Furnace and Forehearth Drain Systems

DRAINAGE TYPE MO DISK

GENERAL

The drainage system type Molybdenum is designed for the drain of bottom glass from melting furnaces and forehearths or of condensates from flue gas ducts. It is designed for periodic operation.

The drain consists of a water-cooled housing and a head with a special arrangement of heat-resistant material. The head contains a plate electrode made of molybdenum. 

This head is both the drain nozzle and the electrode. An exchangeable attachment nozzle is adapted to it. Depending on the type of glass and the temperature, the attachment nozzle is adapted to the desired working range of the pull rate.

The drain is pressed with the housing against a hole in the bottom block or in the flue gas duct.

It is designed with direct electrical heating and is operated with power control. For this purpose, current is conducted from the drain to a counter-electrode in the glass.

Furthermore, a gas-air burner heating with flame monitoring is installed for the start-up of the drainage.

The drainage system type Molybdenum is available as an integrated part of a complete plant or as a stand-alone system. As the drainage is normally integrated into a complete plant, the counter electrode is not part of the standard scope of delivery.

FEATURES

  • Non-continuous operation
  • Pull rate adaptable to different operating conditions
  • Easy start of the drain after standstill
