Waste heat recovery drives energy efficiency in glass

Guardian Industries’ Glass Group has invested more than £4 million ($6 million) to develop and implement a Waste Heat Recovery System at its Goole glass manufacturing plant in Yorkshire, in the UK.

The system uses a complex method of capturing waste heat from the float glass furnace without disrupting the delicate convection currents, which continually flow inside the furnace as the batch material is turned to molten glass.

The heat recovered will provide half the electrical energy needed to operate Guardian’s full float line and will reduce CO2 emissions by some 6,000 tons per year.

Pablo Isasmendi, Plant Manager for Guardian Industries UK, explained that ‘there’s a viable way to reduce energy consumption and carbon emissions from the float glass manufacturing process.’
