Design of Hydrogen Production Station for Nanhai No.1 Power Plant
The design of hydrogen production station for Nanhai No.1 Power Plant is presented,and some problems underlining the connection of old and new pipe lines in the process of hydrogen production station reconstruction are discussed. It is proposed to cut off and plug the hydrogen pipe line leading to the main power house after shutdown for hydrogen production station.Remaining hydrogen is purged by nitrogen before on-site welding.Such a design proposal yields sound effect,and some novel and optimized designs such as cooling water system,hydrogen storage system,outsourcing hydrogen system may be referred to by the extension of similar thermal power plant.
Coal mine safety rules show: we must establish and improve dustproof and water supply system in the mine well.Based on the comprehensive study and analysis on the status of water supply system in Tangshan Mining Company Tieyi District and the reconstruction plan of water supply system,this paper used the pipe network hydraulic calculation theory to calculate the existing and new water supply system to build and improve the dustproof and water supply system and ensure safety of mine.
