Troubleshooting/Consultancy

For a new application, start working with us in the early planning phases so the necessary parameters and scope can be established and a programme developed for accomplishing the task within budget and schedule constraints. For modernisation of existing processes, a field audit is required to establish parameters and scope.

Batch plants can be modernised whilst maintaining glass production. Also, furnace systems can be improved while in operation by altering the combustion system, adding bubblers and/or electric boost. The improvement of the post forming operation can be achieved on the run.

The TECO Group of companies can handle a complete glass manufacturing plant on a design/build basis, utilising your forming technology and/or forming technology provided by others. Also, we can handle segments of your project such as a batch plant, furnace, forehearth, etc, or even just the management of the project or assisting with troubleshooting, consultancy or service work regarding your existing installation.

We can literally support you from conception to completion... and beyond.

Audits & Inspections

Furnace audits and inspections are an important tool to ensure longevity of the furnace campaign and efficiency of operation with regard to fuel consumption, gaseous emissions and glass quality.

Tecoglas recommend that a furnace audit be carried out twice annually to ensure regular evaluation and review.

A typical Tecoglas audit is split into three distinct areas:

(1) Visual Structural Survey

This involves a visual “walkthrough” studying the regenerators, glass bath and superstructure for any areas of wear or movement. Any areas that require attention and/or monitoring will be identified on drawings and subsequent recommendations made. We maintain that the engineers who carry out this study are fully conversant with the original furnace design. As the study progresses, it is essential that the auditor refers to and fully understands the original design drawings.

(2) Thermal Survey

The first thermal survey is cross-referenced to the original drawings and acts as the initial reference for subsequent surveys to be compared against. The thermal imaging will plot temperatures for the furnace bottom and the glass bath. The report will consist of an overview of the thermographic condition and thermographic data recorded, together with details of any anomalies or problem areas detected. These areas are thermal imaged and photographed for identification purposes and appear on fault sheets within the thermographic report.

Follow on visits will identify any thermal changes to the structure which the visual survey may not pick up. Again, to fully interpret the results, it is important to understand the design and operation of the furnace.

(3) Operational Survey

This survey completes the audit and is required to fully understand two important issues:

(a) Is the operation contributing to any problems highlighted by the structural and thermal imaging surveys?
(b) Is the furnace optimised to its full potential with regard to fuel efficiency, emissions and glass quality?

This survey will include the following:

  • Review of past operating data
  • Flame control, burner angles and flame length
  • Port flow distribution
  • Effective use of boost
  • Any maintenance issues
  • Port oxygen control
  • Combustion equipment audit
  • Operating philosophy
  • Hot spot control
  • Air and water cooling systems
  • Thermometry issues

About us

Company portrait

Pioneering new technology
Our UK history begins in the late 1940s with the creation of a new glass manufacturing facility in Bilston, Staffordshire, UK. British Heat Resisting Glass was a manufacturer of low expansion borosilicate glass for a range of domestic oven to tableware. This company pioneered the use of electricity as the furnace fuel and developed the single phase plate electrode furnace, thereafter known generically as the “Gell” furnace, for this particular type of glass.

Recognising that a market existed for this type of furnace, British Heat Resisting Glass formed a subsidiary company, Elemelt Limited, based in Kingswinford, West Midlands, to specifically further develop this form of electric melting and extend the range of furnaces available into other areas of glass production. Over the next decade, Elemelt designed and built many electric melting furnaces in no less than 26 countries worldwide. Additionally, new electric forehearths and electric boosting systems were also developed.

Stateside Success
During the 1960s, one of the world’s major companies in the glass furnace business, Toledo Engineering Co, became the sole agent for Elemelt technology for the United States and Canada. Tremendous success was enjoyed with this relationship, with more than 150 electric melters of all types being built.

This success inevitably led to the two companies joining forces and, in 1982, Toledo Engineering bought Elemelt and renamed the company Teco Europe, specifically to clearly identify that it was part of the rapidly growing Teco Group and was based in Europe, thus increasing the opportunity for Teco to operate outside of the United States.

European Expansion
The 1990s saw a significant rise in the business developed by the new European based company, to such an extent that a second company, Tecoglas, based in Sheffield was formed. This company was specifically formed to develop fuel-fired furnaces, mainly regenerative, but some recuperative, primarily for the container and fibreglass industries.

Tecoglas is located in the same building as KTG Engineering, itself a company formed from the original KTG Furnaces Limited, specifically to provide spare parts and furnace equipment such as electrode holders and batch chargers.

In 2003, a further step was taken by Tecoglas, with the acquisition of Zedtec Limited. This company has a long history in the glass industry in the field of glass conditioning and offers a unique technical solution which has proved to be very simple and reliable to operate. The overall performance, particularly if the location determines a very high rate of glass cooling is required, has been proven and currently there are more than 160 such forehearths operating worldwide.

Unique Solutions
All of our companies operate with technical input and direction from our parent company, Toledo Engineering Co (TECO) of Ohio, USA, whose history, spanning more than 90 years, has enabled it to be recognised as a world leader in float glass plants, “E” glass plants, batch plants, container, fibre glass and speciality glass installations.

Each application is evaluated on a site-specific basis. We offer each customer a choice that can be tailored to suit their capital investment strategy, emission regulations, fuel availability and budget limitations. Because of our extensive knowledge of glass melting processes, we are uniquely qualified to assist and carry out these evaluations and subsequently provide project planning and implementation.
