the performance of the best regenerative furnace by taking advantage of the highest quota of waste gas heat, and it includes a robust, easy to manage and cost effective SNCR system for NOx abatement.


“Solutions to Practical Problems, affecting Melting & Life, in Glass Furnaces”. By Stuart HAKES FIC Ltd


The presentation will cover high wear areas such as doghouse corners, throat, weir walls, sidewall electrode blocks, floor area around bubblers and flux line. It will offer innovative and new approaches to these problems. In addition, it will look at other common problems in glass furnaces such as electrode wear and breakage and glass conditioning in the forehearth.


to typical gob temperatures of 1150°C with a consequent approximate three fold increase in the glass viscosity. Although a significant amount of heat needs to be removed, additional controlled and targeted heat input is also required to ensure that a high degree of temperature uniformity is achieved throughout the body of the glass at the feeder spout.


The fuel consumption of a particular glass melting furnace depends very much on the glass throughput but the fuel consumption of a forehearth and distributor depends on many other factors covering design, operation and maintenance aspects. This paper reviews the influence that the design, operation and maintenance of forehearth and distributor systems can have on their ultimate fuel consumption and illustrates the fuel and cost savings that can be made.


“CFD based control Glass furnace control system based on time transient computer model” By A.F.J.A. Habraken, J.P. van der Dennen, P.J. van Santen CelSian Glass & Solar B.V


Conventional Model based Predictive controllers (MPC) use a process model that is derived from experiments on a furnace. Such control system is limited to the tested operational area. Instead of using field data the empirically derived process model can be exchanged by validated CFD simulations. Dynamic computer models do not only describe the furnace time transient dynamics and important correlations in a very accurate way, but they also present the furnace behaviour in a much broader operational window. Therefore rMPC (control based on dynamic computer models) enables control functionalities over the complete operational area and enhances the controllability of the furnace. CFD models of furnaces and forehearth systems used for process improvement projects are now used in the engineering phase of rMPC control systems and therefore are re- capitalised upon during In this presentation, detailed dynamic modelling results of a furnace are discussed, and examples are given on the application of a CFD model in a control system.


“Oxygen Injection with a Linde difference“ By Alessandro Curti and Neil Simpson


When a premature regenerator failure reduced glass production on an end-fired container furnace in Italy an innovative solution was successfully implemented. The presentation will review the options considered, the solution with results and potential other applications of this technology.


“Centauro, a solution for glass furnace advanced heat recovery, including a SNCR plant”. Giampaolo Bruno, Ernesto Cattaneo, Giorgio Minestrini, Alessandro Mola, Francesco Prosperi,


Centauro is an innovative hybrid ceramic/metallic system for heat recovery in glass furnaces, a brilliant and cost-effective solution to solve the most frequent problems related to a conversion from unit melter to end port, the optimum solution to increase the plant efficiency beyond

“Primary NOx Reduction On Regenerative Glass Furnaces” By Gary Laird Elster


A two part paper, firstly reviewing the newest ‘Eclipse’ Brightfire 200 gas burner with a focus on it’s ability to significantly reduce NOx levels in regenerative glass furnaces. Secondly, introducing the ‘Eclipse’ staged combustion system, a tried and tested technique of running furnace burners in reducing conditions, while injecting an additional source of oxygen later in the combustion process and thus minimising NOx emissions while still maintaining normal levels of CO.


“How Fused cast AZS Properties Influence glass contact behaviour” Dr Michel Gaubil and Bruno Malphettes SEFPRO


AZS fused cast products properties have a direct impact on Glass contact behaviour that influence lasting life and glass quality level. Particularly, we will discuss internal structure of Fused Cast AZS soldier block, at a macroscopic and microscopic level, and the relation with corrosion resistance and glass defect ability


All presenters who are not members of the MTC are eligible for entry ‘The Michael Garvey Award’ (for the day's best paper) courtesy of Guardian Industries Co. The recipient of the award is decided by members of the MTC present on the day and remembers the untimely loss of Michael Garvey, who was killed in a climbing accident.


Costs £120 per person per day plus VAT and 50% discount for SGT members. For those attending both days the discount covers the cost of SGT membership! Places will be limited to a maximum of 100 so please book early to avoid disappointment. Visit http://www.furnacesolutions. co.uk/ to register.


The MTC have managed to keep costs to attend these events as low as possible due to the generosity of the many sponsors. The sponsors so far this year are Calumite, CelSian, DSF Refractories, Elster/Honeywell, FIC, Fives, Fosbel, Glass Technology Services, Global Combustion, Harbison Walker International, IRE, Praxair, PSR and Tecoglass/Zedtec in addition to Glass Worldwide, IOM3


, Glass International with, of course, the hosts


Lucideon. The MTC have one new sponsor so far for 2016, Sibelco and there are two spaces for anyone wanting to sponsor. Please contact Christine BrownChristine@sgt.org if you would like to support.


The intent is to launch the 2nd Compendium of Glass Melting at the meeting.


If anyone has any technical papers that they wish to have included please email Christine BrownChristine@sgt.org This year the MTC are holding an additional Furnace Solutions Centenary on 8th September as part of the ESG and SGT Conference in Sheffield and launch of a second Compendium but more details will follow on this event and topic.


The MTC look forward to seeing you in June at Stoke. Neil G Simpson BEng(Hons) CEng MEI FSGT MIRefEng
