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.
