A mechanism model of coal pulverizing system is developed to calculate the coal powder flow rate entering the combustion chamber with the data of a 300MW coal-fired power plant. This model is going to be used to improve the identification accuracy of the calorific value, which usually takes the coal flow rate entering the coal feeder as the input.

The paper presents a mathematical model and its Matlab/Simulink realization for ball mill coal-pulverizing system (BMCPS). Based on the analysis of mass and energy balance, the physical models for all control-related sub-processes of BMCPS are developed respectively. Then the integrated dynamic mathematic model is constructed with Matlab/Simulink.

Pulverizer 12 is known as a horizontal type high speed coal mill and is closely based on a duplex model ATRITA Pulverizer sold commercially by Babcock Power Inc. However, this should not be interpreted as limiting the present invention in any way, as these types of pulverizers incorporate the same basic elements of importance that render it

Feb 20, 2011 The model contains the pulverizer-coal combination optimization and optimum output of each pulverizer, which are solved by exhaustive algorithm and non-dominated sorting genetic algorithm II(NSGA-II) respectively. It has now been successfully applied in the Dynamic Coal Blending Optimization System of Guangdong Red Bay Power Plant.

Pulverizer housing or burner lines are glowing red. Mill fires require immediate attention to prevent damage to the pulverizer and more damaging mill “puffs”. Explosions in a pulverized coal system are normally called “puffs.”. A mill puff is an explosion in the mill system caused by an explosive combination of coal, air and temperature.

As we have mentioned before, our goal for optimum combustion is to attain a minimum of 75% passing 200 Mesh with 0.5% remaining on the 50 Mesh at pulverizer full load. Higher fineness at full load can cause extremely high fineness at lower coal flows. In some instances in which pulverizer fineness has been achieved, higher fineness levels

Pulverized Coal Explosions in the U.S. Utility Industry

Ignition events remaining within the coal pipe created only weak pressure rise, while ignition events within a simulated pulverizer volume created explosions exceeding 70 bar gage (1015 psig). These experiments showed that explosion characteristics depend on dust concentration, ratio of pulverizer volume to coal pipe area, as well as coal type.
