UHPC thermCombi lining system consists of a highly effective insulating layer and UHPC
wear protection.
For a cement plant in Europe, we should
create a technically optimal possibility thata complicated hot gas line is provided with
wear protection against a very abrasive
material and at the same time the gas
temperature must not drop below 700°C /1292°F. A similar project we had years ago
for asteel plant in Asia.
In order to meet these customer requirements,we have chosen a UHPC thermCombi lining
system.
We reduced the temperature for the steel
structure to 80°C / 176°F. That was no problem
with the insulation material we chose. A high
temperature resistant UHPC wear protectionlayer was installed on the insulation layer.
The advantage over a traditional refractory
lining was:
- The combination lining was about 60% lighter
in weight.
- The total layer thickness of the combination
lining was 400% less than that of a standard
refractory solution.
- This meant that the steel pipe diameter was
much smaller than with a refractory lining
and the supports had to carry much less weight.
- UHPC HT wear protection can withstand
temperatures of 1200°C / 2192°F, which was
an additional security in this project.
- UHPC HT wear protection is several times morewear-resistant than refractory concrete, which
has resulted in a significantly longer service life
and much less maintenance.
