Chapter 13 Boiler Blowdown Control | SUE

Heat recovery is used frequently to reduce energy losses that result from boiler water blowdown. Figure 13-2 illustrates a typical boiler blowdown heat recovery system using a flash tank and heat exchanger. Installation of heat recovery equipment is valuable only when energy from the flash tank or the blowdown water can be recovered and utilized.

capital cost is much lower for a single waste heat boiler system with high utilization than for multiple boilers connected to localized DFTOs. Waste heat boilers for localized DFTOs must be designed and sized for the peak flow and heat load from each oxidizer but will normally operate at just a fraction of that design capacity.
