Coal Mill Control and Optimization Using a Multilayer

May 21 2009 · Abstract Ball mill coal pulverizing system is a multiple-input multiple-output (MIMO) process characterized with strong couplings and nonlinearities. Conventional control methods maybe work well initially but will deviate from optimal work point for a period of time and even cease to be functionally effective.

Modelling and control of pulverizing system considering

Based on the dynamic mathematical model of coal mill pulverized coal moisture was used as a feed-forward signal and a feed-forward compensation controller was designed to optimize the coal mill outlet temperature. Simulation results showed that the dynamic characteristic of the mill can be forecasted effectively with the established model.

Vertical Roller MillsFL

When it comes to grinding raw coal savings in specific energy consumption can be achieved with vertical roller mills. Specific energy consumption depends on the grindability of the raw coal and the coal meal fineness required. A dynamic separator that ensures high separation efficiency also helps to reduce specific energy use.

Reduce risk with coal mill gas analysis FL

Coal dust is a hazard. Spontaneous combustion is a real possibility and once fire breaks out it can be hard to control. Guard against the risk with a coal mill gas analysis system measuring the carbon monoxide levels and giving a warning before they become dangerous.

Modeling and Parameter Identification of Coal Mill

The coal mill used in the coal-fired power plants is modeled in view of the controller design rather than the educational simulator. The coal mass flow and the outlet temperature are modeled by reinvestigating the mass balance and heat balance models physically. The archived data from a plant database are utilized to identify the model parameters.

An area of power plant control that has received much less attention from mod elling and control specialists is the coal mills. This is in spite of the fact that it is now accepted that coal mills and their poor dynamic response are major factors in the slow load take-up rate and they are also a regular cause of plant shut-down (Maffezzoni 1986).
