摘要：

A loop-by-loop approach is used to analyse multivariable water flow and collecting vessel-level control problems during Benson(R) type boiler start-up. It is shown that the circulation loop must be tuned so that its bandwidth is less than the feed water loop bandwidth. (C) 2003 Published by Elsevier Ltd.
