Low-Temperature Waste Heat Recovery

High-temperature waste heat is often used in waste heat recovery cycles to produce power. However, micro-turbines, internal combustion engines and fuel cells typically produce low-temperature waste heat that is not used because the temperature of the heat is too low to be useful. Mainstream has developed a commercially beneficial and technically viable Rankine-cycle system to generate power from low-temperature waste heat.

The low-pressure water Rankine-cycle system is the most efficient and commercially viable low-temperature waste heat recovery system. It outperforms all organic Rankine cycle systems and has no environmental issues, such as the global warming potential issues raised by some organic working fluids (HFCs). Mainstream has designed, fabricated and demonstrated a low-pressure water turbine for this waste heat recovery system.
