Fin Tube Heat Exchanger in WHRS Power Plant

Waste Heat Recovery System(WHRS), or Wastewater Heat Recovery System(WWHRS), becomes a real sensation as the world is currently in a campaign of advocating environmental protection. JIEMA responds to the call and had already helped millions of Companies at home to perfect their Waste Heat Recovery Line. And now, we are ready to assist a million more.

Jiema Fin Tube Heat Exchanger in WHRS Power Plant is characterized by compact structure, nice appearance, easy installation and management and high durability. It is applicable to the heating based on centralized air supply and local heating and other purposes as well.

⛆ Installation requirements of Our Fin Tube Heater in ORC Heat Recovery

1. Before installation, inspect whether the heater is intact and screw off the pipe clamps and the plugs.

2. Connecting the connection tubes (water tube and steam tube) with the same size as connectors of the heater’s inlet pipe and outlet pipe. Do not support the heater with the connection tubes.

3. Equip a corresponding heat medium pipe system for our Fin Tube Heat Exchanger according to the architectural design. Gate valves should be installed on the steam pipe (or the hot water pipe) and the return water pipe; a condensed water drainage device should be installed on the condensate water pipe. When multiple air heaters are used at the same time, particularly when air is in a serial connection state in the air flow, it would be best that each can control its air inlet device, air outlet device and return water pipe device.

4. When the air inlet pipe of the Finned tube air heat exchanger is in direct connection with an outdoor place, a blocking device should be arranged at the air inlet to avoid damage of the air heater due to freezing when it is not in service.

2) Install a steam trap at the end where the return water connection tube is and make sure its displacement is larger than three to four times of the condensate water volume of the air heater.
3) Feed steam about ten minutes before the fan is started to preheat the Fin Tube Heat Exchanger to avoid impact on the equipment by a lot of condense water as a result of sudden entry of steam into the cold air heater.
