Coal Pulverizer Gearbox Filtration Upgrade. A coal-fired power plant typically has several coal mills feeding fluidized coal dust to fire each turbine. The gearboxes these coal mills utilize can have high levels of particulate contamination as fine coal dust passes by shaft seals into the high viscosity gear …
A coal-fired power plant operating in the western U.S. was experiencing short gearbox life in its coal pulverizing operation. The AGMA 6EP (ISO 320) gear oil recommended by the OEM failed to provide adequate lubrication and protection based on oil analysis results and gearbox …
Babcock & Wilcox (B&W) is now applying its vast experience and knowledge of roll wheel and ball-and-race pulverizers to provide quality replacement parts, services and inventory management programs to Combustion Engineering (CE)-type mills / pulverizers. Since 1867, B&W has set the standard for proven high availability, reliability and low maintenance on its boilers, pulverizers and other ...
In this device coal is crushed by a pulverizer to 200 mesh and transmitted to the storage tank through cyclone pneumatically. The storage tank is equipped with bag filters to remove excess air. The feeding is done by worm gear having finger system, so that there is no sticking in the coal powder.
In fact, typical maintenance costs and intervals for each pulverizer gearbox were as follows: • Oil changes were required every 12 months at a cost of $5,000 in material and labor and $20,000 to $50,000 in lost electrical production, typical of most coal-fired power generation units of this time frame. • After 10 years of operation, the ...
