What are Coal feeders? Principle, components ...

07-09-2020· Coal Feeder is a device that regulates the amount of coal to be supplied into the Coal Mill. The amount of coal is regulated according to the needs in the boiler combustion chamber (furnace). The number regulation system in the coal feeder can be done in two ways based on the type, namely by weight fraction or coal volume fraction.

Pulverizer - Wikipedia

Types of coal pulverizers. Coal pulverizers may be classified by speed, as follows: Low Speed; Medium Speed; High Speed; Low speed Ball and tube mills. A ball mill is a pulverizer that consists of a horizontal rotating cylinder, up to three diameters in length, containing a charge of tumbling or cascading steel balls, pebbles, or rods.

Dynamic Modeling and Inferential Control of the ...

The control of the pulverizing system is a bottle neck in the control of the power generation process, since the key controlled variables are either unmeasurable or inaccurately measured. To address this problem, this paper studies the control-oriented modeling and the inferential control of the pulverizing system, aiming at improving the control precision.

Steady state inferential modeling of temperature .

25-06-2009· Mill discharge temperature and differential pressure have a strong effect on efficiency and safety of a coal fired power plant. Therefore, it is imperative that they are closely monitored and controlled during mill operation to keep their levels within a predetermined safe and efficient operating range regardless of the rate at which the raw coal is fed to the mill.
