Storage solutions for very fine powder
Fine powders like fly-ash, potato starch and filter dust tend will fluidize when handled. To respond to this specific issue of our customers, ESI Eurosilo has developed and deployed the shutter column system.
For recycling plants that produce very fine electric arc furnace dust (EAFD), we have built silos that are equipped with the shutter column. The center column of this reclaim system is equipped with shutters that can be programmed to open and close during the filling process of the silo. In this way the products can be handled without any problem.
Space efficiency for large quantities
As the demand for output and performance increases, limited space at plant sites becomes a true bottleneck for expansion. How to store large quantities if there is no extra space available?
A Eurosilo requires only a third of the space needed when using open stock piles. We have built silos up to 100,000 cubic meters, but technically this is still not the limit. With storage volumes varying from 500 up to 100,000 m3 a wide range of logistic chains can be served. Also strategic stocks can be realized even in large quantities. The automated material handling for filling and reclaiming is also cost saving in terms of manpower and machinery, when compared to conventional storage in an A-frame shed or in stock piles.
Storage solutions for hygroscopic material
How to avoid hygroscopic products to block due to high moisture? For customers in the Chemical industry, we have developed a reclaim solution that eliminates the risk of blockage: the proprietary slotted column.
This central column provides an open reclaim channel in the stored mass. Together with the sturdy screw conveyors, this system ensures that material, that otherwise inevitably would block up, can be fed out without any problem. Fertilizer, basic salt and minerals can be stored and reclaimed even in humid atmospheres during months in a smooth and reliable way.
Storage solutions for solid fuels.
For coal fired power plants, we have designed and built over XX silos to store coal, pet coke or pellets in the most efficient, environmental friendly and safe way.
The Eurosilo system is suitable for storing of various grades of coal and the built-in fire protection system is well proven and approved by the NFPA’s. The operation is highly automated and very user friendly. With a multiple silo system, coal blending is possible. This is controlled by the Fuel Management System (FMS) in order to achieve the highest efficiency rate. Customers consider the small footprint and the relatively low Total Cost of Ownership (TCO) as great advantages of the Eurosilo system. In Helsinki, at the Salmisaari Power Plant, we have even built a multiple silo system of 4 silos, completely underground to cope with space limitations and to preserve the landscape.
Storage solutions for sticky material
When asked to develop a storage solution for highly cohesive material such as FGD Gypsum, ESI Eurosilo came up with a compact design that incorporates 3 operational units on top of each other.
In this compact logistic solution, the suspension is pumped to the dewatering on top of the silo and from there fed and stored into the Eurosilo from which the trucks can be loaded directly underneath the silo. Instead of 3 days, the storage period is extended to over 3 months. We have built over 60 units around the world, including many repeat orders, showing the customer’s satisfaction and appreciation of the reliability in handling FGD Gypsum. This system is applicable for storing a wide range of cohesive products.
