Boiler Drum Level Indication - Spartan Controls

Damage to the steam drum, the boiler, and the turbine can result from inaccurate drum level control. If the drum level falls below set-point, there is a risk of the boiler running dry. If the level is higher than set-point, there is a risk that wet steam could carry over to the turbine, causing damage to the turbine blades.

Practical dynamic matrix control for thermal power

For practical implementation, coordinated control (CC) is an effective application of advanced MIMO control for industrial thermal power plants. Coordinated control between boiler and turbine systems is the uppermost layer of power-plant control. During an emergency, CC can be disconnected anytime without stopping the local SISO loops.

Boiler Chemistry Control and Treatment of Feed Water

Also high concentrations of deposits cause corrosion. So some treatment of feed water is necessary. Details related to boiler water chemistry can be found in Chapter V of Power Plant Instrumentation and Control Handbook: A Guide to Thermal Power Plants (Here only treatment part is discussed, with special reference to Supercritical boilers.)

Operation of Boiler and Conductivity in Drum Water

Water chemistry sensors for both feed water and boiler need monitoring as any impurities in this gets concentrated and gets carried over in the steam. Conductivity controls for water blowdown in the drum type boiler are a method to remove such concentrate. Conductivity is just one of many factors to monitor. Changes in conductivity readings in various area gives a good clue to operators to

For power generation they are used now seldom and are replaced by single drum boilers as the bi drum boilers are non-reheat units. So, due to the high heat rate of the plant a single drum boiler or a once through boiler

Low Drum Level in Boiler Operation - How to Handle

Low drum level operation leads to availability loss of the boiler. Water wall tubes fail due to short term overheating. Never bye-pass the very low drum level trip in boiler is to be adopted. The boiler availability loss due to a low drum level operation can be a major concern in power plants, hence it is always better to take preventives.

Three Element Drum Level Control - Cross Company

2019-10-23 · This arrangement is called "Three Element Drum Level Control" (3E) because the algorithm uses level, BFW flow, and steam flow. "Single Element" (1E) control should be used when either flow is too low or has bad quality . 1E is a simple PID loop with the level as PV, the output going to the valve, and no feed forward.
