The Sorg Group is celebrating a year of successful Clean Melter operation at the Crisal glass plant in Marinha Grande, Portugal.
The melter replaced the previous regenerative F1 Endport furnace at Leerdam Crisal Glass (LCGlass)’s Portuguese site.
The Clean Melter is an oxy-hybrid melter designed for an electricity share of up to 80%, with the remainder provided by gas.
It has built-in capability to support hydrogen-powered heating in the future.
With a melting surface of approximately 55 m², the melter will help reduce Crisal’s CO₂ emissions as part of its sustainability strategy.
Sorg supplied the design and equipment, which included electrical and fossil heating systems.
Supervisory Control and Data Acquisition (SCADA) furnace software was also installed.
In addition, Sorg provided the conditioning system, consisting of an STW type distribution channel and five forehearths of the STF type.
The dismantling of the previous melting tank and construction of the Clean Melter, including heating-up and filling, was carried out by Sorg’s subsidiary SKS.
The Sorg Group thanked Crisal and LCGlass for their co-operation in the project.
The investment was supported by the Recovery and Resilience Plan (PRR) under the ECP Agenda – Ecocerâmica e Cristalaria de Portugal.
