ElectraTherm Green Machine Operates on Incinerator Waste Heat in Czech Republic
Green Machine ORC Fleet Surpasses 25 Years of Operational Run Time.
- (1888PressRelease) July 10, 2014 - ElectraTherm, a leader in distributed, waste heat to power generation, installed a Green Machine at an incineration plant in Jihlava, Czech Republic. This is the first incinerator application using ElectraTherm's Organic Rankine Cycle (ORC) technology. ElectraTherm and its Czech distributor, GB Consulting, commissioned an ElectraTherm Green Machine in November 2013 to generate renewable energy on site. The machine is utilized on an as needed basis in conjunction with waste elimination and has accumulated over 1,000 hours. To date, ElectraTherm's installed base has surpassed 210,000 hours of runtime (more than 25 years) with 41 machines in the field.
The Green Machine 4400 is ElectraTherm's standard ORC generator with electrical output up to 65kWe. In Jihlava, the Green Machine feeds off the excess hot water from the site's medical waste incinerator to generate green energy from heat that would otherwise go to waste. In addition to the Green Machine, excess heat from the incinerator also feeds the site's district heating system.
At the site, ElectraTherm's ORC technology begins with hot water entering the Green Machine at 75-90°C at 10 l/s, where it heats a working fluid into a pressurized vapor. The high pressure vapor expands through ElectraTherm's patented twin screw power block, spinning an electric generator to produce power. After turning the expander, the vapor is condensed back into liquid through the use of a liquid loop radiator.
ElectraTherm's Green Machine generates fuel-free, emission-free power from low temperature waste heat, on applications such as internal combustion engines, biomass, geothermal/co-produced fluids and solar thermal. A list of reference sites is currently available on the website.
