Air expander is one of the key components in a CAES system because its operational characteristics determine the power conversion efficiency and the power
Compressed air energy storage (CAES), an energy storage system, consists of three key components: compressor, storage space and expander. During charging phase, the
In terms of storage types, the dominant advantage of lithium-ion batteries continues to expand, accounting for 97.4% of the new type storage installation. Other types, such as air
The potential energy of the compressed gas is transferred to mechanical energy of the shaft. In the expander, the timings of opening and closing the intake and exhaust valves can be controlled. For example, the intake valve of the expander opens when air reaches sufficient pressure in the cylinder.
Available in configurations to perfectly match your specific application requirements, the expander generators drive electrical power production from industrial processes and sustainable resources.
For CAES systems, reciprocating expanders are appropriate for micro-scale and small-scale systems. In these scaled-down CAES systems, especially for micro-scale systems, because of the low storage capacity and low flow rate, relatively high pressures are usually necessary to increase the energy and power density.
Power generation extends up to 25 MW per expander stage, with up to two stages per expander. Our variable inlet guide vanes (IGV) provide accurate process control over a wide operating range, avoiding the energy loss associated with inlet throttling control
The expander is the key core component of the compressed air energy storage system, and poses numerous technical challenges, such as high load, large flow, complex flow and heat transfer coupling, and varied working conditions.
Expanders: working principle, modelling approach and machine selection Expander, in general, operates in a reverse process of the same type compressor. Various types of compressors are used in a wide range of applications, from fridges to rocket engines. These compressors have significant impacts on the prototypes of expanders.
