摘要

随着国家碳中和和碳峰值战略的实施，航运节能减排技术也受到了公众的关注。由于船舶机舱内有大功率发动机和发电机组，设备运行过程中产生的废气余热温度极高，可高达数千摄氏度。该装置先通过斯特林机将废气余热转化为机械能，再通过外接发电机将其转化为电能。整个工作过程在降低环境温度的同时产生电能，提高了余热的利用效率。根据初步实验，当温度为433℃时，可产生约3.3v电能。该装置结构简单，无复杂的机械结构，安全性高，可靠性强。如果能够在船舶机舱内同时使用多种设备，对实现碳中和和碳峰的目标将有积极的帮助。

Innovation of Thermoelectric Conversion Stirling Device for Recovering Heat from Ship Exhaust Gas

: With the implementation of the national carbon neutralization and carbon peak strategy, the technology of shipping energy conservation and emission reduction has also been concerned by the public. As there are high-power engines and generator sets in the engine room of the ship, the waste heat temperature of waste gas generated during equipment operation is extremely high, which can be as high as thousands of degrees Celsius. The device first converts waste gas waste heat into mechanical energy through Stirling machine, and then converts it into electrical energy through external generator. The whole working process produces electric energy while reducing the ambient temperature, and improves the utilization efficiency of waste heat. According to the preliminary experiment, about 3.3v electric energy can be generated when the temperature is 433 °C . The device has simple structure, no complex mechanical structure, high safety and strong reliability. If multiple equipment can be used in the marine engine room at the same time, it will have a positive help to achieve the goals of carbon neutralization and carbon peak.

期刊介绍： Today, nuclear reactors generate nearly one quarter of the electricity in nations representing two thirds of humanity, and other nuclear applications are integral to many aspects of the world economy. Nuclear fission remains an important option for meeting energy requirements and maintaining a balanced worldwide energy policy; with major countries expanding nuclear energy"s role and new countries poised to introduce it, the key issue is not whether the use of nuclear technology will grow worldwide, even if public opinion concerning safety, the economics of nuclear power, and waste disposal issues adversely affect the general acceptance of nuclear power, but whether it will grow fast enough to make a decisive contribution to the global imperative of sustainable development.
