Oxygen for glass melting

Boosting productivity with combustion air enrichment

In recent decades, the glass industry has sought to improve the efficiency and productivity of its furnaces. One solution to enhance the melting process is enriching combustion air with oxygen.

The oxygen-air mixing system is designed and customized according to process requirements: it ensures correct and rapid gas homogenization and uniform distribution of the mixture inside the furnace.

We work with customers to determine the most suitable and efficient location for installing the mixing system, thereby maximizing the benefits achieved.

Oxyboosting

Maximizing production and improving glass quality with oxygen burners

Oxyboosting allows production to be increased and glass quality to be improved while reducing CO2 emissions, through the installation of specially designed SIAD burners that ensure efficient and homogeneous glass melting.

Careful selection of the burner location is essential for the success of the application. We ensure precise control of fuel and oxidant flow rates to the burners, maintaining the correct combustion ratio. In addition, the alarm control system, integrated into the PLC, provides maximum safety and reliable process operation.

Staged combustion

Minimizing NOx formation

By introducing pure oxygen into specific areas of the furnace, combustion can be optimized and NOx formation minimized.
By positioning oxygen delivery lances, the interaction between oxidant and fuel is optimized, improving the overall energy efficiency of the glass melting process. This approach makes it possible to create staged combustion, in which the fuel “reacts” with oxygen in multiple phases of the process, greatly reducing NOx formation.

The process involves the injection and ignition of acetylene.

The controlled combustion of acetylene forms carbon that deposits uniformly on the walls of the container mould. The system is equipped with safety measures for the correct management of acetylene, from storage through to the delivery system.

The “acetylene moulds” line specifically designed for lubrication in glassworks has a low phosphine and arsine content, which are the main causes of low product quality.
