Continuous Blowdown Heat Recovery System for Boiler Surface Blowdown.
Most boiler manufacturers and water treatment companies recommend boiler water TDS be maintained at certain levels. The purpose of continuous blowdown is to continuously take boiler water from 4"-6" under the surface where the TDS is at its highest concentration so that it can be replaced with fresh water. While continuous blowdown is the best way in controlling these solids in the boiler the heat lost to drain over time can be tremendous. Penn Continuous Blowdown Heat Recovery Systems can recover 90% or more of this heat normally lost. Two stages provide the heat recovery.
