What you don't know about Steam Boiler Drum Level Control

A single element control only uses the drum level signal as the control process variable. After performing a Proportional (P) and Integral (I) computation on the level deviation from setpoint, the output of the controller is then passed to the boiler feed water valve, which then controls the level of feedwater flow into the boiler drum.

A boiler explosion is a catastrophic failure of a boiler.There are two types of boiler explosions. One type is a failure of the pressure parts of the steam and water sides. There can be many different causes, such as failure of the safety valve, corrosion of critical parts of the boiler, or low water level. Corrosion along the edges of lap joints was a common cause of early boiler explosions.

The method of adjusting boiler water level

The water level of the boiler can be accurately judged by regular comparison with the water level gauge. 2. Monitor the main data of steam flow, water supply flow, steam pressure and water pressure at any time, and find out the cause and deal with it promptly when it is found to be abnormal. 3. If the water level exceeds +50mm,Water supply regulating valve should be turned down to reduce water intake.
