CiteSeerX - Document Details (Isaac Councill Lee Giles Pradeep Teregowda): The paper presents a MISO Wiener-Hammerstein cascade describing the process of a single steam stage The non-linear static part is based on the energy balance of the medias involved in the process The linear part involves the time dependence of the process

Thermal load deviation model for superheater and reheater

· The extreme temperature deviation experienced in the superheater and reheater of a utility boiler can seriously affect its economic and safe operation This temperature deviation is one of the root causes of boiler tube failures (BTF) which causes about 40% of the forced power station outages The steam temperature deviation is mainly due to the thermal load deviation in the lateral
