With environmental concerns at the forefront of glass manufacturers' minds, reducing energy use is a priority. To achieve this maintaining the highest quality and optimized OPEX, Fives developed a proprietary L.E.M.® technology for our high-performance Prium® Float-Melt furnace.
As a leading independent turnkey provider, Fives offers design and supply services based on broad experience of more than 20 float lines delivered in the last two decades.
Prium® Float-Melt
Versatile melting solution
The Prium® Float-Melt furnace is designed to produce architectural, solar and automotive glass over a wide spectrum of glass colors and thicknesses, from ultra and extra-clear to light and dark tinted, from ultra-thin to thick.
Fives standard glass lines can achieve up to 1,000 tpd melting capacity and can incorporate a provision for electric boosting systems allowing additional flexibility.
Fives provides versatile furnace design to match the required quality level, according to ATSM and EN standards, and up to the most demanding optical homogeneity and melt quality.
L.E.M.® Technology
Enhancing efficiency and quality
The L.E.M.®, Low Energy Melter technology, dramatically reduces heat losses and gas consumption without compromising on quality.
This is achieved by multiple improvements to the melting and fining process:
- Reduced working end losses by limiting glass recirculation
- High specific pull rate, thus limiting wall losses compared to useful melting energy
- Maximum fume heat recovery through optimized regenerator efficiency
- Increased combustion efficiency by ideally designed combustion space
- Modulated insulation for refractory walls
| These proprietary technologies enable unrivaled low energy consumption, down to 1,200 kcal/kg (5 GJ/tonne) for architectural applications. |
