Cullet preheating equipment using unused waste heat
IHARA FURNACE CO.,LTD.
Technology / Service Summary
The melting process accounts for approximately 60% of the energy consumed in a glass melting furnace.
Conventional technology for recovering unused waste heat has reached its limit, and it is not possible to expect a significant reduction in GHG emissions with the energy-saving technology used to date.
Therefore, we focused on technology that uses unused waste heat to heat glass raw materials, and developed a cullet preheating device that controls the mixing ratio with the batch in the post-process.
Purpose
To reduce GHG emissions from glass melting furnaces
Feature
Hybrid method of direct and indirect heat exchange with exhaust gas
Combining two heating zones achieves high heat recovery rate and long life
Effect
With a cullet utilization rate of 80% in glass melting furnaces, energy savings of around 10% are possible
