Modeling and Control of Coal Mill NTNU

2013-11-20  5. CONTROL OF COAL MILL In general the control systems, of mills have two components: coal air mixture temperature control and the coal feeder control. Control scheme for outlet temperature is essential since improper control may lead to chances of explosion. In the thermal power plant, the outlet temperature

Modeling and outlet temperature control of coal mill

Coal mills are used to grind and dry the raw coal containing moisture and to transport the pulverized coal air mixture to the boiler. Poor dynamic performance of coal mill causes difficulties in

Modelling and control of pulverised fuel coal mills

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).

Coal Mill Modeling for Monitoring and Control

2011-4-30  The application of MPC to coal mills can b e considered in tw o di eren t lev els of complexit y. The rst lev el comprises the con trol tasks related to the op eration of individual coal mills. A typical con trol strategy for a coal mill is based on receiving a coal feeder reference. The con trol loop for the

COAL MILL MODELLING USING EVOLUTIONARY

These preliminary tests were part of a sequence of tests that were undertaken to evaluate the use of feedforward control to maintain the output temperature of the coal-air mixture at a fixed level.

Analysis of coal Mill Dynamic Characteristics Under

1997-8-1  This paper describes the analysis results of the dynamic characteristics of coal grinding mills used in a large coal-fired power generation unit. The aim of the work is to develop a knowledge-based expert power plant operator support/control system (KBOSS) to improve power plant process monitoring and control.

Coal-mill optimisation in coal-fired power stations
