【Abstract】 The model of heat released from boiler combustion is established by the classical heat signal method.A condensation ratio coefficient is introduced to obtain the steam volume under water level in the drum.A model of drum level dynamics in 300MW natural circulation boilers is presented.Simulation results show that the output fits well with the practical drum level dynamics.更多还原
