ZCW hot water dispenser
Purpose
Dispensers accumulate usable hot water in district heating substations with flow heat exchangers.
System that uses hot water dispenser allows usable hot water equalization within the range of ą 3 oC in relation to demanded temperature. Usable hot water temperature stabilization consists in mixing water of different and rapidly-changing temperature parameters. Dispensers prevent thermal stresses from occurring in installation stacks, especially in high buildings and liquidate thermal stresses of direct-activity thermoregulators.
Technical Description
Hot water dispenser is a vertical container of cylindrical shape of Dn 800mm diameter closed with two ellipsoidal heads.
In container's upper head there are two vertical, flanged Dn A spigots. Supplying spigot reaches with its cut end (45o angle) to container's lower part, while the other one is outlet spigot.
Supplying spigot is marked with arrow that shows direction of flow.
G1" technological spigot for thermometer's installation and G2" technological spigot are also located in upper head.
Existing spigots may be modified and changed on Customer's individual request.
In lower head G2" technological spigot is also located; it acts as blowdown - washout connection.
Two G1\" spigots for thermoregulators' connection and two G1 1/4" spigots for circulating pumps' connection are located in a boiler drum.
Whole construction of the stabilizer is protected against corrosion with zinc coating.
