Technology
The Rankine steam power cycle is superior all other known power cycles when it comes to the use of different types of energy sources. I.e., solid, liquid and gaseous fuel, nuclear, solar energy and waste heat from other power cycles. Contemporary steam power is mostly embodied as large, centralized power plants utilizing steam turbines (nuclear and other power plants).
However, when implemented as a piston engine coupled with modern, high performing components in a steam engine system, it is possible in a small-scale and decentralized way to realize multi-energy sources for stationary as well as mobile applications.
EXPANDER
and steam generator
The RANOTOR steam engine is a multi cylinder axial piston engine expander for vibration free operation and with a smooth output torque. The piston expander, with it's active sealing element, enables an almost complete expansion of the steam even at low rpms.
RANOTOR has developed a compact steam generator that together with the steam engine forms a package that has higher power density (kW/kg, kW/litre) than any comparable internal combustion engine.
CHP
Combined Heat and Power
The modern steam engine offers a cost effective multi-energy small scale CHP (Combined Heat and Power) for local and decentralized electricity and heat production in the power output range of 10 – 1000 kW.
A integrated thermal energy storage enables the storage of cheap electricity from the grid when the price is low. It can also handle short power surges.
