ABSTRACT
Energy efficient
plant operation is the most important research area in the industrial energy
sector. The use of various methods such as pinch technology, reduction of
frictional losses can reduce energy consumption to a considerable extent. The
use of nonconventional energy is also becoming more and more important. Proper
insulating material in construction and industrial sector can avoid energy
losses to considerable extent. Current review summarizes research and studies
on insulation.
Key
words: Energy
saving, heat losses, insulating materials.
Sustainable
development is becoming the important and most widely used terminology in
modern day engineering. Energy and environment are two pillars of sustainable
development. The research carried out in environmental engineering sector
strives for treatment of industrial wastewater to removal various pollutants
from it such as organic matter, heavy metals and biological impurities.[1-5] Also water treatment includes the reuse
and recycling of water.[6-8]
Energy is required for all the industrial
operations in manufacturing and nonmanufacturing sector. Major industrial
equipments such as boiler, cooling tower, refrigerators, heat exchanger need
energy. Attempts have been made to optimize the energy requirement in these
equipments.[9-12]
Use of non conventional energy such as
wind, tidal and solar energy is being explored with moderate to high success.[13,14]
Other measures such as
application of pinch technology, reduction of friction losses can add energy
effectiveness of a plant.[15,16] Nonconventional energy resources
are becoming important day by day.[17] Proper insulation can prevent the
wastage of energy and render economy to the plant operation. The current review
summarizes research carried out on types and applications of insulation.
Zach
et.al. carried out studies on development of thermal insulation plasters.[18]
They used this insulation for
insulating and sanitation of building constructions. According to them, thermal insulation of outer structures of
buildings is an issue that is often closely associated with moisture sanitation
and recovery. In their paper, they described the results of research that is
oriented toward the development of ultra-light thermal insulation plasters on
silicate base. They observed that lightweight plaster mixtures which are
based on lightweight aggregate of obsidian and lime hydrate show a very good
ratio of thermal insulating and mechanical properties. It was also proved
during the investigation that fly-ash is a suitable alternative substitution
for metakaolin. Inorganic heat
insulation panel based on sepiolite nanofibers was studied with respect to
preparation and performance by Wang et.al.[19]
They developed energy saving
panel materials containing sepiolite nanofibers by means of the synergistic
action of inorganic adhesive, curing agent, and hydrogen peroxide. They used
sodium fluorosilicate as curing material and sodium silicate as inorganic
adhesive. They observed that the synergistic action of inorganic adhesive,
curing agent, and hydrogen peroxide enhanced performance of thermal insulation energy saving panel
materials. Heat transmission and external forces were effectively arrested by
these materials. Swinton et.al. studied performance
of thermal insulation on the exterior of basement walls.[20] They observed that only small
differences were found among the different products in their ability to provide
sustained thermal performance. According to these studies, it is very important
to avoid even limited contact with another thermally conductive element, such
as concrete. It can have a significant impact on the thermal performance of the
entire basement wall system. According to them, exterior insulation can provide
a first line of defence for the basement envelope system if it has sufficient
water management capability. Hopper evaluated the installation of retrofitted
external wall insulation.[21] He presented an overview of an
evaluation of the installation of retrofitted external wall insulation (EWI) at
existing dwellings in Swansea. Their studies were concentrated on identifying
the occurrence of potential thermal bridges as these can undermine the overall
effectiveness of the EWI. According to them, thermal bridging can lead to
internal condensation on the walls and ceilings. This can pose health problems
for occupants. Garber-Slaght and Craven studied window
insulation for cold climates.[22] According to them, it is necessary upgrade or insulate windows in order to improve the
thermal envelope of a home. In the area of long summer season, it becomes
uneconomical to change the window. It is always envisaged to have an insulation
system which is cheaper and convenient. Ability of
homeowners to frequently move or maintain window insulation plays important
role in windows insulation system. Hebner studied electrical machines in
electric ships with respect to insulation.[23]
The standards provided, according to
them cannot guide the effective insulation system. According to them, there is
a need to specify the electrical, thermal and mechanical environment that a
ship power system will experience. Zach et.al. studied alternative thermal
insulations based on sheep wool.[24] According to them ship wool has many
advantages such as no health risk, easy to renew, easy to recycle, high
hygroscopic nature etc. They carried out tests under frequently occurring and
strict climatic conditions. They concluded that sheep wool is an excellent
acoustic insulating material.
Proper
insulating material can make the construction and operational activities energy
efficient. Heat losses can be minimized by using proper insulating materials. Thermal insulation of outer structures of
buildings is an issue that is often closely associated with moisture sanitation
and recovery. The synergistic action of inorganic adhesive, curing
agent and hydrogen peroxide enhance performance of thermal insulation energy saving panel
materials.
