Influence of steam supply parameters variation on performances of steam accumulator system
Analysis of off-design performance on the steam accumulator charge system is a key link in the investigation into the system control strategy.A mathematic model for each system component was established based on variable-mass system thermodynamics and viscous fluid mechanics theories.Then,a solution was proposed to calculate the system model.The adjustment of the joint operating parameter(the charging steam flow) resulted in obtaining the system performance parameters which met the requirement of steam supply.On this basis,the influence of steam supply parameters variation on the system performances was simulated and calculated.The result shows that the temperature of steam supply has less influence on the system performance,while a decrease in the steam pressure will lead to failing to meet the requirement of steam supply under the original control strategy.
