online coal fineness measurement system

EUcoalsizer Online measurement of coal flow and particle

2012-3-22  The coal particle size spectrum has a strong impact on the combustion process. It influences ignition delay, combustion efficiency and LoI (loss on ignition), the emission levels as well as slagging and fouling. Despite the significance of this property, there has not yet been a robust and easy to handle system for the online measurement of coal fineness inside the pipe. EUcoalsizer solves this problem. The system measures the particle size distribution and the coal and air flow inside a measurement

CPRI Online Coal Flow Balancing and Fineness

2020-3-19  ABSTRACT: The paper describes the beneficial application of online coal flow measurement and control and online coal fineness measurement for optimization of the combustion process inside coal-fired boilers. The system automatically balances the coal flow from pipe to pipe and monitors continuously the flow behavior. In combination with the online measurement of particle fineness the combustion efficiency, unburnt carbon and fouling are continuously optimized. The coal flow measuring system

2020-3-19  The system measures particles in the range from 20 µm up to 4 mm and velocities up to 160 ft/s. By traversing the lance through the pipe, spatially resolved measurements along the cross section of the coal pipe are collected and analysed online. This permits direct correlations and feedback control between the mill settings (hopper load, mill speed and classifier setting) and the boiler behaviour

Pulverizer Fineness

Importance of Fineness. Higher fineness levels always promote more even distribution of fuel between a pulverizer’s separate burner lines. Better distribution promotes better combustion, inherently lower NOx emissions and lower flyash L.O.I. or carbon content. The graph below illustrates actual test data on a pulverizer with varied fineness.
