Carbon Furnaces Technologies

Open Carbon Baking Furnaces?

Furnace Rebuild?

We offer the best value due to our extensive experience in Open Carbon Baking Furnaces. We have been specializing in development, design, construction and rebuilds of furnaces for over forty years.

With our Australian partners we are amongst the world’s top 3 suppliers of Anode Cleaning Stations, Anode Handling Systems and Refractory Maintenance Equipment.

As an independent engineering and consultancy company, we know all existing carbon furnace designs in the world: therefore, we know the advantages and disadvantages of these designs.

This is why we can offer the best possible design solutions within any given building or process limitation. Aside from building from scratch, we are specialized in the rebuild of existing furnaces and

the rebuild of closed furnaces to open furnaces. In a safe way, guaranteeing consistent top quality,

with maximum cost efficiency.

AND: in case of rebuild, we guarantee our time schedule, so you know exactly what to expect

and how to plan your production.

State-of-the-Art

Carbon Baking Technology.

TOP quality anodes baked under optimal furnace design, with totally controlled firing system and

clean emissions: more anodes, less costs, with maximum consideration towards environment and human resources. In short: the ideal working and producing conditions for Carbon Baking.

We offer nothing less than the best. Be it in greenfield built or in the rebuilding of furnaces.

Meaning:

• Guaranteeing consistent top quality of all baked anodes.

• Energy Consumption: < 1.7 GJ/t (baked anodes) Pitch burn combustion efficiency up to 99.84%.

• Emissions in accordance with international standards Clean off-gas & no collecting of Tar!

• Production capacity: > 60.000 ton/fire baked reject < 0.2%.

• Flexibility in Long Term Operation important in case of amperage creep.

• The Lowest Refractory Maintenance Costs.

In order to make our design work perfectly and to produce the best Anodes, there are three

imperative conditions:

1. The right Refractory and Tub design & the best available Refractory Materials, based on knowhow

1. and experience including modeling, choice of materials and specifications.

2. Advanced Firing and Control System, combining the latest technologies with thorough understanding 1. of operators, process engineers and Smelter Management needs.

3. Specialized Anode Handling Equipment, an experience based selection of MPM’s conveyors,

1. cleaning stations, etc.

This introduces CFT’s best practices in furnace operation and refractory maintenance.

Our design of a CFT baking furnace is based on:

1. Safe Operations and Safety during Construction.

2. Healthy and ergonomic working environment.

3. Maximum productivity and quality of the anodes.

Detail A: No tripping hazards in our design.

The side wall insulation is completely covered by the concrete tub console and anchored to the Tub.

Detail B: The design can be made suitable for all anode dimensions with either vertical or horizontal packing of anodes.

Detail C: Improved pre cast flue top, without air ingress and the risk of burning the operators feet.

Detail D: A new design for precast side wall insulation that is safer and faster to install but provides as high levels of insulation to typical designs.

Detail E: Starter blocks for faster and safer flue wall renewal.

We can offer:

• an unique and proven Refractory System design,

including Project Management, Project Management

Support to the client, Installation Supervision,

Profile

Aaron started his career in 2011 within the civil contracting firm Pentacon which is based in Brisbane, Australia. The Australian partner of Carbon Furnaces Technologies (CFT). He worked on civil construction projects throughout South-East Queensland, as well as the Black Coal basin and Coal Seam Gas Basins within Queensland.

In 2017 Aaron joined CFT and immediately began working on engineering for refurbishments of existing furnaces. He is equipped with the skill of being able to produce technical drawings and therefore draft and plot conceptual and final plans for any Furnace Design.

Joining the team as a young civil engineer and learning from the experienced colleagues around him, he has already built up credit within the industry. In 2018 he helped finalise the engineering for Century’s Rebuild of Furnace D at Vlissingen, and subsequently supervised the carrying out of the Rebuild which took place in 2019.

In 2020 CFT was awarded the Engineering to retrofit TRIMET’s existing Furnace into a CFT design. Aaron’s role within this project was pivotal, having completed the Planning; Engineering; and Supervision alongside the team from start to finish.

2021 has seen Aaron’s development within the industry progress even further by being involved in the digitalization of a Closed Baking Furnace’s drawings, while simultaneously aiding Lead Engineer Harry Sebel in redesigning elements within the furnace.

Aaron has also begun carrying out audits and inspections on numerous furnaces throughout Europe and North America. These audits are an integral part of the process to develop the most efficient furnace.
