Cleaver-Brooks Blowdown Separators

Boilers that supply steam for power, process or heating applications require periodic and more often, frequent, blowdowns to prevent buildup of harmful solids. Blowdown protects boiler surfaces from severe scaling or corrosion problems that would otherwise result. Cleaver-Brooks blowdown separators use a safe, economical flash purification process for enhancing blowdown effectiveness.

Steam is rapidly separated from blowdown water and vented out the top of the blowdown separator in a cyclonic spinning action. Water and dissolved solids are flushed out the bottom drain.

The design is quiet, with noise levels held below 90 dBA, so no exhaust head is required. Internal pressures do not exceed 5 psig. Blowdown water is cooled to 120 °F by a drain tempering device, designed to meet state and local codes. Cleaver-Brooks blowdown separators are compact, and can be quickly installed with few connections. Accessories include leg or wall brackets, drain tempering fitting, strainer, temperature regulating valve, thermometer, pressure gauge and flanges.

Continuous boiler surface blowdown is the most effective method of purging destructive solids from any steam boiler system. However, this protective procedure also results in a constant and costly heat loss, unless a blowdown heat recovery system is used. Cleaver-Brooks blowdown/heat recovery systems adjust automatically to changing system demands, and recover 90% or more of the heat normally lost during boiler surface blowdown operation. The blowdown/heat recovery systems will usually result in a payback in a few short months from fuel savings alone.

The Cleaver-Brooks Packaged Blowdown Heat Recovery System serves two primary functions:

1. It automatically controls the surface blowdown to maintain the desired level of total dissolved solids (TDS) in the boiler, reducing the amount of blowdown to a minimum.
2. It recovers the heat from the high temperature blowdown, and transfers it to the incoming cold make-up water, maximizing boiler efficiency. Use of BHR also improves deaerator efficiency by reducing surges caused by adding large amounts of cold make-up water to the system.
