tableware and container glass.

The main features of regenerative furnace are:

  • Low energy consumption
  • Low emissions
  • High specific pull (tpd/m2)
  • Reliable technology
  • Good flexibility to pull variation
  • Easy operation
  • Extended lifetime

Our regenerative furnaces can produce glass in the range from 20 ton/day up to 350 ton/day with or without boosting systems.

Type of glass:

  • Soda-lime
  • Crystalline
  • Light borosilicate

Fields of application:

  • container glass
  • tableware
  • Kitchenware
  • pharmaceutical
