Eco-friendly iron making in Brazil

Clyde Materials Handling product story

Clyde has developed a system which uses charcoal, a hitherto waste product, and turns it into a fuel used in the manufacture of pig iron in mini blast furnaces.
Brazil, world renowned for its coffee, nuts and glorious beaches, also has the world's largest known deposits of iron ore.
Despite its natural riches, Brazil is also renowned for the destruction of its environment.
Clyde Materials Handling is playing its part in helping to improve the environment and ecology in Brazil.
In association with a well known Brazilian company, Clyde has developed a system which uses charcoal, a hitherto waste product, and turns it into a fuel used in the manufacture of pig iron in mini blast furnaces.
The injection system used is a scaled down version of the many systems installed around the world, using Clyde technology, which are designed to accommodate a wide range of coal types including low cost non-coking coals.
The waste charcoal is injected into the tuyeres of the blast furnace at a controlled rate.
This process increases the efficiency of the furnace and can provide savings of up to $6 per ton of metal produced.
The resulting efficiency allows the operators to sell their products at reduced prices while increasing profits.
Advanced fuel injection systems play a major role in helping steel manufacturers reduce costs and a significant benefit of the tuyere injection system is the opportunity to reduce blast furnace fuel costs.
It also provides the opportunity to control flame temperature and the furnace thermal profile, reduces the likelihood of slipping and hanging and increases the productivity of the furnace.
Many of the furnaces in Brazil are located in remote areas where sophisticated equipment is not available.
For the Clyde systems this is quite normal and due to their simple, innovative design which, combined with Clyde's proven technology and reliability, means that sophisticated tools and equipment are not required to keep these units operational.
