Reducing valves: -the line allows to test two different reducing valves -each reducing valve has a stop valve before and after and a Y shaped filter -two different technologies are used (pilot operated pressure reducing valve and direct acting reducing valve) -a third line with a valve allows to bypass reducing valves Control valves : -the line allows to test two different control valves -valves control the steam flow, depending from the water temperature at the outlet of the exchanger - each control valve has a stop valve before and after and a Y shaped filter -there is an electric actuator and a mechanical actuator -a third line with a valve allows to bypass control valves Steam condenser : -the exchanger is tubular type and is cooled with water -the cooling power is designed to fit with the maximal steam flow generated by the boiler (about 130KW) -it is equipped with temperature sensors on the different circuits -it is equipped with a water flowmeter -it includes a vacuum breaker to avoid degradation when the steam condensates -condensates go to steam traps Steam traps : -the line includes five steam traps -each steam trap consists in a different technologie (thermodynamic, inverted bucket, bimetallic, ball float and balanced pressure) -each steam trap is equipped with a sight glass and stop valve -condensates go back to the water tank Water cooling circuit : -Cooling unit outside -the cooling circuit includes a centrifugal pump -Cooling unit : -Average power : 140KW -local electric cabinet with emergency stop -fans are controlled by a temperature switch -the structure is corrosion resistant -fans are protected -stop valves on the outlet and inlet -drain valve Others characteristics : -the equipment include a pump (operated by steam) for condensate return -the equipment also include a blowdown tank. -the equipment will be fitted to laboratory |
