Installation of an air vein burner for aluminum slag treatment

Soluciones Integrales de Combustión has carried out the installation and start-up of an air vein burner for aluminum salt slag treatment in a recycling and recovery plant for waste and components in the community of Castilla y León. 

In the installation of this project, Soluciones Integrales de Combustion has implemented a JVA-C 4200 model air vein burner designed by E&M Combustión engineering company, with a fan and channel, which will operate with natural gas as fuel. The combustion equipment will allow the continual improvement process undertaken at the plant to continue through the treatment of aluminum oxide – known as paval – generated in the aluminum waste recycling processes.

The air vein system is specifically designed by the company for drying the paval, which will allow, at the same time, to minimize gas emissions from this process.

Aluminum slag treatment and emissions reduction

The owner company has selected this aluminum slag treatment procedure over other processes also considered among the “Best Available Techniques (BAT)”, with the aim of minimizing emissions and ammonia clouds caused by certain atmospheric conditions.

The saline slag is obtained as a consequence of the use of salt during the melting process to avoid the unwanted oxidation of the liquid aluminum inside the furnaces. Said saline slag is completely recycled and recovered, becoming paval, an element of use in cement plants. In this way, the circle of the recovery of aluminum waste is closed.
