SGT Centenary Training Day and Furnace Solutions 11- Speakers and Abstract for 8th and 9th June
“Experience with Auxiliary Combustion for NOx Reduction“ By R S Pont, Global Combustion Systems Ltd
Auxiliary Combustion is a Patented technique for reducing NOx in End -fired and Cross-fired regenerative furnaces. Modelling, pilot furnace and full scale furnace testing have been used to develop the method assisted by a grant from the EU under the FP7 programme.
The technique has been shown to be capable of reducing NOx in typical glass melting furnaces to 500mg/m3(at 8% O2) equivalent to reductions of 60%.
This paper will describe the development and the results of application to end-fired and cross-fired furnaces in the container and float glass industry.
“Application of slags and alternative batch compounds in glass batches” By Hans van Limpt, Bart Wilms, Petri Mast Sibelco Europe
In this the Centenary of the Society of Glass Technology [SGT], the Melting Technical Committee [MTC] of the SGT announce the fourth Training Day [TD4] on 8th
June and Furnace Solutions 11 [FS11] programme for 9th
Lucideon, Stoke on Trent, UK. Training Day 8th
June
With expected implementation of the BREF environmental regulations the MTC approached several previous Training Day attendees before deciding on “Energy and the Environment” as the topic of the Training Day on 8th
June.
Also celebrating their Centenary, the MTC are delighted to welcome one of the Registered Trainers from the Energy Institute – Chris Burgess, Alpha Management Solutions Ltd. Other speakers include regular participants from previous FS events - Mark Pudner (GTS), Matthew Demmon FSGT (MKD23) and Neil Simpson FSGT (Simpson Combustion and Energy).

The MTC are delighted that the conference hosts, Lucideon, will present a paper this year.
“ISO5001 – A must have for the glass industry” By Shaun Bainbridge Lucideon
ISO50001 is the latest international management system and is based around managing energy usage. The glass industry is a natural “early adopter” of the standard due to their focus on energy efficiency to ensure profitability. The paper will examine the content and structure of the ISO50001 standard and the benefits it brings to organisations in terms of improved systems of operation, reduced energy usage and positive publicity.
Reference will be made to how ISO50001 is used as a compliance route for mandatory energy audit schemes related to the EU Energy Efficiency Directive (EED) in some EU countries. The process of certification will be broken down into “bite sized” portions and some real-life anecdotes will be used to illustrate best practice and avoid common pitfalls.
The session will conclude with perspectives from an international glass manufacturer on the ISO5001 standard and the practical issues around implementation and certification and the drivers for having the system.

The Glass industry is more and more interested into possibilities for further improvement of the yield, quality and energy efficiency of the glass making process. The focus is shifting into the research on improved batch compositions with low-melting batch compounds. To support these goals Sibelco investigates the applicability of alternative batch compounds and slags.
A slag is an amorphous by-product from e.g. the metallurgic industry with limited industrial applications. Slags are silicate compounds with high levels of CaO, MgO, Al2
O3 and/or Fe2 O3 not seldom with contaminants like heavy
metals, sulfuric compounds and chloride species. One of the advantages of the slags will be to be able to reduce the use of traditional raw materials like limestone (CaCO3 (Al2
), dolomite (CaCO3 O3 .MgCO3
source) or iron minerals and additionally less reaction energy will be required for the batch melting process.
Additionally calcined batch compounds like MgO and calcium-silicates - like wollastonite - will reduce the energy consumption of a glass furnace and reduce the release of CO2
.
This paper will show the advantages of iron-silicate slags as coloring agent for amber glass and colored flat glass as well as the applicability of slags for E-glass production. The advantages of alternative minerals like MgO and wollastonite will be demonstrated.
“Fuel Efficient Forehearth And Distributor Systems” By Simon Parkinson. Parkinson-Spencer Refractories Limited.
Although the glass melting furnace is by far the single largest consumer of energy in a glass plant and naturally the focus for energy efficiency monitoring and improvements, correct forehearth and distributor system design can provide significant energy and cost reductions not only by reducing the actual required fuel consumption but also by increasing the forming efficiency.
The furnace supplies the glass to the distributor and forehearths which are then responsible for cooling the glass from melting temperatures to forming temperatures whilst achieving a high degree of thermal homogeneity and temperature stability throughout the glass delivered to the forming process. This process of glass thermal conditioning normally involves controlled cooling of the glass as it passes along the distributor and forehearth channels from typical furnace exit ( throat riser ) temperatures of 1350°C
