Technical papers
Every year we produce a number of technical articles, some for publication in technical journals, whilst others are the basis for technical papers given by our people at conferences or symposia.
We are pleased to be able to provide these documents for a wider audience through the web site, where they are available for download as PDF files from this page.
If you have any problems downloading from this side please contact us.
Gas heating systems for working ends and forehearths
This paper looks at the development of the premix gas heating system for distributors and forehearths, and includes a description of a modern high-pressure system. The important subject of system safety is also covered.
Thermal Homogeneity Index – the real truth
Forehearth operation is usually judged on the basis of a quasi-mathematical analysis of 9 glass temperatures measured by three triplex thermocouples located at the end of the equalising section. This article explains how equipment tolerances and other inaccuracies mean that the results are not quite as definitive as is often claimed.
Forehearth colouring – a technology update
Forehearth colouring is an interesting concept providing special flexibility for the glass producer. Here you can read about the latest colouring technology being used for containers, glass blocks, tableware and rolled plate.
Electric boosting – a technology review
Another in our series of technology reviews, this one covers the important subject of electric boosting systems for conventional furnaces. Although the basic technology has been in use for more than 50 years, there are still a number of technical issues that are less well understood. This article will help you in this respect.
Batch charging technologies – a review
Batch charging is an important but often neglected aspect of glass melting, and this paper describes the various options for conventional furnaces, listing the advantages and disadvantages of each system.
SORG melting technologies for special glasses
The special glasses referred to in the title are Pyrex® type borosilicate glass, C glass for insulating wool, basalt or similar mineral for stone wool insulating fibre, fluoride opal glass and borosilicate E glass for continuous filament textile fibres. In each case the melting problems are described together with the SORG furnace design best suited for that particular glass. Examples of recent SORG installations are given for each glass.
