ElectraTherm Green Machine Operates on Incinerator Waste Heat in Czech … – Newswire Today (press release)

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.

Recuperating waste heat under the hood – Phys.Org

In spite of the efforts of automobile manufacturers, nearly 70% of the fuel consumption is dissipated as heat into the environment. The problem is that the temperature of the waste heat is too low to be converted in a useful manner. However, there is a thermodynamic system that can exploit these differences in temperature to produce electricity: the Organic Rankine Cycle (ORC). It’s currently only used in recuperating industrial heat (in cement production), biomass production and geothermal energy applications. The ORC operates similarly to a steam engine, except that the water is replaced by organic fluid such as propane. Pumped within a hermetically sealed circuit, the fluid is heated and evaporated, then passed through a turbine, then condensed back into liquid form to start the cycle over again.
