One Mean Green Machine
Generator range powers higher output of waste heat-to-power; available in three configurations
ElectraTherm, specializing in distributed power generation from waste heat, has released its largest output machine, the Green Machine 4020.
The company said the Green Machine 4020 accepts higher input flows and can run in combined heat and power (CHP) mode where exit condensing temperatures are sufficient to feed district heating systems or industrial processes. The unit can pair with larger reciprocating engines sized greater than 800kW to increase both power output and efficiency, and opens market opportunities in natural gas compression and processing, ElectraTherm said.
Hot water enters the machine between 77 to 116°C and flow rates between 6.4 – 22.1 L/s, where it heats a working fluid into pressurized vapor. As the vapor expands, it drives a patented twin-screw power block, which spins an electric generator and produces up to 110 kWe. Organic Rankine Cycle (ORC) condensing heat can be further utilized to supply 50-55°C water to local heating loads.
The Green Machine 4020 comes available in three configurations: a stand-alone Green Machine ORC at 2.4 x 1.8 x 2.2 m for the smallest footprint; a 6 m ISO frame for ease of installation and multiple condensing options; and the last turnkey package is available for plug and play installation and includes a liquid loop radiator, all piping/pumps and minimal engineering in a 12 m ISO frame.
