2008-8-16 · A refinery in Northern California was unable to meet its desired boiler feed water silica specifications on a consistent basis. The higher silica levels led to an excessive blow down requirement in the boiler system. The higher blow down rates were significantly affecting the refinery's water

2012-11-30 · used to produce purified water for 'NOx' control within a power station. 2.0 RAW WATER The raw water supply is as SW-I, which can have some organic and colloidal contamination, and for some oils, fats and greases. 3.0 TREATED WATER QUALITY The treated water requirement is RO/EDI water to a conductivity of <1 micro siemens

Minimize boiler blowdown and save water and energy. Blowdown of steam boilers is necessary to comply with the specifications of the boiler suppliers as to the contents of salt (specific gravity) and the alkalinity (P-value) in the boiler water.

Total not to exceed 1.5 parts per million in boiler feed water. Copolymer cont more than 0.5 percent by weight of acrylic acid monomer (dry weight basis). As defined in ? 172.820 of this chapter. Total not to exceed 1 part per million in boiler feed water (calculated

Depending upon this analysis, various pretreatment methods may be employed to prepare makeup water for your boiler feedwater system. Maintaining appropriate feedwater temperature and boiler feed water quality will help to ensure the boiler remains safe, operational, and failure-free for many years of service.
