TEIDE REFRACTORY SOLUTIONS OPTIMIZES THE HEIGHT OF THE KILN CARS

The Technical and Simulation Departments of TEIDE REFRACTORY SOLUTIONS S.L., have the strong commitment to optimize the kiln cars of our customers.

¿What kind of heat transfer processes happen inside a tunnel kiln?

Each tunnel kiln installation is unique. A detailed study then is necessary to know the distribution of the different heat transfer phenomena. As an example the following graph summarizes distribution of various thermal phenomena that occur in a particular tunnel kiln..

TEIDE REFRACTORY SOLUTIONS, S.L., offers high quality kiln cars that minimize sensible load and kiln car losses

¿Which height should have my kiln car?

A too low kiln car transfers too much heat through the bottom. On the other hand, a too high kiln car unnecessarily reduces the height of its load with the consequent lower productivity.

TEIDE REFRACTORY SOLUTIONS has got the answer

TEIDE REFRACTORY SOLUTIONS, S.L., uses numerical simulation implemented in HEATEIDE® to calculate the energy consumption of the kiln cars during the project phase.

As an example, under these lines is shown the temperature distribution inside different kiln cars with different heights under a firing process with the same temperature ramp.

Temperature distribution in different heights of the kiln car: 200 mm, 350 mm and 500 mm. Afterwards the information obtained from the numerical simulation is analyzed with our costumer.

The thermal behavior of every solution can be compared (as detailed in the previous post http://www.teiderefractories.com/en/blog/teide-refractory-solutions-quantifies-the-exchanges-in-its-tunnel-kiln/ )

Energy consumption and heat flux for a kiln car design of TEIDE REFRACTORY SOLUTIONS. The following table shows the energy consumption of different kiln cars with different heights under the same 20 hours temperature ramp.

  • Energy consumption of the kiln car for different heights of it, in a temperature’s cicle of 20 hours.

  • That is how TEIDE REFRACTORY SOLUTIONS, S.L. get optimized designs for our customers: more efficient, more economical and more sustainable.
