Based on the analysis of the failure cause of the rupture occurred in the flange of the medium pressure steam tank, it was indicated in this article that the failure cause of two flanges was the mistake made in designing the discharge pipeline of the safety valve.

It mainly discusses the harmful influence of steam drum pressure to its water level and using T640 intellect circuit regulator to compensite automaticaly to the pressure.

By analyzing the calculation formulas for measuring steam drum water level by different balance container are analyzed,it is stated that the steam drum water level can be measured correctly only by steam drum pressure compensation and cold water compensation.

In order to overcome the nonlinearization, time-variability and pure lag of fuel-drum pressure control loop in the power station, a PID-type fuzzy neural network with a self-regress nerve cell was proposed as the drum pressure controller in the coordinate control system.

Study on energy saving of the steam trap system for the medium-pressure steam system in Baosteel;

Flange leakage of the valve and the suspending hangers of medium-pressure steam piping was observed in one chemical fertilizer plant power branch.
