Glory Hole Furnace

Multiflame Glory Hole

The Glory Hole furnace is the essential tool for the artist who has to work the glass into various shapes. This furnace is easy to use, safe, reliable, and fast in the heating.
Years of experience had with our customers allowed us, starting from more complex and expensive types of furnace, to get a functional product easy to use, and wholly in conformity with directives regarding the safety, which can be installed both in industrial contest and in the centre of towns.
As a consequence, the more interesting characteristic of such furnace is a very good ratio quality/price.
Our Glory Hole furnace is easily transportable, thanks to the reduced weight and the wheels, and can reach high temperatures very rapidly, thanks to the materials which compose its internal part.


Structure of the furnace

It is built by a circular steel structure which is installed on a frame made of iron beams and tubes.
The heating chamber is filled by high density compressed ceramic fibre with a maximum working temperature of 1450°C. The mouth is made by refractory material mainly composed of mullite material, which is cast and vibrated in order to obtain the requested shape.
The internal bottom of the furnace, where some glass could fall down, is proctected by a dense refractory material plates.
The reductions are made by high compressed ceramic fiber (it can be made by refractory material, under request of the customer), and are fixed on the external steel frame of the furnace with manual movement.
The furnace can be composed by N. 01 or N. 02 or N. 03 working-mouths which can be equipped with a maximum of N. 02 reductions each.
The furnace is equipped with wheels that are installed on the supporting-frame and allow an easy and smooth displacement of the furnace inside the glass factory.


Fully Automatic combustion system

The combustion system is directly installed on the heating furnace so to reduce the encumbrances to the minimum; it is supplied with all the necessary components to control and regulate the furnace automatically, such as the gas – ramp and the electric control board which contains all the devices necessary to turn the burner on or off. A UVZ detector continuously controls the presence of the flame of the burner and when it is necessary acts on the security valves interrupting the gas flow to the burner. The regulation of the furnace-combustion is completely automatic and the temperature control is made by a digital controller Honeywell installed on the panel control.

Gas Multiflame burner
with automatic starting system and flame detection

The air/gas combustion burner is made of stainless steel and refractory material and equipped with a connection-piece to link the burner itself to the furnace; this connection inside is completely covered by refractory material.
The burner is multiflame type, with the exposed part inside the furnace made in refractory material with holes in order to permit the best heat up results, with the less possible noise.
The regulation of the burner has to be made just one time at the start up of the furnace, and after it works automatically. The burner is supplied with an ignition electrode and a UVZ detector that continuously controls the presence of the flame. The furnace is delivered, fully installed, tested and ready for use; it is painted with silicone-aluminium fir to resist at high temperature.
