Plate and Shell Heat Exchangers in relation to ORC systems?
Plate and shell heat exchangers are multiplied in Organic Rankine Cycle (ORC) systems. They transfer thermal energy from the heat source to the working media to generate electricity. Plate and shell heat exchangers consist of a series of parallel metal plates and shells through which the heat source and the working fluid flow through the channels between these plates. This construction provides a large heat exchange area, which improves heat transfer efficiency. In addition, plate and shell heat exchangers offer compact construction and low pressure drop, making them ideal for use in ORC systems. According to the requirements of different working conditions and heat sources, the selection of suitable plates and design parameters can meet the realization of efficient heat transfer.
What is an ORC system?
In the industrial field, the general low-temperature waste heat refers to the waste heat gas, condensate, and hot water generated by the industrial production process below 200°C; the heat of gases below 150°C as well as the exhaust gas of boilers and industrial heating furnaces. The main principle of ORC is to transfer low-temperature heat energy to the organic work mass through a heat exchanger, and then through the evaporation, expansion and condensation process, the steam in the work mass is transferred to a turbine to drive a generator to produce electricity.
What are the advantages of ORC low temperature waste heat power generation system?
1. High thermal efficiency: heat transfer oil is the intermediate heat transfer medium, which has the advantages of uniform heat transfer, good thermal conductivity and stability, and basically has no corrosive effect on ordinary carbon steel equipment and pipelines.
2. Wide range of applicable low temperature: In the case of low temperature, ORC is excellent in wet heat recovery, and its efficiency is much higher than the thermal efficiency of Rankine cycle with water as the working medium.
3. Simple structure and small size.
