Approach to dynamic variation of inner wall's temperature for boiler's drum with load change

摘要

Inaccordance with the structural and thermal characteristics of HG 410/t/h super high pressure boiler, ta lumped parameter model for the drum was presnted by using the method of dynamic analysis, The model was base don some reaosnable simplified supposition for dynamic process in drum, and the dynamci variations were calculated for the temperature of drum's inner wall, druing the load chang. (step, square wave, saw tooth wave disturbance).
