Cost-efficient process heating solution at glass recycling plant

Published:  09 February, 2017

Recycling firm Ward Recycling Ltd (WRL) approached EOGB to provide an improved and more cost-efficient process heating solution at its glass beneficiation plant in Middlesbrough.

Operating since 2012, the plant processes glass collected from household, municipal and commercial sources to make glass grit which can be used by companies as an alternative to traditional abrasive media such as silica sand or gravel. WRL glass grit is often used as an environmentally-friendly alternative for water treatment and filtration applications.

The heating system is a critical element of the recycling process to sterilise the glass and remove any contaminates such as metal or paper.


EOGB carried out a full assessment of the combustion process at the site, providing a detailed report which gave a clear overview of the current burner performance and the savings that could be made with an upgraded system.

WRL was advised that by introducing a two-stage or fully modulating burner to the process, in place of the current single-stage operation, there would be less temperature fluctuation and more balanced heating which would lead to increased efficiency and significant cost savings.


By integrating a Baltur two-stage burner into the existing control panel in place of a single stage burner, the system now benefits from higher reliability, a reduction in CO2 and NOx emissions and significantly lower heating bills.

Steve O’Neill, technical specification engineer at EOGB, said: “Previous operational issues have been eradicated and we have the option to implement further energy saving measures in the future. The upgraded system is highly-efficient and is expected to provide trouble-free operation for many years to come.”

Paul Stonehouse of Ward Recycling Ltd, said: “As a result of changing to an EOGB system we have not only been successful in achieving the standards required by our accreditations but have also significantly reduced our fuel usage by an average of 15% per month. As an environmentally-focused company this reduction in fuel usage and carbon footprint only goes to further enhance the value of the products we make.”

The EOGB/Baltur commercial gas burner range is available with outputs from 50kw to 10,850kw. The burners have low CO and NOx emissions and are easy to install which enables a trouble-free commissioning which is fully supported by EOGB engineers.
