    Calculate the blow down rate using the formula for total dissolved solids (TDS) in the feed water and boiler which are equal to 250 and 4,000 ppm respectively. Use a design pressure of 0.2 barg for the flash vessel. See the Spirax Sarco Boiler Blowdown heat Recovery System data for typical installation. Use plate heat exchanger type HE for the

    Continuous blowdown of water is necessary to keep water impurities to optimum level but this also lead to heat losses, so in order to reduce the heat losses, it is important to check the number of blowdowns to be done in a day as well as this heat from water can be recovered by installing blowdown heat recovery system for preheating water or

    The amount of blowdown should be minimized by following a good water treatment program. Installing a heat exchanger in the blowdown line allows this waste heat to be used in preheating makeup and feed water. Heat recovery is most suitable for continuous blowdown operations which in turn provides the best water treatment program.

    Recover Heat from Boiler Blowdown Heat can be recovered from boiler blowdown by using a heat exchanger to preheat boiler makeup water. Any boiler with continuous blowdown exceeding 5% of the steam rate is a good candidate for the introduction of blowdown waste heat recovery. Larger energy savings occur with high-pressure boilers.
