Coal Pulverizer Pall Corporation

Introduction. Power generation industry studies have shown that coal pulverizers are an area where improved equipment reliability is badly needed. The Electric Research Institute (EPRI) has determined that 1% of plant availability is lost on average due to pulverizerrelated problems.1 EPRI also identified oil contamination and excessive leakage as two areas where pulverizer

Reducing wear particulates in a coal pulverizer gearbox

Typical maintenance costs and intervals for each pulverizer gearbox were as follows: Oil changes 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 timeframe. This particular plant had 13 of these coal pulverizers
