Reliable coal pulverizer performance is essential for sustained fullload operation of today39s power plants. An effective pulverizer must be capable of handling a wide variety of coals and accommodating load swings in utility boilers as large as 1,300 MW.. BampW39s pulverizers, found at power stations throughout the world.
Holmes Coal Pulverizers are benchtype units that perform well in reducing coal or coke from No. 4 to No. 60 sieve size. Models are available with manual or auger feed. All units are constructed of painted steel and cast iron, and have onepiece balanced rotor with hard coated hammers, driven by 1hp, single phase motor with overload protection.
A pulverized coalfired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.
Noise, Coal Rejects excessive, Capacity Short Repair damaged or worn parts, grinding elements classifier components, etc. Prove by Testing, Best Pulverizer Performance is acceptable Coal Fineness and Coal Distribution. Fineness and Distribution Needs to be Measured to be Managed

Coal pulverizers are the heart of a pulverized coalfueled boiler Often the root causes of nonoptimized combustion lie with the pulverizers.
Design of Pulverizers . Every coal pulverizer is designed with a particular fuel grinding capacity, or throughput, at a certain Hardgrove grindability index HGI, based on moisture content, a defined raw coal size, and desired fineness level. These factors must all be considered and are significant in discussions of pulverizer capacity.
The RETSCH pulverizer range covers applications from the preliminary size reduction of particles of several centimeters to fine grinding down to the nano range. A good pulverizer guarantees reproducible sample preparation, which is the basis for any reliable and accurate laboratory analysis.
