Billions of dollars lost each year as waste heat from industrial processes can be converted into electricity with Thermoelectric Energy Harvesting Technology. Waste heat recovery and recycling is becoming more popular with the growing renewable energy harvesting technologies. Electric power can be generated from waste heat in two methods, using miniature portable thermal power plant for large amounts of waste heat, and using thermoelectric sensor technology for small amounts of waste heat.

Waste Heat Recovery Units

Waste heat recovery unit (WHRU) is an energy recovery heat exchanger that recovers heat from hot streams with potential high energy content, such as hot flue gases from a diesel generator or steam from cooling towers or even waste water from different cooling processes such as in steel cooling. Waste heat recovery units help to recollect and combine all the waste heat from different sources. Various types of waste heat recovery units are Recuperators, Regenerators, Heat pipe exchanger, Thermal Wheel, Heat Economizer, and Heat pumps.

Portable Thermal Power Plant – Waste Heat Power Generators

Waste Heat Power Generators recover heat from various sources without any specialized electronics or hard-to-maintain components, but using simple waste heat recovery units. By boiling water up to 200°F, the generator can produce from 25kW to 1MW of fuel-free, emission-free electricity.

Thermoelectric Energy Harvester System

Thermal energy harvesting system is an electronic power generation system based on thermoelectric sensor technology. Thermoelectric sensor technology is usually applicable for harvesting smaller amounts waste heat in the order of micro watts to a few watts.
