Low-grade waste heat utilization technology
Thread Content
This technology combines the organic Rankine cycle with a screw expander; the entire system consists of an evaporator, an expander, a condenser, and a liquid pump. When recovering low-grade waste heat (waste gas and water vapor at pressures above 0.1 Mpa, as well as hot water or hot fluids at temperatures above 75°C), the recovered heat source heats the working fluid as it passes through the evaporator; this results in high-temperature, high-pressure steam that enters the expansion engine, driving it to perform work and thereby generating electricity. The low-temperature, low-pressure expansion fluid discharged from the expander enters the condenser, where it releases heat to the environment and condenses into a liquid state; this liquid is then pumped into the evaporator to evaporate, thus completing one full cycle. Screw expanders belong to the category of positive-displacement expanders; they have a compact structure, high strength, and are not prone to damage. It has an extremely strong ability to operate under varying conditions, capable of stable operation within a load range of 10% to 120%, making it highly suitable for the recovery and utilization of energy sources with high variability in parameters such as waste heat and residual heat.

We hope that this energy-saving and environmentally friendly technology can help more enterprises. We also welcome partnerships with others in order to promote these initiatives and create mutual benefits. We will treat our partners with sincerity and friendliness; feel free to contact me if appropriate. My phone number is 17017272946, and my QQ account is 2574024302
Is there any relevant material? I’d like to learn about it
Use R124 and the environmentally friendly refrigerant R245fa

Introduction to waste heat and pressure power generation: This method makes use of the waste heat and pressure generated during industrial production processes to generate electricity, thereby achieving the goal of energy conservation and emission reduction. Waste heat sources can be divided into two categories: pressurized steam and low-temperature heat sources.
Screw expanders belong to the category of positive-displacement expanders; they have a compact structure, high strength, and are not prone to damage
Indeed, this is also an advantage that allows it to be used with low-pressure steam and other unstable heat sources
OP, create a QQ group so everyone can communicate and learn together
