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. The volume of blowdown is determined by the boiler type, operating pressure and water treatment quality of feed and makeup water.

In high quality boiler water, levels of suspended and total dissolved solids (TDS) are down to a minimum. This will minimize blowdown volume and hereby reduce energy loss, as the temperature of the blowdown liquid is the same as the steam generated in the boiler. Lower blowdown rate will also reduce makeup water and chemical use, saving you money and water.

High quality boiler water

Steam has a very high heat capacity and is essential in process industries, production of heat in district heating or for high-pressure turbines that generate electricity in heat & power plants.

High quality boiler water is vitally important to extend the life cycle of pipes, boilers and heat exchangers and ensuring ongoing performance and operational reliability.

Optimal treatment of boiler water removes impurities in the feed water, which reduce:

• Corrosion and thus boiler wear
• Frequency of blowdown
• Energy loss
• Consumption of chemicals
• Scaling
• Carryover

The boiler water treatment system

The best solution is always based on individual needs and the quality of the raw water available, in relation to the quality of the feed water needed for specific boiler use.
