A decrease of 1.1°C in water temperature results in extra production per hour. The cost of rebuilding cooling tower can be more than paid because increased production creates extra product sale.
It’s a myth that every cooling tower
can be rebuilt. Rebuilding a cooling tower does not ensure the return more cooler
water or save power or money. Each cooling tower installation must be treated
on individual basis i.e. thermal, hydraulic and aerodynamic calculations of
existing conditions should be studied by a cooling tower service provider or
engineer to see where improvement can be anticipated. Customers can also
include their cooling tower testing requirement in the contract.
A cooling tower service provider or
engineer can perform a thermal test before and after rebuilding cooling tower. The
cooling tower service provider or engineer should provide a report mentioning reasons
of the cooling tower's deficiency along with their solutions. In addition to
capability percentage the report must include cooling tower specifications along
with the estimated budget required to correct the deficiency.
Organizations can be conducted
in-house thermal testing for a close estimate. However, a competent cooling
tower operator can tell by production results if cooling tower cold water is
adequate or not. Allow a competent cooling
tower engineer with approved instrumentation to handle it. Only a certified test
will provide the capability percent at which the tower is operating, compared
to the 100% for which it was purchased.
Due to the
added cost of new ba-sin, piping and wiring, rebuilding and retrofit should be
considered. The expense of retrofitting and rebuilding a cooling tower to
upgrade its capacity or capability has a rapid payback if the proper investigative
engineering is performed. The points mentioned above are few and far
between, but good care and attention can help to identify them.
