5 Optimisation project n°3: Improve steam ancillaries insulation

5.1 Current situation

Not only for safety reason, must hot surfaces have effective insulation to

prevent excessive heat loss by radiation. The basic function of insulation

is to retard the flow of unwanted heat transfer. There is more chance of

part of steam to condense during distribution if the pipelines are not

properly insulated.

There is a closely interrelated efficiency between boilers and their

distribution systems. The losses occurred in the distribution systems have

a significant impact on boiler operations. When these losses are minimized, boiler plant efficiency is

improved.

We observed some valves and filters on steam lines which are not insulated in your steam

distribution system.

The following table shows the non-insulated equipments identified during the audit:
