HEAT RECOVERY SYSTEMS
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 Crossover or Shell & Tube Continuous Blowdown Heat Recovery Systems can recover up to 95% of this heat normally lost. Two stages provide the recovery. The first stage uses a Penn Flash Separator where the high pressure condensate flashes to a low pressure steam use such as a feedwater heater or deaerator. The second area a separate heat exchanger that transfers the remaining heat to boiler Make-up water.
