The Application of Screw Power Generation Technology in the High Pressure Steam Heating System of Thermal Power Plants
Due to the process requirements,there are various throttling and pressure relief devices in the production process of thermal power plants,such as temperature and pressure reducers,pressure relief valves,and regulating valves.Due to the system design and pressure matching reasons,the above-mentioned equipment,while completing their respective functions,have more or less loss of work capacity,which is known as"loss of efficiency".It seems invisible,but it actually consumes avail-able energy.How to convert the invisible loss of throttling and pressure relief into tangible power out-put,while completing basic functions and recycling some of the"loss of efficiency",to achieve energy cascade utilization,is a major issue worthy of exploration in the field of engineering technology.The op-timization design and application demonstration of screw expander power generation technology in the high pressure deaerator inlet system of thermal power plants has promoted a new energy-saving tech-nology and new concept.
