Waste-Heat-to-Power Applications on the Rise | Power Electronics

An important factor in waste-heat-to-power (WHP) generation is the thermodynamic limitations on power generation at different temperatures. The efficiency of power generation depends on the waste-heat source temperature. Generally, power generation from waste heat has been limited to only medium- to high-temperature waste-heat sources.

Biomass for Power and Heat Generation-ZBG Boiler

CHP, also known as co-generation, is the simultaneous production of electricity and heat from a single fuel source, such as biomass/biogas, natural gas, coal, or oil. CHP provides: • Distributed generation of electrical and/or mechanical power. • Waste-heat recovery for heating, cooling, or process applications.
