Nov 17 2012 2Coal pulverizermill system One of the critical power plant components that is relied upon to convert the energy stored in coal into electricity is the coal pulverizer or mill The coal flow is controlled by the feeder allowing coal to flow into the pulverizer mill The pulverized coal and air mixture is then transport to the boiler burner
STARTS consists of a pulverizer and furnace controlling subsystems where drifteddynamicsinfluenced state variables estimated by observers are fed back to manipulations such as the pulverizer inlet coal flow and furthermore the identified parameters dominating the dynamics are reflected on the subsystems In short the strategy of the
A safety control system for a coal pulverizer utilizes signals 2022 representing net oxygen and carbon monoxide measurements of the pulverizer atmosphere A signal 50 representing the rate of carbon monoxide change is derived form the signal 22 by a derivative controller 48 The signals 2050 representing the net oxygen measurement and rate of carbon monoxide change are compared in
The main boiler was built as coalfired which is why pellets were ground in coal pulverizers that were slightly modified for biomass and operated at low temperatures to eliminate the risk of fire Further modernizations and the addition of a fourth mill enabled that in 2014 the boiler was commissioned for 100 wood pellets 76
The fineness of the milling product and the capacity of the pulverizer are strictly connected With increased fineness grows the overall circulation rate of coal in the mill coal retention time and the flow resistance As a result the maximum mill capacity decreases and the rate of change of operational parameters of the furnace system
