TEIDE REFRACTORY SOLUTIONS, S.L., DESIGNED KILN CARS ADAPTED TO YOUR RAMP TEMPERATURE

The Technical and Simulation departments of TEIDE REFRACTORY SOLUTIONS, S.L., is strongly committed with the optimization of our customers’ kiln cars.

¿Each ramp has its optimal kiln car?

Yes. In previous posts we explain the phenomena of heat transfer of that occurrs inside the furnace and how TEIDE REFRACTORY SOLUTIONS quantify the heat losses.

As a general rule, the higher kiln car is, the lower the heat loss is.

In addition, we have seen that taking into consideration the kiln car tunnel as a heat exchanger, in the second section of it occurs a partial recovery of the load and heat.

This heat recovery will be higher or lower depending on the temperature ramp. In TEIDE REFRACTORY SOLUTIONS, we know the importance of an optimized design for each customer, to offer optimized solutions to your needs.

To equality of conditions, a higher kiln car requires a bigger initial investment by the customer. At TEIDE REFRACTORY SOLUTIONS we know that a detailed study of the return on investment is essential to decision-making.

An example: what is the optimal height for a ramp of 20 hours? And a ramp of 40 hours?

In a previous entry we quantified with HEATEIDE® the losses by sensitive heat and kiln car for a cycle of 20 hours. Repeating the same numerical simulation for a ramp of 40 hours, we get the following matrix results:

Matrix results obtained with HEATEIDE®

In the matrix of results obtained with HEATEIDE® for a ramp, furnace and technology set it can be observed that:

For the ramp for 20 hours, consumption by sensible heat and kiln car especially decrease between 200 mm and 300 mm, being 20%. Between 300 mm and 500 mm, the savings are lower, and the increase of savings does not justify the increase of height of the kiln car. In this case, for a 20-hour temperature ramp, the optimum height is 300 – 350 mm.

On the other hand, for the ramp of 40 hours, consumption by sensible heat and kiln car especially decrease between 200 mm and 450 mm, being more than 40%. Between 450 mm and 500 mm, the savings are lower, and the increase of savings does not justify the increase in height of the kiln car. In this second case, for a 40-hour temperature ramp, the optimum height is 350 – 400 mm.

A detailed study with HEATEIDE® for your ramp and your needs, will serve to detect opportunities of optimization.
