1.1 Planning and preparation
The design of a suitable insulation system for
industrial installations is a major factor for its
economical operation, functionality, security,
durability and environmental impact. Additionally,
the installation-specific heat losses are specified
for the entire life cycle of the plant. Corrections at
a later stage, such as subsequently increasing the
thickness of the insulation, for example, may no
longer be possible due to lack of space. Correc-
tions at a later stage may also entail a far greater
investment compared to the original planning.
Continually rising energy costs are also often
overlooked factors when dimensioning the
insulation. Insulation thicknesses that are
designed to last take energy price increases into
account. They form an important criterion for the
economical operation of the installation after just
a few years.
Properly dimensioned insulation systems
constitute an important contribution to
environmental protection, carbon dioxide (CO²)
reduction and to economic success. CO² reduction
is also an economical operation, as it lowers the
costs for CO² emission certificates.
Nowadays, conservational and economical
operations are no longer conflicting ideas, but are
two inseparable parameters.
1.1.1. Decision criteria for the design of
an insulation system
Selecting a suitable insulation system depends on
the following five parameters:
1. Functional requirements
a. Object dimensions
b. Operation of the installation
c. Operating temperatures
d.
Permissible heat losses or temperature
changes of the medium
e. Frost protection
f. Ambient conditions
g. Maintenance and inspection
2. Safety aspects
a. Personal protection
b. Fire protection
c. Explosion prevention
d. Noise reduction within the plant
3. Economics
a. Economical insulation thickness
b. Pay-back time
4. Environment
5. Corrosion prevention
