ORC - "Green machine" - electricity from waste heat

ElectraTherm's Waste Heat to Power Generation System

ElectraTherm's Green Machine converts low temperature water flows into fuel-free, emission-free electric power. The Green Machine output range is from 20 kWe to 65kWe, based on temperatures and flows. The performance table below shows our heat and flow parameters. Or, review our brochure here.

Stationari engines


Stationary engines

ElectraTherm technology captures the waste heat produced from internal combustion engines. Using the waste heat available in the engine jacket hot water, engine exhaust or a combination of both, the Green Machine captures the waste heat and converts it into electricity. ElectraTherm’s technology can be applied to internal combustion engines used for gas compression, pumping, power generation, combined heat and power generation, and irrigation.

 

boilers waste heat


Boilers or Process waste heat

Heat losses are unavoidable when operating fuel-fired furnaces, kilns, boilers, ovens or dryers. When the energy or heat transfer reaches its practical limit on industrial processes, spent combustion gases are removed from the furnace via a flue or stack to make room for a fresh charge of hotter combustion gases. In most fuel-fired heating systems, this waste heat is the biggest single energy loss in the process, often greater than all other losses combined. By converting this waste heat into a hot water stream through the use of exhaust gas heat exchangers, an ElectraTherm Green machine can convert this heat into usable power or electricity.  Industrial processes that produce waste heat include thermal oxidizers, steam, steam condensate, incinerators and fuel cells.

Biomass / Biogas stations waste heat

ElectraTherm technology captures waste heat from biomass to create electrical power. Typical biomass applications involve the incineration of the biomass material to create the thermal heat for a boiler system. The Green Machine connects to the hot water from the biomass system's boiler to produce fuel-free, emission-free power. Heat sources on a biomass application include bio-based fuels, landfill waste and wood chips boilers. Optimal configurations combine the thermal output value (district heat) with high value on-site electrical production.

Biogas

ElectraTherm technology captures waste heat from biogas-fed electrical generators to create additional electrical power. The Green Machine, connecting to the biogas engine jacket hot water, engine exhaust or a combination of both, captures the waste heat and converts it into electricity. Biogas combined heat and power installations use the remaining heat in the engine jacket water to heat the anaerobic digesters creating the biogas, as well as supplying heat for buildings. Biogas applications are commonly used in areas where agricultural waste from farming and livestock is available, in addition to landfills.

solar thermal ORC


Solar Thermal

ElectraTherm's Green Machine can connect to existing processes of a solar thermal farm to generate additional power. Typical solar farms provide a hot water flow that can be used for combined power and heating loads. The Green Machine converts low temperature liquid heat from the solar thermal application into emission-free power. Depending on the specific solar thermal application, the Green Machine can be implemented in a bottoming cycle, using the direct hot liquid, or steam condensate.

geothermal ORC heat to power


Geothermal / Oil & Gas

Until recently, small-scale, geothermal power generation has been inhibited by the relatively high cost of power plants. Geothermal power plant development has focused on units in the multi-megawatt range, while ignoring smaller heat sources.These smaller heat sources can be a great fit for smaller scale geothermal power generation using ElectraTherm Green Machines. Depending on the heat source available, the Green Machine can be connected directly using the hot liquid, steam condensate, or as a bottoming cycle of another process. The majority of the geothermal resources are enerally lower temperatures (less than 210 °F / 100 °C), and the Green Machine can operate at resource temperatures as low as 170 °F / 77 °C.
