摘要：[Introduction] With the development of "3060" double carbon target, the usage of the PV and wind power for hydrogen gas production is beco.ing a hot and cutting-edge direction. The co.bustion of natural gas mixed with hydrogen gas in gas turbine of hydrogen gas industry will beco.e the final step to co.vert hydrogen into electric power. The gas turbine unit have pressure regulation station, front module and co.nection pipe. The front module have requirements on the flow rate, pressure, temperature and particle co.tent. And the pressure regulation station will provide the required mixed gas to front module. The co.nection pipe will have a length of 1 000 m which depended on the different arrangement. The character of pressure drop and temperature drop of co.nection pipe will have direct impact on the interface parameter of pressure regulation station. So it is necessary to study the character of pressure drop and temperature drop of co.nection pipe. And it will provide a practicable solution for the future gas turbine fired with natural gas mixed with hydrogen gas. [Method] The fuel demand was given for the H class gas turbine fired with mixture of natural gas and hydrogen gas after the simulation calculation with GT Pro software. The reco.mended material selection and velocity selection were presented based on required temperature and pressure drop by H class gas turbine front module and the physical character of mixed gas. The pipe pressure drop and temperature drop due to pressure drop were also calculated. [Result] The pipe material selection, diameter selection, pipe pressure drop and temperature drop due to pressure drop of pipe are presented. [co.clusion] For present time, the pipe design between natural gas pressure regulation station and gas turbine front module shall evaluate the material, outer diameter, wall thickness, velocity, pipe resistance, etc., each by each under the co.dition with hydrogen gas mixture. Thus the gas turbine can use natural gas at p

[Method] By analyzing the characteristics and current application of offshore wireless co.munication technology and co.sidering the requirements of equipment operation, station warning and personnel activities of offshore co.verter stations, the co.figuration scheme for the wireless co.munication system of offshore co.verter stations was proposed. [Result] Through the NAVTEX system, the requirement to receive weather and safety information is realized. Through the radar optoelectronic system and VHF ship to ship co.munication system, the requirement for vessel caution and expulsion is realized. Through UHF cluster interco. system, WiFi and mobile co.munication system, the daily co.munication requirement of personnel is realized. Through the lifeboat emergency co.munication system, microwave transmission system and satellite co.munication system, the requirement of personnel emergency avoidance is realized. [co.clusion] Therefore, the system can realize the basic co.munication requirements during the daily operation and maintenance of offshore co.verter stations, ensure the safety of equipment and personnel, and provide guidance for the design of wireless co.munication systems for offshore co.verter stations. © 2024 energy china GEDI.
