An optimal cooling system is mandatory to maximize the
production of a power plant.
System stresses are significantly reduced through effective
water treatment by controlling and limiting corrosion, scale, fouling and
microbiological contamination. Ensuring that the cooling water system maintains
the correct temperatures is also key.
Through such control, further advantages include:
Increased overall efficiencies
- Limited loss of heat transfer
- Reduced maintenance costs
- Reduced power costs
- Equipment repair or replacement cost savings,
lending to a reduction in shutdowns
With cooling towers, slime grows rapidly in the system, which
can block free water flow and become a hazard for water quality. The slime,
which often grows in condensers and on cooling surfaces of re-circulating
systems, can significantly reduce efficiency. Undesirable slime and biofouling
in spray ponds that supply such cooling systems and cool boilers may also cause
severe problems for the site or facility, including cooling efficiencies that
can be compromised due to flow and pressure restrictions.
Lonza’s extensive range of oxidizing and non-oxidizing biocides,
bio-dispersants and halogen stabilizers are addressing the need to control
microbiology in both closed and once-through cooling systems of power plants.
Calcium Hypochlorite, Dantoin® BCDMH, and Dantobrom®
(proprietary blends of
halohydantoins) oxidizing technologies are well suited for the pre-treatment of
the raw water.
