Comparative Analysis of Valve Schemes for Gas Boiler Fuel System
[Purposes]To fully utilize the surplus gas in the steel plant and improve the self generation rate,the gas boiler generator is an important facility for the utilization of surplus energy.However,gas valves are an important component of the fuel system of gas boilers,playing a crucial role in the safety and economy of power generation units.Therefore,it is necessary to compare and analyze the gas valve schemes to find a safe,economical,and reasonable configuration scheme.[Methods]Through the study of relevant regulations at home and abroad,combined with engineering practice experience,this paper fo-cuses on analyzing the common types and configuration schemes of partition devices,quick shut-off valves,and regulating valves in fuel systems.[Findings]Through analysis and comparison,it was found that each specification only has principle requirements for the setting of quick shut-off valves and regu-lating valves,and there are no specific requirements for the quantity and installation position.The con-figuration of valves needs to be combined with the actual engineering situation.[Conclusions]To bal-ance safety and economy,three recommended gas valve configuration schemes have been proposed,which can be selected according to different unit capacities in engineering practice.
