Screw Expansion Power Generation Device

As an efficient waste heat recovery solution, our screw expansion power generation device comes in two types, including ORC type and steam type. Different power generators can be driven by different kinds of heat sources. More featrures and detailed parameters are detailed below. Welcome to contact us if you have any questions.

1. Wide heat source range

Our screw expansion power generation device can work on various kinds of heat sources including superheated steam, saturated steam, mixture of water and steam, hot water, and many other hot fluids. Thus the waste heat can be utilized to a great degree.

2. Stable performance
The screw expansion power generation device can still work stably when the heat load and other parameters fluctuate drastically (10%-120%).

3. Low maintenance
This machine can work for 10 years with limited overhauls. The installation, moving, small scale maintenance and daily operations are quite simple and convenient. No disturbance will be produced onto the original system.

4. Asynchronous generator
An asynchronous generator is adopted for our screw expansion power generation device, so the electricity can be delivered to the factories trough the company's power grid. No negative influence will be produced onto the original power supply quality. If any emergencies occurred to the power machine, the safety protection device of generator system will be activated and disconnect with the power grid, ensuring the safety of the power grid and power generator.

The suitable heat sources for different generators have been detailed if the form below.

Model Usable heat source
ORC type Low pressure steam Hot water

1. Hot water (higher than 80℃)
2. Hot fluid like oil and chemicals (higher than 80℃)
3. Saturated steam
4. Low pressure steam
5. Smoke
6. High pressure steam
