Cause Analysis of the Temperature Rise at the Outlet of Process Gas of Hydrogen
Absrtac:As one of the core equipment of hydrogen production equipment,waste heat boilers experience an increase in boiler outlet temperature and a decrease in heat exchange efficiency during operation.Through analysis of factors such as boiler water quality,converter operation,and catalyst performance,it is concluded that the entrainment of catalyst dust into the waste boiler is the main reason for the increase in boiler outlet temperature.Develop an operational plan to address the temperature increase at the outlet of the waste boiler and optimize measures to protect the catalyst during the start-up process.After the maintenance starts,the outlet temperature of the waste boiler is normal,achieving long-term stable operation of the unit.
