As part of the EECB activities of technology transfer and exchange of knowledge, our Swisscontact colleagues of the Latin America Clay Brick Project (EELA) would like to invite South African Clay brick makers to participate in a trade mission to Brazil. This is an opportunity that will allow South African brick makers to see and learn about the furnaces that have been widely utilized in the Northern region of Brazil.

As part of this mission, there will be the opportunity for the brick makers to see and enquire about the types of kilns they operate, these being the Mobile Tunnel Kilns, Cedan Kilns and the Wagon Kilns.

As part of the visit, producers will participate in a workshop where the manufacturers and builders of the furnaces will present their technologies to the delegates.  This would be an opportunity for the producers to speak directly to the manufactures and gain first-hand knowledge. An English speaking translator will be provided.

Mission Details

  • Scheduled Dates:        26 – 29 April 2016
  • Places to be visited:    Seridó and Assu, Brazil

We understand that this event coincides with the Clay Brick Association’s Annual General Meeting and thus many will not be able to participate.

For logistical reasons interested brick makers are to contact John Volsteedt by Wednesday 2 March.

* Brick makers will be required to pay for their own travelling costs.

CEDAN KILN - semi-continuous moving fire

This kiln is an alternative version of the traditional Hoffman model and consists in a set of chambers (usually twelve to sixteen chambers) built in pairs to facilitate the flue gases transfer.

The heat produced in a chamber is deflected to the dome (roof ), then the hot gases move down heating the bricks and leave the chamber through the openings on the floor, move across the openings in the floor and to the next chamber through holes at the bottom zone in the fixed walls which are connected to the next chamber, producing a preheating of this chamber.

This kiln produces homogeneous products due to the constant temperature of the heat that moves from one chamber to another, with a low level of losses.


The Mobile Tunnel Kiln is a model in which the entire structure of the kiln can be moved using a rail system and stacked over the green bricks previously loaded for burning. The burners are coupled along the side of the kiln.

The structure of this kiln is very lightweight, because it only uses ceramic fiber and steel layers. Fuel can be use biomass, gas or oil.
