Alumino Silicates CASTABLES Réunion Island

Castables for Réunion’s Combined Sugar and Power Plants

Linings That Survive Start-Ups and Shutdowns.

Durocast: Alumino Silicates Castables Shipped to Le Port

On Réunion, the island’s two sugar factories — at Bois-Rouge in the north-east and Le Gol in the south-west — sit beside thermal power plants that burn bagasse during the harvest and other fuels outside it. These boilers, together with waste-treatment and industrial furnaces, carry most of the island’s refractory demand.

Durocast (Pty) Ltd ships alumino silicates castables to Réunion from South Africa through Le Port, the island’s main harbour.

Thermal Cycling Is the Hidden Enemy

A boiler that switches fuels, ramps load with the grid or comes on and off line expands and contracts its lining every cycle. Over time, that cycling opens cracks, loosens anchors and causes spalling — often a bigger threat than peak temperature. Durocast low cement castables offer better strength and refractoriness than standard grades, and an insulating backup layer helps even out temperature swings across the lining.

Grades for Réunion’s Boilers and Furnaces

Orders for Réunion typically include Durocast LC for the dense working lining, Durolite high-strength insulation and Thermolite general-purpose insulation, Duroflow self-flow castable for intricate burner shapes and Durapid for fast repairs. The full family is described on the Alumino Silicates Castables page.

Where Durocast Castables Are Used on Réunion

Power-plant boilers — furnace walls, burner zones and refractory floors.
Sugar-factory process heat — boiler casings and doors.
Waste treatment — incinerator combustion chambers.
Burner quarls — Duroflow cast without vibration.
Insulating backup layers — Thermolite and Durolite.

The Industries Durocast Supplies on Réunion

From Saint-André to Saint-Louis, Durocast castables serve:

Power generation — bagasse and multi-fuel thermal plants.
Sugar manufacturing — Bois-Rouge and Le Gol.
Waste treatment — incineration.
Food and beverage — boilers and ovens.
Industrial maintenance — contractors and engineering shops.

Data That Travels With the Material

Each shipment to Réunion includes product data, installation instructions and dry-out schedules, so local contractors can install with confidence. Grades are batched under Durocast’s own quality control — read more on our About Us page.

Anchoring and Expansion Detailed Up Front

Because cycling damage starts at anchors and joints, Durocast reviews the lining design — thickness, anchor pattern and expansion allowance — alongside the grade, so the new lining is built to move without cracking.

Why Réunion Operators Choose Durocast

Low cement grades with strength for cycling duty
Insulating backup layers that smooth temperature swings
Duroflow for complex burner shapes
Lining design reviewed with the grade

Frequently Asked Questions

Why do boiler linings crack on Réunion plants?

Repeated heating and cooling during fuel changes, load swings and shutdowns stresses the lining. Better castable strength, insulation and correct anchoring all help.

Which Durocast grade suits a cycling boiler?

Durocast LC low cement castable, usually backed by Durolite or Thermolite insulation.

Can you make complex burner shapes?

Yes — Duroflow self-flow castable fills intricate forms without vibration, and shapes can also be precast.

How are castables shipped to Réunion?

By sea from South Africa to Le Port, with installation and dry-out documentation included.

Is there a castable for quick repairs between campaigns?

Durapid quick-repair castables can be installed in hot areas and returned to service quickly. The full range is on the Alumino Silicates Castables page.
