Product Profile of Blowdown Heat Recovery Units
Blowdown Heat Recovery Units is offered by Forbes Marshall which is an ISO 9001 certified company. The Blowdown Heat Recovery System comprises of:
- Ball Float Trap at water outlet of Flash Vessel
- Thermostat and Circulation Pump for Soft Water
Steam boilers need to be blown down to control the level of total dissolved solids [TDS] in the boiler water. This is achieved by using a TDS control system which will open a valve to allow boiler water to discharge, when the TDS level rises above a pre-set limit. Relatively low TDS Feedwater then replaces the discharged boiler water. Up to 80% of the heat in this discharged boiler water can be recovered with a properly designed heat recovery system.
User benefits of Blowdown Heat Recovery Units:
- Can recover up to 80% of the heat from blow down
- Reduces expensive treated make-up water by recovering flash steam
- Rapid pay-back time from complete system package
- Flash vessel designed and constructed to BS 5500 Category 3 for enhanced safety
- Stainless steel heat exchanger plates can be removed for examination without disturbing pipe work
- Reduces temperature of blow down water for safer disposal
Thus, the Blowdown Heat Recovery Units ensure zero wastage of heat from blowdown operation and results in saving of fuel in the boiler firing. The Blowdown Heat Recovery Units is designed to the specific blowdown and feedwater parameters varying on plant to plant basis.
