·Babcock Power Inc company has been developing improved coal pulverizer technology during the past several years to meet these challenging demands All three 3 types of coal pulverizer systems supplied by RPI originally designed for low medium and high speed pulverization have undergone design upgrades and machines
·Coal pulverizers play a critical role in the functioning and performance of a PC fired boiler The main functions of a pulverizer are crushing drying and separating the fine coal particles
·Coal parameters affecting pulverizer output While selecting a pulverizer the coal characteristics play an important role The Hardgrove index total moisture input coal size output fineness and mill wear have direct impact on the mill output The Hardgrove index of coal tells us about the ease with which it can be pulverized
·And for a simplified industrial pulverizer Vuthaluru et al have conducted numerical simulation to compare the motion of air and 100 μm and 500 μm coal particles He found that trajectories of 100 μm coal particles qualitatively well overlapped on air path lines while significant deviation existed between velocity vectors of 500 μm coal
·• Size of pulverizer coal particles leaving the pulverizer Fineness • System resistance of each individual fuel conduit • Total airflow through the pulverizer which is controlled on a ratio of weight of air to fuel • Velocity of air/coal mixture passing through each burner line • Maintenance of critical components such as the
Grinding of coal petcoke clay limestone quicklime gypsum and many other materials The MPS vertical roller mill built to last reliable and energy efficient is the optimum solution when it comes to performing several process steps in one unit Advantages of the MPS vertical mill Low capital expenditure
Coal is crushed to desired fineness between spheres or cylindrical rollers After that air from the boiler is heated to around 330°C 650°F The raw coal is then fed into the pulverizer where it is ground into fine coal particles What are the Advantages of Pulverized Coal Pulverized coal produces a larger amount of heat than traditional coal
