Flash Steam

Heat Exchanger with Flash Cooling and Active Drainage

Recovering energy from condensate using a flash cooler.

Part	Component	Function
1	Separator	to protect the steam make-up valve from wet steam
2	Isolation Valve	to isolate the installation from the steam supply
3	Strainer	to protect the control valve from detritus
4	Self-acting Control Valve	to regulate the steam flow to the heat exchanger
5	Check Valve	to prevent the ingress of air into the condensate system
6	Temperature Controller	to sense and control the heater outlet water temperature
7 - 12 inc.	Separator Steam Trap Set
13	Air Vent	to vent air from the condensate system
14	Isolation Valve	to isolate the heat exchanger from the flash vessel
15	Strainer	to protect the heater float trap from detritus
16	Check Valve	to prevent the pump steam supply trap from backflow
17	Isolation Valve	to isolate the steam trap set from the flash vessel
18	Ball Float Steam Trap	to drain the heat exchanger of condensate
19	Sight Check Valve	to prevent condensate backflow
20	Flash Vessel	to separate the flash steam and condensate from the heater
21 - 24 inc.	Pump Steam Supply Steam Trap Set
25	Isolation Valve	to isolate the pump from the steam supply
26	Check Valve	to ensure directional flow through the pump
27	Condensate Pump	to pump condensate from the receiver
