Pulverised Coal an overview | ScienceDirect Topics. 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 coalfired power generation units of this timeframe.
Power generation industry studies have shown that pulverized coal power plants are an area where improved equipment reliability is essential. The Electric Research Institute (EPRI) has determined that 1% of plant availability is lost on average due to pulverizerrelated problems. EPRI also identified oil contamination and excessive leakage as two areas where pulverizer drive train failures ...

PulverizerAir Air or gas introduced into the pulverizer to convey the pulverized coal from the pulverizer and to dry the coal, if required. Pump Device fortransporting pulverized coal. 2 Seal Air or Gas Air or gas supplied to any
Pulverized coalfired boiler Wikipedia. The raw coal is then fed into the pulverizer along with air heated to about 650°F / 340°C from the boiler. As the coal gets crushed by the rolling action, the hot air dries it and blows the usable fine coal powder out to be used as fuel. The powdered coal from the pulverizer is directly blown to a ...
