| Abstract: | The drum emergent water discharge is an important safety prevention of steam boiler.The mathematic model of mass balance and energy balance was built when the level of drum water in unsteady state in this paper.The dynamic characteristics of the water lever was analyzed when load changing.The calculation methods of emergent water discharge and withdrawal of the emergent relief pipe were deduced.The control program of the boiler water level was worked out by VB software,and the relative curve of water level and time was debugged. |
