ADCA FLASH CONDENSING HEADS FCD DESCRIPTION AND OPERATION The ADCATherm flash condensing heads are designed to promote energy efficiency on new or existing systems. Mixing the flash steam with the boiler make-up water allows the energy within the flash steam to be fully absorbed into the water and therefore reduces energy waste that normally occurs from the discharge of flash steam through a vent. The main advantages over some traditional systems are that it is possible to make most of the piping connections in a single and compact mixing unit and a greater heat recovery efficiency can be achieved. This mixing unit includes the following fluid connections: -Cold make-up water; -Condensate return; -Re-circulating feedwater; -Vacuum breaker and vent connection; -Optional connections for flash steam from a TDS (Total Dissolved Solids) heat recovery system. The mixing unit includes the necessary baffles, spray nozzle, water injector pipe, etc., in order to guarantee the high mixing energy efficiency. The water is finally mixed in the vessel as it passes through an immersion tube, which ensures a quiet operation. The feedwater is re-circulated using a low power re-circulating pump which will improve thermal efficiency by reducing the temperature stratification. Additional equipment can be used to improve energy efficiency and accurate control. ADCATrol control valves, steam injectors, exhaust heads and many other items are available from an ADCA supplier. Since each plant has particular requirements we suggest that a local ADCA distributor is contacted for layout discussion and equipment selection. MAIN FEATURES Prevents energy wasting.
